The introduction of a new collagen substitute, which will potentially reduce the invasiveness of techniques by avoiding the need for a second surgical site (ie, the donor site), needs to be evaluated in relation to the surgical procedure that could benefit the most by utilizing such a matrix. This study compared the clinical outcomes following treatment of RT1 multiple adjacent gingival recessions (MAGRs) using the modified coronally advanced tunnel (MCAT) technique or the multiple coronally advanced flap (MCAF) in conjunction with a new volume-stable xenogeneic collagen matrix (VXCM). Secondarily, the study evaluated whether patients report a preference between the two surgical techniques in terms of discomfort. A total of 20 patients requiring treatment of MAGRs were randomly assigned to one of the two treatment groups: MCAF+VCMX (Group A) or MCAT+VCMX (Group B). The following measurements were recorded at baseline (before surgery) and at 6 and 12 months: gingival recession depth (REC), probing pocket depth (PD), keratinized tissue width (KTW), and gingival thickness (GT). Postoperative pain and discomfort were recorded using a visual analog scale (VAS) at 1 week. The primary outcome variable was mean root coverage (mRC), and secondary outcomes were complete root coverage (CRC), changes in KTW and GT, patient discomfort and satisfaction, and duration of surgery. Healing was uneventful in both groups. At 12 months, both treatments resulted in statistically significant improvements in REC and GT compared to baseline (P < .05). The mRC was 79.95% ± 29.92% in the MCAF group and 64.74% ± 40.5% in the MCAT group (P = .124). CRC was seen in 65.6% of MCAF-treated sites and 52% of MCAT-treated sites (P = .181). Similar clinical results should be expected when MAGRs are treated with MCAF or MCAT, with the adjunct of VCMX. [ABSTRACT FROM AUTHOR]

Following implant placement, a soft tissue barrier will form at the healing abutment connection called peri-implant mucosa. The dimension of this anatomical structure seems to play a key role in maintaining long-term peri-implant and marginal bone level stability. In its early stages, soft tissue healing is a process involving many cellular and molecular events. Enamel matrix derivative (EMD) may improve and accelerate soft tissue wound healing and inflammatory resolution. In the present split-mouth randomized clinical trial, EMD was used to influence the early phase of soft tissue healing around dental implants placed with a single-stage approach into a completely healed ridge. A total of 60 implants were placed in 30 patients (2 implants per patient, one in the test group and one in the control group). In the test sites, EMD was administered around the healing abutment before soft tissues were sutured. Soft tissue healing index (HI) and secondary endpoints (clinical, radiographic, and patientreported outcomes) were measured. Better outcomes were recorded in patients receiving EMD for all parameters. The present results support the use of EMD to improve and accelerate soft tissue wound healing around implants.

Objectives: This study examined the impact of injectable plateletrich fibrin (iPRF) and concentrated growth factor on postoperative pain, edema, trismus, and quality of life in impacted mandibular third molar surgery. The primary aim of this study was to minimize common sequelae following third molar surgery by using iPRF and concentrated growth factor. The secondary objective was to compare the postoperative effects of these products. Method and materials: This study represents a single-center, randomized prospective clinical trial conducted at the Ordu University Faculty of Dentistry. It involved patients who underwent third molar surgery for various reasons between July and October 2022. The predictor variables were the use of concentrated growth factor and i-PRF. They were categorized as concentrated growth factor, i-PRF, and control groups. The outcome variables include pain levels and analgesic consumption measured on a visual analog scale, distances between predetermined anatomical points, maximum mouth opening capacity, and data from the postoperative symptom severity (PoSSe) scale. Some statistical tests were performed with a 95% confidence interval, which was considered significant. Results: Total analgesic use was notably lower in the concentrated growth factor group (P = .044). Concentrated growth factor and iPRF outperformed the control group in all edema measurements by postoperative day 7 (tragus–pogonion, lateral canthus–angulus, tragus–commissura; P < .05). Concentrated growth factor significantly reduced trismus on days 2 and 7. Quality of life was notably higher in the concentrated growth factor group than in the control group (P = .026), although iPRF group differences were not significant. Conclusion: The results indicate that concentrated growth factor has a limited impact on postoperative pain, but significantly reduces edema, trismus, and enhances quality of life. The iPRF group experienced positive effects on pain, edema, and trismus, although the statistically significant differences observed with concentrated growth factor highlight its potential for use instead of iPRF after third molar surgery. An increased sample size is essential for more comprehensive results [ABSTRACT FROM AUTHOR]

INTRODUCTION: Across specialties, surgeons over-prescribe opioids to patients after surgery. We aimed to develop and implement an evidence-based calculator to inform post-discharge opioid prescription size for gynecologic oncology patients after laparotomy. METHODS: In 2021, open surgical gynecologic oncology patients were called 2-4 weeks after surgery to ask about their home opioid use. This data was used to develop a calculator for post-discharge opioid prescription size using two factors: 1) age of the patient, 2) oral morphine equivalents (OME) used by patients the day before hospital discharge. The calculator was implemented on the inpatient service from 8/21/22 and patients were contacted 2-4 weeks after surgery to again assess their opioid use at home. RESULTS: Data from 95 surveys were used to develop the opioid prescription size calculator and are compared to 95 post-intervention surveys. There was no difference pre- to post-intervention in demographic data, surgical procedure, or immediate postoperative recovery. The median opioid prescription size decreased from 150 to 37.5 OME (p

Objective: Mucogingival surgery involving tissue grafts is commonly employed for cosmetic procedures like root coverage, and is increasingly applied in implant therapy to modulate peri-implant soft tissues and enhance implant survival. These procedures involve harvesting autologous connective or epithelial connective tissue, often from the palate or tuber maxillae. However, this can cause patient morbidity due to postoperative pain. Substitute materials, including animal-derived and xenografts, have been developed but lack qualities of autologous grafts. Method and materials: To address postoperative discomfort, a novel technique, named "palatal shield," using composite resin stabilized on adjacent teeth's palatal surface is proposed as an aid to donor site healing after mucogingival procedures. Two cases are reported where this technique was successfully applied. The first case involves a 53-year-old woman undergoing free gingival graft surgery for peri-implant treatment. The second case features a 58-year-old man receiving subepithelial connective tissue graft surgery for root sensitivity. Results: Ten days post surgery, both patients reported excellent postoperative comfort. The technique's effectiveness is highlighted in these cases, demonstrating its applicability in various surgical cases involving free gingival graft or connective tissue graft harvesting. Conclusion: The proposed "palatal shield" technique offers several advantages, including enhanced patient comfort, ease of application, and cost-effectiveness, making it a promising addition to mucogingival surgical procedures.

Purpose: To assess the pain, swelling, infection, and alteration in sensation following the flapless placement of zygomatic implants guided by dynamic navigation. Materials and Methods: A randomized controlled trial was conducted on 20 patients. In group 1, the placement of the zygomatic implants was carried out without reflecting a mucoperiosteal flap (flapless). In group 2, a mucoperiosteal flap was raised (flapped). Two zygomatic implants were placed in each patient (one on each side) under local anesthesia, guided by dynamic navigation. Postoperative evaluations included pain (using the visual analogue scale [VAS]), swelling (using standard measurements), maxillary sinus infection, and alteration of sensation (using mechanical stimuli, thermal threshold detection, and a two-point discrimination test). The assessments were carried out at 2 days, 1 week, and then 1, 2, and 3 months postoperatively. Results: In group 1, all implants except for one were successfully osseointegrated. Immediate postoperative pain and swelling were both significantly greater in group 2 (P < .01). No alteration in sensation was detected in any case in the two groups. There were a total of three cases of chronic sinusitis: one in group 1 and two in group 2. Conclusions: The flapless placement of zygomatic implants guided by dynamic navigation and under local anesthesia improves postoperative recovery. [ABSTRACT FROM AUTHOR]

BackgroundThere is still a controversy about the superiority of liposomal bupivacaine (LB) over traditional local anesthetics in postoperative analgesia after thoracic surgery. This study aims to determine the effect of LB versus bupivacaine hydrochloride (HCl) for preoperative ultrasound-guided erector spinae plane block (ESPB) on postoperative acute and chronic pain in patients undergoing video-assisted thoracoscopic lung surgery.MethodsThis multicenter, randomized, double-blind, controlled trial will include 272 adult patients scheduled for elective video-assisted thoracoscopic lung surgery. Patients will be randomly assigned, 1:1 and stratified by site, to the liposomal bupivacaine (LB) group or the bupivacaine (BUPI) HCl group. All patients will receive ultrasound-guided ESPB with either LB or bupivacaine HCl before surgery and patient-controlled intravenous analgesia (PCIA) as rescue analgesia after surgery. The numeric rating scale (NRS) score will be assessed after surgery. The primary outcome is the area under the curve of pain scores at rest for 0-72 h postoperatively. The secondary outcomes include the total amount of opioid rescue analgesics through 0-72 h postoperatively, time to the first press on the PCIA device as rescue analgesia, the area under the curve of pain scores on activity for 0-72 h postoperatively, NRS scores at rest and on activity at different time points during the 0-72 h postoperative period, Quality of Recovery 15 scores at 72 h after surgery, and NRS scores on activity on postsurgical day 14 and postsurgical 3 months. Adverse events after the surgery are followed up to the postsurgical day 7, including postoperative nausea and vomiting, fever, constipation, dizziness, headache, insomnia, itching, prolonged chest tube leakage, new-onset atrial fibrillation, severe ventricular arrhythmia, deep venous thrombosis, pulmonary embolism, pulmonary atelectasis, cardiac arrest, ileus, urinary retention, chylothorax, pneumothorax, and organ failure. Analyzes will be performed first according to the intention to treat principle and second with the per-protocol analysis.DiscussionWe hypothesize that LB for preoperative ultrasound-guided ESPB would be more effective than bupivacaine HCl in reducing postoperative pain in video-assisted thoracoscopic lung surgery. Our results will contribute to the optimization of postoperative analgesia regimens for patients undergoing video-assisted thoracoscopic lung surgery.Clinical trial registration:http://www.chictr.org.cn, identifier ChiCTR2300074852.

Objective: To assess the effect of intraoperative cryoanalgesia on subjective pain scores of patients after tonsillectomy. Methods: A systematic review of PubMED, Web of Science, EMBASE was performed using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) standards. For the first time, we included and quantitative synthesized English-language randomized controlled trials (RCT) evaluating patients of all age groups with benign pathology who underwent tonsillectomy with intraoperative cryoanalgesia versus without. Results: A total of 835 publications were identified, and 7 articles with 463 participants met our criteria were selected for meta-analysis. The standard mean difference for overall subjective pain score, subjective pain scores at postoperation Day1 (POD1), POD7 were −1.44 with 95% confidence interval (CI) [−2.17, −0.72], P =.0001; −1.20 with 95% CI [−1.89, −0.50], P =.0007; −0.90 with 95% CI [−1.46, −0.35], P =.001 respectively, both in favor of cryoanalgesia. Nevertheless, subgroup analysis by surgical technique showed no robust effect between hot technique and "relative" hot technique on overall pain: (−1.72, 95% CI [−2.71, −0.73]) vs. (−1.06, 95% CI [−2.20, 0.07]), p=.39; on POD1: (−1.56, 95% CI [−2.78, −0.33]) vs. (−0.97, 95% CI [−1.83, −0.11]), p=.39; and on POD7 (−1.11, 95% CI [−1.81, −0.40]) vs. (−0.89, 95% CI [−2.02, 0.25]), p=.13. The standard mean difference for postoperative secondary bleeding rate was 1.29 with 95% CI 0.37,4.52], p =.06, no difference in 2 groups. Conclusion: Limited evidence suggests that intraoperative cryoanalgesia during tonsillectomy leads to lower subjective pain score on overall, POD1 and POD7 without differences on post-operation bleeding rate.

Background: Peripheral nerve blocks effectively alleviate postoperative pain. Animal studies and human research suggest that opioid tolerance may reduce the effectiveness of local analgesics. The reduced effectiveness has been observed in opioid‐tolerant humans and animals undergoing spinal and infiltration anaesthesia with both lidocaine and bupivacaine. However, the impact on peripheral nerve blocks in humans has not been evaluated. This study aims to assess the onset time and duration of a radial nerve block in opioid‐tolerant individuals compared to opioid‐naive individuals. We hypothesise that peripheral nerve blocks may be less effective in producing sensory and motor blockades in opioid‐tolerant individuals compared to their opioid‐naive counterparts. Methods: Twenty opioid‐tolerant individuals will be matched by sex and age with opioid‐naïve counterparts. Participants will receive an ultrasound‐guided radial nerve block. The primary outcome is the difference in the duration of sensory nerve blockade between the two groups. The secondary outcomes include the onset time of sensory blockade, onset time of motor blockade, and difference in duration of motor nerve blockade. Conclusion: This study will compare the effectiveness of a peripheral nerve block between opioid‐tolerant and opioid‐naïve individuals. Any found differences could support a specific postoperative protocol for opioid‐tolerant individuals regarding the use of peripheral nerve blocks. [ABSTRACT FROM AUTHOR]

Background: Treatment with opioids is a mainstay in perioperative pain management. While the leading treatment paradigm has been procedure‐specific pain management, efforts regarding personalized pain treatment are increasing. The OPI•AID project aims to develop personalized algorithms for perioperative pain management, taking demographic, surgical, and anaesthesiologic factors into account. We will undertake five parallel reviews to illuminate current evidence on different aspects of individual responses to perioperative opioid treatment. Methods: Inclusion of adult populations in English‐written studies. Review‐specific searches are developed for the following databases: CENTRAL, MEDLINE, Embase, clinicaltrials.gov, and clinicaltrial.eu. Two authors will independently screen citations, extract data, and assess the risks of bias in each review (QUIPS, PROBAST and RoB2, as relevant). Conclusion: These reviews will evaluate various aspects of perioperative opioid treatment, including individualized treatment strategies, selection of specific opioids, and individual patient responses. These will guide future development of a personalized perioperative opioid treatment algorithm (OPI•AID) that will be validated and tested clinically against standard of care. [ABSTRACT FROM AUTHOR]

Background: Over the past 25 years, global opioid consumption has increased. Denmark ranks fifth in opioid use globally, exceeding other Scandinavian countries. Postsurgical pain is a common reason for opioid prescriptions, but opioid use patterns after patient discharge from the hospital are unclear. This study examines trends in opioid prescription among Danish surgical patients over a year. Methods: This register‐based cohort study will use data from Danish governmental databases related to patients undergoing the 10 most frequent surgical procedures in 2018, excluding cancer‐related and minor procedures. The primary outcome will be the dispensed postoperative opioid prescriptions at retail pharmacies over four quarters. Secondary analyses will include associations with sex, age, education attainment, and oral morphine equivalent quotient. Surgical treatments and diagnoses will be identified using NOMESCO procedure codes and ICD‐10 codes. Opioids will be identified by ATC codes N02A and R05DA04. Subjects will be classified as preoperative opioid consumers or non‐opioid consumers based on opioid prescriptions redeemed in the 6 months before surgery. Discussion: The study will use extensive national register‐based data, ensuring consistent data collection and enhancing the generalizability of the findings to similar healthcare systems. The study may identify high‐risk populations for long‐term opioids and provide information to support opioid prescribing guidelines and public health policies. [ABSTRACT FROM AUTHOR]

Background: Despite advancements in surgical and anesthesia techniques, acute and persistent postoperative pain are still a common challenge. Postoperative pain has direct effects on individual patient care and outcome, as well as putting strain on limited health care resources. Several prediction methods for postoperative pain have been described. One such method is the assessment of pain during peripheral venous cannulation (VCP). It is not known if different approaches to anesthesia and analgesia, depending on the evaluation of risk for postoperative pain, can improve outcome. The aim of this study is to evaluate if individualized anesthesia and analgesia can affect postoperative pain and recovery after surgery, in patients stratified by VCP. Methods: Adult patients scheduled for laparoscopic surgery undergo pain‐sensitivity stratification using VCP on the day of surgery. Patients scoring VCP ≥2.0 on the visual analogue scale (pain‐sensitive) are randomized to multimodal anaesthesia and analgesia with opioids or standard of care. Patients scoring VCP ≤1.9 (pain‐tolerant) are randomized to opioid‐free anaesthesia or standard of care. The primary outcome is acute postoperative pain measured with numeric rating scale in the postoperative care unit. Secondary outcomes include analysis of pain after 24 h, persistent postoperative pain and quality of recovery. Discussion: Individualized perioperative pain management has the potential to improve patient care. This study will examine the impact of different anesthesia and analgesia regimes, in patients with differing pain sensitivity, on postoperative pain. Trial Registration: Prospectively posted at ClinicalTrials.gov, identifier NCT04751812. [ABSTRACT FROM AUTHOR]

Objective Our objective was to compare patient perceived control and experience with outpatient versus inpatient cervical ripening. Study Design This is a retrospective mixed-methods analysis of a quality improvement initiative focused on the impact to patients of incorporating outpatient cervical ripening into routine practice. Postpartum inpatients who had elected for outpatient cervical ripening (outpatients) and those who met criteria for outpatient cervical ripening but opted for an inpatient setting (inpatients) were invited to participate in the study. Patients completed the Perceived Control in Childbirth Scale, and scores were compared between outpatient and inpatient groups using Mann–Whitney U test. In addition, semistructured questions elicited feedback prior to hospital discharge, and these qualitative data were analyzed using iterative thematic analysis. Results The study population consisted of 36 outpatients and 38 inpatients. The median score on the Perceived Control in Childbirth Scale was 69 for outpatients and 67 for inpatients (p -value = 0.49), out of a maximum score of 72 (representing the highest level of perceived control). Both groups reported similarly high levels of perceived control, regardless of cervical ripening setting. In the qualitative analysis, pain was the most common theme in both groups. Inpatients reported more distress despite access to stronger pain medications. Outpatients utilized a variety of distraction techniques and expressed gratitude for their setting more than inpatients. Conclusion Outpatient cervical ripening can be a patient-centered solution to obstetric throughput challenges arising from increased numbers of inductions. Those who underwent outpatient cervical ripening had similar perceived control to those who underwent inpatient cervical ripening, suggesting that individual patient preferences are most important in determining the optimal setting for care. The patients' reported experiences identified focus areas for process improvement efforts and future research, including improving patient education regarding expectations and innovating new pain management strategies for cervical ripening. Key Points Patient experiences must inform patient-centered care. Perceived control with cervical ripening was high. Pain with cervical ripening was the most cited theme. [ABSTRACT FROM AUTHOR]

To compare the perioperative analgesic effect of lateral versus latero-ventral quadratus lumborum block (QLB) in dogs undergoing laparoscopic ovariectomy. Randomized, blinded clinical study. A total of 15 client-owned female dogs undergoing laparoscopic ovariectomy. Animals were randomly assigned to receive a bilateral QLB, performed with 0.3 mL kg–1 ropivacaine 0.5%, either with lateral (group L QLB , n = 7) or latero-ventral approach (group LV QLB , n = 7). Dogs were premedicated intramuscularly with methadone 0.2 mg kg–1 and dexmedetomidine 3 μg kg–1. General anaesthesia was induced intravenously (IV) with propofol and maintained with isoflurane. Cardiovascular and respiratory variables were continuously monitored and recorded every 5 minutes during surgery. Fentanyl 3 μg kg–1 was administered IV if there was a 20% increase in heart rate and/or mean arterial pressure from previous values recorded 5 minutes before. Meloxicam 0.2 mg kg–1 was administered IV to all dogs during recovery. The short-form of the Glasgow Composite Pain Scale was used hourly for 8 hours post-QLB. Methadone 0.2 mg kg–1 was administered IV when pain score was ≥ 6/24. A chi-square test compared the number of dogs requiring intraoperative rescue fentanyl. A Friedman test with a Dunn's post hoc was used to evaluate the trend in postoperative pain scores within each group, and a Mann–Whitney U test compared scores between the groups at each time point; p < 0.05. Significantly fewer dogs required intraoperative rescue fentanyl in group L QLB than in group LV QLB. No dog required postoperative rescue methadone, and there were no significant differences in pain scores. Bilateral QLB performed with lateral approach reduced the number of dogs requiring intraoperative rescue analgesia in comparison with the latero-ventral approach. No differences were detected postoperatively, possibly owing to the confounding effects of methadone, dexmedetomidine and meloxicam. [ABSTRACT FROM AUTHOR]

Phase 1: to determine the feasibility of desensitizing ventral branches of spinal nerves within the rectus sheath using an ultrasound-guided rectus sheath block (USRSB). Phase 2: to determine the effect of preoperative USRSB on intraoperative responses to surgical stimulation and postoperative pain. Cadaveric study and prospective, randomized, blinded, parallel-arm clinical trial. A group of five cat cadavers and 37 shelter-owned cats undergoing ovariohysterectomy. Phase 1: anatomical dissection was performed on one uninjected cadaver. Abdominal walls were dissected in four cadavers (eight hemiabdomens) following bilateral USRSB using 1:1 new methylene blue and 0.5% bupivacaine (0.8 mL kg–1 total). Phase 2: preoperative bilateral USRSB was performed with 0.8 mL kg–1 of 0.25% bupivacaine (RSB) or equivalent volume of 0.9% saline (CONTROL). Intraoperative systolic arterial blood pressure (SAP), heart rate (HR), respiratory rate (f R) and vaporizer setting (vap%) were recorded before skin incision, during celiotomy and abdominal wall closure. In recovery, cats were administered robenacoxib (2 mg kg–1; CONTROL) or 0.9% saline (0.1 mL kg–1; RSB) subcutaneously. Postoperative pain was evaluated for 6 hours using the Glasgow Composite Measure Pain Scale. Phase 1: spinal nerves T9–L3 were identified within the rectus sheath, and stained in 0%, 40%, 63%, 75%, 100%, 88%, 50% and 13% of hemiabdomens, respectively. Phase 2: 37 cats were included (RSB, n = 17; CONTROL, n = 20). Intraoperatively, SAP, HR and f R were not significantly different between groups. Vap% was significantly lower in RSB during celiotomy (p = 0.036) and closure (p = 0.044). Postoperatively, RSB cats were 5.3 times (95% CI 1.8–8.3) more likely to require rescue analgesia than CONTROL cats. During surgery, USRSB with bupivacaine offered minor benefits and provided markedly less postoperative analgesia than robenacoxib, indicating that relying on USRSB provides insufficient postoperative analgesia for ovariohysterectomy in cats.

Objective: The impact of a transversus abdominis plane (TAP) block in patients undergoing cesarean section requires further evaluation. The aim of this study was to compare postoperative pain scores and opioid use in cesarean surgery patients undergoing either a TAP block and scheduled multimodal pain management (SMPM) or SMPM alone. Methods: In this retrospective, dual cohort study, cesarean surgery patients underwent neuraxial anesthesia and a TAP block (SMPM/TAP) or SMPM; the TAP block incorporated ropivacaine (20–30 mL) administered bilaterally. The group analyses involved a comparison of postoperative pain scores using the visual analog scale and opioid consumption at 24 and 24–48 h. Results: There were 94 (52.8%) patients in the SMPM/TAP group and 84 (47.2%) subjects in the SMPM alone group. At 24 h postoperatively, the SMPM/TAP group exhibited significantly lower pain scores (4.07 vs 4.54) than the SMPM group (P < 0.001) and reduced opioid consumption (2.29 vs 3.28 mg; P < 0.001). However, at 24–48 h, the SMPM group demonstrated lower pain scores (5.46 vs 5.98) compared to the SMPM/TAP group (P < 0.001) and reduced opioid consumption (8.75 vs 10.21 mg; P < 0.001); overall opioid consumption was higher (12.50 vs 12.02 mg) in the SMPM/TAP group (P < 0.001). Conclusion: The TAP block improved cesarean surgery patients' pain scores and reduced opioid consumption at 24 h postoperatively but the effect of the TAP block was ephemeral as the SMPM/TAP group exhibited inferior pain scores and greater opioid consumption compared to the SMPM group at 24–48 h postoperatively. Synopsis: A TAP block is potentially an effective adjunct to neuraxial anesthesia in endeavoring to reduce postoperative pain and opioid consumption for patients undergoing cesarean section.

Introduction: Traction on the per-urethral catheter is commonly employed after monopolar transurethral resection of the prostate (mTURP) to reduce bleeding. However, its efficacy and impact on postoperative pain remain uncertain. Further, there is limited evidence to suggest any benefit regarding post-operative blood loss. Materials and methods: In a randomized controlled trial, 62 patients undergoing mTURP were assigned to either a traction (n = 30) or non-traction (n = 32) group. Blood loss, postoperative pain, and analgesic requirements were assessed between January 2022 and April 2023. {(IHEC-PGR/2021/DM/M.Ch/Jan/02), CTRI Registration: CTRI/2022/01/039199.} Results: No significant differences were observed between the traction and non-traction groups regarding postoperative blood loss (p -value- 0.632), fall in hemoglobin (p -value- 0.719) and hematocrit (p -value- 0.937) levels, and length of postoperative hospital stay (p -value- 0.797). However, the traction group reported significantly higher postoperative pain scores (p -value < 0.001) and increased analgesic requirements (p -value < 0.001). Conclusion: The study suggests that 12-hours catheter traction after mTURP does not reduce blood loss and is associated with increased postoperative pain. [ABSTRACT FROM AUTHOR]

Introduction: Minimally invasive surgery is considered the gold standard for the treatment of gynecological diseases. Our study aims to assess the effectiveness of the new concept of ultra-low-impact laparoscopy as a combination of low-impact laparoscopy, consisting in the use of miniaturized instruments through 3–5mm ports and low-pressure pneumoperitoneum, with regional anesthesia to evaluate the perioperative outcomes. Methods: A cross-sectional study was performed from May 2023 to December 2023, to enroll 26 women affected by benign gynecological disease and threated by mini-invasive surgical approach. The surgical procedures were performed following the low-impact laparoscopy protocol and the regional anesthesia protocol. The postoperative pain, nausea, and vomiting and the antiemetic/analgesic intake were evaluated. Postoperative surgical and anesthesiological variables were analyzed. Results: Operative time was within 90 min (41.1 ± 17.1 mean ± standard deviation (SD)) and no conversion to laparotomy or general anesthesia was required. According to VAS score, the postoperative pain during the whole observation time was less than 3 (mean). Faster resumption of bowel motility (6.5 ± 2.1 mean ± SD) and women's mobilization (3.1 ± 0.7 mean ± SD) were observed as well as low incidence of post-operative nausea and vomit. Early discharge and patient's approval were recorded. Intraoperatively pain score was assessed on Likert scale during all stages. Conclusion: Ultra-low-impact laparoscopy showed to provide a satisfying recovery experience for patients in terms of short hospital stays, cosmetic result, and pain relief, without compromising surgical outcomes. The encouraging results lead us to recruit a greater number of patients to validate our technique as a future well-established produce. [ABSTRACT FROM AUTHOR]

Summary: Background: Nearly half of adult patients undergoing surgery experience moderate or severe postoperative pain. Inadequate pain management hampers postoperative recovery and function and may be associated with adverse outcomes. This multidisciplinary consensus statement provides principles that might aid postoperative recovery, and which should be applied throughout the entire peri‐operative pathway by healthcare professionals, institutions and patients. Methods: We conducted a directed literature review followed by a four‐round modified Delphi process to formulate recommendations for organisations and individuals. Results: We make recommendations for the entire peri‐operative period, covering pre‐admission; admission; intra‐operative; post‐anaesthetic care unit; ward; intensive care unit; preparation for discharge; and post‐discharge phases of care. We also provide generic principles of peri‐operative pain management that clinicians should consider throughout the peri‐operative pathway, including: assessing pain to facilitate function; use of multimodal analgesia, including regional anaesthesia; non‐pharmacological strategies; safe use of opioids; and use of protocols and training for staff in caring for patients with postoperative pain. Conclusions: We hope that with attention to these principles and their implementation, outcomes for adult patients having surgery might be improved. [ABSTRACT FROM AUTHOR]

Chronic postsurgical pain (CPSP) significantly impairs quality of life and poses a substantial healthcare burden, affecting up to a quarter of patients undergoing surgery. Although acute pain is recognised as a predictor for CPSP development, the role of patient experience remains underexplored. This study examines the predictive value of patient experience alongside traditional risk factors for CPSP after orthopaedic surgery. An exploratory analysis was conducted on 294 patients from a multicentre randomised clinical trial comparing continuous perineural analgesia and single-injection nerve block in ambulatory orthopaedic surgeries. Patient experience was assessed using the Evaluation du Vecu de l'Anesthésie Générale (EVAN-G) validated questionnaire. Factors associated with CPSP at 90 days after surgery were identified through univariate and multivariate analyses, incorporating patient-reported outcomes and classical variables. Out of 219 patients with complete data, 63 (29%) developed CPSP at day 90. Multivariate analysis revealed a poor pain experience, as assessed by the pain dimension of EVAN-G on postoperative day 2, as an independent predictor of CPSP (odds ratio 6.45, 95% confidence interval 1.65–25.26, P <0.01). Poor pain experience was associated with an augmented risk of CPSP. This study underscores the role of patient-reported outcomes, specifically the pain experience dimension captured by the EVAN-G scale, in prediction of CPSP 90 days after surgery. It suggests a shift from conventional assessments of pain intensity to a comprehensive understanding of pain experience, advocating for tailored pain management approaches that could reduce chronic pain, thereby improving patient quality of life and functional recovery.

Background There is limited evidence for appropriate postoperative opioid prescribing in autologous breast reconstruction. We sought to describe postoperative outpatient prescription opioid use following discharge after deep inferior epigastric perforator (DIEP) breast reconstruction with and without an educational video. Methods Patients undergoing DIEP reconstruction were given a 28-day postoperative pain and medication logbook from August 2022 to June 2023. Our practice implemented an educational video upon discharge on proper opioid consumption. Descriptive statistics on patient characteristics, intraoperative and postoperative opioid consumption, and outpatient prescription opioid use after discharge were compared between the two cohorts. Results A total of 53 logbooks were completed with 20 patients in the no video cohort and 33 in the video cohort. On average, the days to cessation of opiates was longer in the no video cohort (8.2 vs. 5.1 days, p = 0.003). The average number of oxycodone 5 mg equivalents consumed following discharge was 13.8 in the no video cohort and 7.8 in the video cohort, which was statistically significant (p = 0.01). Overall, the percentage of opioids prescribed that were consumed in the video cohort was 28.3% versus 67.1% in the no video cohort. Conclusion For patients discharging home after DIEP reconstruction, we recommend a prescription for 12 oxycodone 5 mg tablets. With the use of an educational video regarding proper opioid consumption, we were able to reduce the total outpatient opioid use to 5 oxycodone 5 mg tablets following hospital discharge.

Objective: The aim of this study was to report the clinical presentation and treatment outcomes of patients treated for IAAD with and without abdominal aortic aneurysm (AAA) in a single academic institution in South America. Materials and Methods: A retrospective review of all patients with IAAD with or without concomitant AAA between January 2002 and December 2023 from a single academic hospital was performed. Results: Eighteen patients with IAAD were diagnosed of whom 13 (72.2%) were males. Median age was 63 years (range: 43-88 years). Sixteen (88.8%) patients presented with symptoms, and in two (11.1%) asymptomatic patients IAAD was an incidental finding. Ten (55.5%) patients had concomitant abdominal aortic aneurysm (AAA), with a median size of the aneurysm of 49.5 mm (range: 44-66 mm). No statistical differences in baseline characteristics were seen between patients with concomitant IAAD and AAA and patients with only IAAD. Seven (38.8%) patients presented chronic dissection, and 11 (61.1%) patients had acute dissection. Five (27.7%) patients were treated conservatively with blood pressure, pain control, and antiplatelets; endovascular surgery was performed in eight (44.4%) patients and open surgery in five (27.7%) patients. The complication rate was 22.2% (n = 4), and the mortality rate was 0%. Median follow-up was 36 months (range: 6-240 months). Complete remodeling was seen in all patients except two patients who underwent conservative treatment. Of those, one had partial remodeling, and the other no changed. Conclusion: Isolated aortic dissection of the abdominal aorta is an uncommon condition, with acceptable different treatment strategies, from conservative to invasive treatments. Sometimes IAAD can concur with AAA, and when so, invasive treatment might be considered. More studies describing the natural history of AAA and its association with IAAD are warranted, as well as further research reporting long-term outcomes on aortic remodeling after different treatment modalities.

• Pro-inflammatory cytokines are associated with increased acute postoperative pain. • IL-6, IL-8, and IL-13 are protective for CPSP. • Cytokine contributions to pain are dynamic and heterogeneous. • Pro-inflammatory cytokines may contribute to initiation and resolution of post-surgical pain. • Cytokines could serve as predictive and prognostic biomarkers of post-surgical pain. To determine if baseline cytokines/chemokines and their changes over postoperative days 0–2 (POD0-2) predict acute and chronic postsurgical pain (CPSP) after major surgery. Prospective, observational, longitudinal nested study. University-affiliated quaternary children's hospital. Subjects (≥8 years old) with idiopathic scoliosis undergoing spine fusion or pectus excavatum undergoing Nuss procedure. Demographics, surgical, psychosocial measures, pain scores, and opioid use over POD0-2 were collected. Cytokine concentrations were analyzed in serial blood samples collected before and up to two weeks after surgery, using Luminex bead arrays. After data preparation, relationships between pre- and post-surgical cytokine concentrations with acute (% time in moderate-severe pain over POD0-2) and chronic (pain score > 3/10 beyond 3 months post-surgery) post-surgical pain were analyzed using univariable and multivariable regression analyses with adjustment for covariates and mixed effects models were used to associate longitudinal cytokine concentrations with pain outcomes. Analyses included 3,164 repeated measures of 16 cytokines/chemokines from 112 subjects (median age 15.3, IQR 13.5–17.0, 54.5 % female, 59.8 % pectus). Acute postsurgical pain was associated with higher baseline concentrations of GM-CSF (β = 0.95, SE 0.31; p = 0.003), IL-1β (β = 0.84, SE 0.36; p = 0.02), IL-2 (β = 0.78, SE 0.34; p = 0.03), and IL-12 p70 (β = 0.88, SE 0.40; p = 0.03) and longitudinal postoperative elevations in GM-CSF (β = 1.38, SE 0.57; p = 0.03), IFNγ (β = 1.36, SE 0.6; p = 0.03), IL-1β (β = 1.25, SE 0.59; p = 0.03), IL-7 (β = 1.65, SE 0.7; p = 0.02), and IL-12 p70 (β = 1.17, SE 0.58; p = 0.04). In contrast, CPSP was associated with lower baseline concentration of IL-8 (β = -0.39, SE 0.17; p = 0.02), and the risk of developing CPSP was elevated in patients with lower longitudinal postoperative concentrations of IL-6 (β = -0.57, SE 0.26; p = 0.03), IL-8 (β = -0.68, SE 0.24; p = 0.006), and IL-13 (β = -0.48, SE 0.22; p = 0.03). Covariates female (vs. male) sex and surgery type (pectus surgery vs. spine) were associated with higher odds for CPSP in baseline adjusted cytokine-CPSP association models for IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, TNFα, and IL-8, IL-10, respectively. We identified pro-inflammatory cytokine profiles associated with higher risk of acute postoperative pain. Interestingly, pleiotropic cytokine IL-6, chemokine IL-8 (which promotes neutrophil infiltration and monocyte differentiation), and monocyte-released anti-inflammatory cytokine IL-13, were associated with lower CPSP risk. Our results suggest heterogenous outcomes of cytokine/chemokine signaling that can both promote and protect against post-surgical pain. These may serve as predictive and prognostic biomarkers of pain outcomes following surgery. [ABSTRACT FROM AUTHOR]

The relationship between perioperative temperatures and postoperative pain is unknown. The present study investigated the relationship of intraoperative hypothermia and perioperative opioid requirements after immediate implant-based breast reconstruction. A retrospective chart review was conducted on patients undergoing immediate implant-based breast reconstruction from 2019–2023. Patients were classified into the hypothermic group (majority of procedure <36.0 °C) or normothermic group (majority of procedure ≥36.0 °C). Cumulative inpatient opioid requirements (morphine milli-equivalents [MMEs]) and frequency of patients requiring "high-dose opioids" (≥100 MMEs) were collected and compared between the groups. In total, 536 patients (835 breasts) were included, among whom 135 (25.1%) were hypothermic. The hypothermic group had lower mean intraoperative (88.4 vs. 99.1 MMEs, P = 0.007) and postoperative (45.6 vs. 56.8 MMEs, P = 0.006) than the normothermic group. Mean (B = 14.6, P = 0.004) and nadir (B = 10.4, P = 0.038) intraoperative temperatures directly predicted higher opioid requirements while higher percentages of the procedure time spent under 36 °C (B = −27.6, P = 0.004) predicted lower opioid requirements. The hypothermic group was associated with 66% decreased odds of requiring high-dose opioids after adjusting for differences in patient and operative characteristics (P = 0.007). Hypothermia is associated with decreased perioperative opioid requirements. Future studies should further investigate ideal temperature thresholds for warming protocols to minimize postoperative pain. [ABSTRACT FROM AUTHOR]

Background: With the increased use of robotic surgery, robotic transabdominal preperitoneal repair (R-TAPP) has become a commonly used approach for inguinal hernia repair. The laparoscopic totally extraperitoneal repair (L-TEP) has the advantage of not entering the peritoneal cavity; however, it has greater technical difficulty. Robotic surgery has demonstrated superiority over laparoscopy in many surgical settings, but there is limited evidence comparing L-TEP and R-TAPP. Methods: This was a retrospective review of patients who underwent L-TEP and R-TAPP at Baylor University Medical Center between December 2011 and January 2022. Information on patient demographic characteristics, comorbidities, postoperative complications, hospital length of stay, and postoperative complications requiring a procedure was collected. Results: A total of 298 patients were analyzed; 245 underwent R-TAPP and 53 underwent L-TEP. Hernia recurrence was significantly decreased in those who underwent R-TAPP (1.2%) compared to L-TEP (9.4%) (P = 0.01). Postoperative pain was also significantly decreased in the R-TAPP group (5.3%) as compared to the L-TEP group (13.2%) (P = 0.01). Conclusions: With the transition from L-TEP to R-TAPP over recent years, there is limited evidence supporting this change in practice. Our single-center retrospective review demonstrates that R-TAPP is noninferior to L-TEP and has significantly decreased hernia recurrence. [ABSTRACT FROM AUTHOR]

Background: The primary aim of our study was to determine which patient characteristics were associated with opioid consumption following cesarean delivery. Methods: The Baylor Scott & White Research Institute institutional review board approved this study (024-178). Patients who underwent cesarean delivery at Baylor Scott & White Medical Center – Temple with single injection or combined spinal epidural anesthesia in 2023 were eligible for inclusion. We examined the medical records of 300 patients, calculated the 24-hour opioid consumption for each, and compared the top third to the low group in a bivariate analysis and then performed a multivariate logistic regression. Results: One hundred thirty-one patients had no opioid consumption in the first 24 postoperative hours, and 100 patients had a morphine milligram consumption of 30 to 117.5 mg. A multivariate logistic regression determined that patients in the higher opioid consumption cohort were more likely to have received combined spinal epidural anesthesia (odds ratio 2.079; 95% confidence interval 1.149, 3.762; P = 0.02) and administration of intravenous dexmedetomidine in the intraoperative period (odds ratio 2.542; 95% confidence interval 1.038, 6.224; P = 0.04). Conclusion: Intraoperative administration of intravenous dexmedetomidine and combined spinal epidural anesthesia was associated with increased postoperative opioid consumption following cesarean delivery.

Background Acetabular dysplasia (AD) causes pain, limited function, and development of early hip osteoarthritis. Periacetabular osteotomy (PAO) is a surgical treatment for AD that aims to reposition the acetabulum to reduce pain and improve function. Purpose To examine pain recovery and physical activity (PA) before and during the six months after PAO. Study Design Case series, prospective Methods Individuals with AD scheduled for PAO were enrolled. Pain intensity was evaluated before PAO and at one week and one, three, and six months following PAO. PA levels was evaluated before and six months following PAO using accelerometers (time spent in sedentary behavior, light PA, moderate-to-vigorous PA [MVPA], and daily steps) and the International Physical Activity Questionnaire (IPAQ; time spent in walking and in MVPA). Pain improvements was examined over time following PAO using a repeated-measures one-way ANOVA as well as improvements in PA levels before and six months after PAO using paired-sample t tests. In addition, time spent in MVPA was qualitatively summarized at each time point (before and six months after PAO) measured by both the accelerometers and IPAQ. Results Out of 49 screened participants, 28 were enrolled, and 23 individuals (22 females; age=23.1±7.9 years) completed both study visits. Compared to pre-PAO pain, participants reported significant improvements in pain at one month and onward following PAO (p<0.011). However, PA levels at six months following PAO did not differ from pre-PAO PA levels (p>0.05). Qualitatively, participants reported spending more time in MVPA recorded by the IPAQ (pre-PAO=73.3±150.2 mins/day; six-months after PAO=121.2±192.2 mins/day), compared with MVPA recorded by accelerometers (pre-PAO=22.6±25.2 mins/ day; six-months after PAO=25.0±21.4 mins/day). Conclusions Individuals with AD reported significant pain reduction at one month and up to six months after PAO, but PA levels did not change six months after PAO compared to baseline testing. Future studies should consider examining longitudinal pain recovery and PA improvements over longer periods of time with larger samples of individuals with AD undergoing PAO and identifying modifiable factors to minimize pain and increase PA participation.

Introduction: Ambulatory hip arthroscopies are associated with moderate-to-severe pain often requiring opioid analgesia. Novel motor-sparing blocks, the pericapsular nerve group (PENG) and lateral femoral cutaneous nerve (LFCN) block, have shown efficacy in hip surgery. Purpose: We sought to investigate the analgesic benefits of these novel blocks in terms of opioid-sparing and discharge efficiency. Methods: We conducted a retrospective cohort study with propensity score matching of 224 patients who underwent ambulatory elective unilateral hip arthroscopy. One group received a combined PENG and LFCN block (PENG/LFCN, n = 86), while a second group received only a PENG block (n = 26). A control group (n = 112) received no blocks. The primary outcome was postanesthesia care unit (PACU) mean opioid consumption. Secondary outcomes were maximum numeric rating scale (NRS) pain score, intravenous rescue analgesia, and PACU readiness-for-discharge times. Results: The PENG/LFCN-block group required significantly less opioids than the control group in the PACU (25.98 ± 13.04 vs 14.58 ± 5.77, respectively) and were discharged earlier 2.72 ± 1.16 vs 4.42 ± 1.63 hours, respectively). The combined PENG/LFCN group also used less intravenous rescue opioids than the control group (0.47 ± 1.18 vs 1.44 ± 2.1 mg, respectively) and showed a significant difference in the highest NRS pain scores than the control group (6.01 ± 2.38 vs 6.77 ± 2.1 respectively). The PENG block alone group did not show a significant difference in opioid reduction (21.95 ± 15.83 vs 27.72 ± 15.01, respectively). Conclusions: This retrospective study found that in patients who underwent ambulatory elective unilateral hip arthroscopy, a combined PENG and LFCN block was associated with expedited PACU discharge and a clinically significant reduction in postoperative opioid use. Further study is warranted. [ABSTRACT FROM AUTHOR]

Objective: To evaluate patients' satisfaction with opioid versus opioid‐sparing postoperative analgesia in patients undergoing outpatient head and neck surgery. Study Design: Prospective randomized trial. Setting: Tertiary care academic hospital. Methods: Adult patients undergoing outpatient head and neck surgery were randomly assigned to 1 of 3 analgesic regimens. First‐ and second‐line medications were the following by group (1) Hydrocodone‐acetaminophen with ibuprofen, (2) ibuprofen with hydrocodone‐acetaminophen, and (3) ibuprofen with acetaminophen. Preoperative counseling was provided to patients regarding expected pain and proper medication use. Postoperative questionnaires were administered to assess satisfaction. Results: One hundred three patients were enrolled in the study (mean age, 56.5 years; women, 75 [73%]). The mean satisfaction score with the pain regimen assigned was similar between the 3 groups (scale 0‐10, [7.7, 8.3, 8.5, P =.46]). A similar percentage of patients in each group reported that surgery was more painful than anticipated (25%, 32%, 26%, P =.978), and a similar percentage of patients reported willingness to utilize the same analgesic regimen following future surgeries (75%, 83%, 76%, P =.682). Additional questions evaluating the side effect profile, maximum and minimum pain scores, and difficulty of recovery were not statistically different between the 3 groups. Conclusion: In the postoperative population for outpatient head and neck surgeries, there was no significant difference in patient satisfaction and pain control between the opioid and nonopioid arms. Providers should discuss opioid‐sparing regimens preoperatively with patients and describe them as effective in providing adequate pain control without a significant impact on patient's perception of care.

Background: Acute pain is a major concern after arthroscopic shoulder surgery, supraclavicular brachial plexus blockade has shown favorable postoperative analgesic effects. However, its duration of analgesia does not meet clinical needs. We aimed to explore whether the combination of different local anesthetic adjunct can prolong the analgesic duration of supraclavicular brachial plexus block for arthroscopic shoulder surgery. Methods: In this prospective randomized controlled trial, we allocated 80 patients into four groups: Group DMD (dexamethasone 10 mg + ropivacaine 100 mg + dexmedetomidine 50 µg + magnesium sulfate 250 mg), Group DM (ropivacaine 100 mg + dexmedetomidine 50 µg + magnesium sulfate 250 mg), Group M (ropivacaine 100 mg + magnesium sulfate 250 mg) and Group D (ropivacaine 100 mg + dexmedetomidine 50 µg). The primary outcome was the time to first request for analgesia. Secondary outcome measures included cumulative opioid consumption at 6, 12, 18, 24, and 48 h postoperatively, VAS scores at 6, 12, 18, 24, and 48 h postoperatively and so on. Results: The time to first request for analgesia in Group DMD was significantly longer than Group DM (P = 0.011) and Group M (P = 0.003). The cumulative opioid consumption at 18 h postoperatively in Group DMD was significantly lower than in Group DM (P = 0.002) and Group M (P = 0.007). The cumulative opioid consumption at 24 h postoperatively in Group DMD was significantly lower than in Group DM (P = 0.016). The VAS score at 6 h postoperatively in Group DMD was significantly lower than in Group DM and Group M. The VAS score at 12 h postoperatively in Group DMD was significantly lower than in Group M. For American Shoulder and Elbow Surgeons Score, Group DMD had a better score than Group DM and Group D. Conclusions: The analgesic efficacy of supraclavicular brachial plexus blockade combined with dexamethasone, magnesium sulfate, and dexmedetomidine is significantly superior to the combination of magnesium sulfate and dexmedetomidine, and significantly superior to the use of magnesium sulfate alone.

Background: Elderly patients often experience severe pain during percutaneous kyphoplasty under local anaesthesia. The aim of this work was to evaluate the effect of lidocaine combined with esketamine on pain improvement in elderly patients receiving local anaesthesia via percutaneous kyphoplasty. Methods: This prospective, randomized comparative trial was conducted on 66 elderly patients, aged 60–80 years, with an American Society of Anaesthesiologists (ASA) grade of I-III, I‒III and a BMI of 18.5–25 kg/m2, who underwent single-level lumbar percutaneous kyphoplasty under local anaesthesia. Patients were divided into two equal groups (33 per group). Group LE received 200 mg of 1% lidocaine and 25 mg of esketamine (total volume of 20 ml), and Group L received 200 mg of 1% lidocaine (total volume of 20 ml). Patient characteristics, surgery, VAS scores, MAP, HR, MOAA/S scores, patient satisfaction and related adverse reactions were compared for the groups. The VAS scores during and after surgery were considered the primary outcome. Results: There were statistically significant differences in the VAS score between the two groups at the following time points: channel establishment by the puncture needle, balloon dilation, bone cement injection and postoperative period (P < 0.05). The VAS score decreased in the LE group, but the MAP and HR were more stable, and the difference was statistically significant (P < 0.05). The difference in the MOAA/S score between the two groups was statistically significant (P < 0.05), and the MOAA/S score in the LE group decreased. The patient satisfaction level in the LE group was 100% and 48.48% in the L group (P < 0.05). There were no related complications or adverse reactions in either group. Conclusion: The application of lidocaine combined with esketamine in local episcopal percutaneous vertebral kyphoplasty in elderly patients not only provides an effective analgesic effect but also improves surgical safety and patient comfort, which has important clinical value in promoting the optimization of surgical anaesthesia management in elderly patients.

Background: Postoperative pain management remains a significant challenge for patients undergoing posterior urethroplasty (PU). In a previous study, we proposed a novel technique of combined pudendal nerve (PN) and spermatic cord (SC) block to manage pain after PU. The present trial was conducted to test the hypothesis that this technique is effective for pain control after PU and provides longer-lasting analgesia than caudal epidural block (CB). Methods: Sixty patients undergoing PU were randomized into two groups: Group NB received combined PN and SC block, and Group CB received CB. General anesthesia with a laryngeal mask was performed. The primary outcome was the postoperative analgesic duration, and the secondary outcomes included the Numeric Rating Scale (NRS) scores for pain and the number of patients with different motor scores of the lower limb at 3, 6, 12, and 24 h postoperatively. Results: Two patients in Group CB were withdrawn due to block failure. The postoperative analgesic duration was statistically longer in Group NB compared with Group CB (mean difference [95% confidence interval], 115.78 min [17.80, 213.75]; P = 0.021). The NRS scores for pain at 12 and 24 h after surgery were statistically lower in Group NB compared with Group CB. Group NB had statistically more patients with motor score 0 at 3 h postoperatively than Group CB. Conclusions: PN combined with SC block is an effective technique for postoperative analgesia in PU. This technique can achieve a longer duration of analgesia and lower pain scores, especially 12 h after surgery, than a CB.

Background: Closed suction drainage is typically used in orthopaedic surgery to reduce the occurrence of incision complications. However, whether drainage tubes should be routinely placed in iliac crest bone graft surgeries is still unclear. This study aimed to evaluate the effect of closed suction drainage at iliac crest bone donor site on clinical prognosis. Materials and methods: G.Power was used for a prior analysis to estimate the required sample size. 91 patients with tibial plateau fractures who underwent iliac crest harvesting and grafting between January 2019 and January 2022 were enrolled in the study. All surgeries were performed by the same experienced surgeon team. Patients were divided into close suction drainage (CSD) group and no-CSD group according to the use of drainage tube. The demographic and perioperative data of the patients were collected and analyzed. Results: There were no significant differences in demographic characteristics between the two groups except that the CSD group had more people with diabetes. The use of closed suction drainage in patients undergoing iliac crest harvest can significantly reduce the incidence of incision complications without increasing pain level and extending hospital stay. However, the closed suction drainage obviously caused the increase of blood loss. More drainage tubes would cause more drainage fluid to flow out. And drainage tube placement may impose a higher financial burden on patients. Conclusion: The closed suction drainage should not be recommended routinely for iliac crest bone graft patients. Only when the patient is at high risk for infection and without severe blood loss, placing a single drainage tube is recommended. Trial registration: This study was registered at (NCT04807062) and approved by the Ethics Committee of the participating institution (Theoretical No. 2015-003-1). [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Material and Methods Results Conclusions The present trial evaluated the first‐time application of autogenous demineralized dentin graft with injectable platelet‐rich fibrin (ADDG + i‐PRF) versus autogenous demineralized dentin graft (ADDG), in alveolar ridge preservation (ARP) in the maxillary aesthetic zone.Twenty‐two maxillary (n = 22) non‐molar teeth indicated for extraction were randomized into two groups (n = 11/group). Extracted teeth were prepared into ADDG, implanted into extraction sockets with or without i‐PRF amalgamation and covered by collagen sponge. Cone‐beam computed tomography scans at baseline and 6 months were compared to assess ridge‐dimensional changes. Keratinized tissue width, patient satisfaction, pain score and chair time were recorded. In the course of dental implant placements at 6 months, bone core biopsies of engrafted sites were obtained and analysed histomorphometrically.Reduction in ridge width was 1.71 ± 1.08 and 1.8 ± 1.35 mm, while reduction in ridge height was 1.11 ± 0.76 and 1.8 ± 0.96 mm for ADDG + i‐PRF and ADDG, respectively (p > 0.05). Significant differences in keratinized tissue width reduction were notable between ADDG + i‐PRF and ADDG (0.12 ± 0.34 and 0.58 ± 0.34 mm respectively; p = 0.008). Postoperative pain scores were significantly lower in ADDG + i‐PRF (p = 0.012). All patients in the two groups were satisfied with no differences in chair time (p > 0.05). No differences in total percentage area of newly formed bone, soft tissue or graft particles were observed between the groups (p > 0.05).ADDG alone or in combination with i‐PRF yields similar results regarding ARP clinically, quality of the formed osseous tissues, as well as patients' satisfaction. Yet, the addition of i‐PRF to ADDG tends to preserve the keratinized tissue and lessen postoperative pain. [ABSTRACT FROM AUTHOR]

Background: This clinical study aims to compare postoperative pain after single-visit root canal treatment of teeth with asymptomatic apical periodontitis using epoxy-resin-based AH Plus and calcium silicate-based Endosequence BC sealers with or without sonic activation. Methods: This study included 72 individuals with one first or second mandibular premolar tooth with asymptomatic apical periodontitis. They were randomly divided into four groups according to the root canal sealer (AH Plus or Endosequence BC) and activation protocol (sonic activation or non-activation) (n = 18). The participants were ask to rate their postoperative pain intensity on a NRS scale as none, minimal, moderate, or severe after 24 h, 48 h, 72 h, and 7 days following treatment. Patients were also asked to record the number of prescribed analgesic medication tablets (400 mg of ibuprofen) taken. Statistical analysis were performed using the Mann-Whitney U test, the Friedman test, the Spearman's correlation test, the Chi-square test. Significance level was established at 0.05. Results: There was no statistically significant difference in postoperative pain scores or analgesic intake between AH Plus and Endosequence BC sealers regardless of the activation protocol (p > 0.05). There was no statistically significant difference in postoperative pain scores between the sonic activation and non-activation groups (p > 0.05). A weak positive correlation was detected between Endoactivator sonic activation and sealer extrusion (r = 0.36). Conclusions: AH Plus and EndoSequence BC root canal sealers showed similar results in terms of prevalance and intensity of postoperative pain. Sonic activation and non-activation groups had similar postoperative pain scores. Clinical trial registration: The study was retrospectively registered with ClinicalTrials.gov (NCT06403293).

Introduction: Individuals with limb loss frequently report post-amputation phenomena, including nonpainful phantom sensations, phantom limb pain (PLP), and residual limb pain (RLP). Although post-amputation pain is common, not all patients benefit from widely accepted treatments. A greater understanding of phantom limb "telescoping", the experience of one's phantom hand or foot gradually approaching the residual limb, may assist in developing more effective interventions for reducing post-amputation pain. This case report explores the relationships between PLP, RLP, telescoping, and psychosocial experience in one person with a lower limb amputation. The aim of this case is to illustrate one possible relationship between telescoping and PLP as the mechanisms linking the two remain equivocal. Methods: The participant is a 35-year-old male who underwent a transfemoral amputation due to a traumatic injury to his right leg approximately 4 years prior. He responded to questionnaires evaluating demographic and healthrelated information (e.g., age, sex, marital status, reason for amputation), pain and psychological variables via the Brief Pain Inventory (BPI-SF), ID Pain Questionnaire (IDPQ), Pain Catastrophizing Scale (PSC-4), Patient Health Questionnaire-4 (PHQ-4), Life Orientation Test-Revised (LOT-R), Connor-Davidson Resilience Scale (CD-RISC2), and Chronic Pain Acceptance Questionnaire (CPAQ-8) and telescoping, measured by a newly developed app. The participant completed a semi-structured interview that was designed to ascertain patterns in the overlapping experience of phantom limb telescoping and post-amputation pain. Results: The participant rated his average PLP as 10 on a Numeric Rating Scale (NRS) from 0 ("no pain") to 10 ("worst pain imaginable") shortly after amputation. Approximately 12 months later, the participant noticed a shortening of his phantom limb, with a concurrent decrease in PLP. At present, his average NRS pain intensity is a 5/10. The participant described how the daily, debilitating PLP intensity diminished to weekly, manageable pain over time. Most notably, his responses on questionnaires were consistent with neuropathic PLP, mild to moderate levels of pain interference, a high level of catastrophic thinking about pain, low optimism, and mild symptoms of anxiety and depression. Discussion: In this report, telescoping appeared to be preceded by an initial reduction in PLP intensity but these findings are based on a single case report and must be replicated with a large sample size before we have a clearer idea of the relationship between telescoping and PLP. This study provides insight into factors that may maintain PLP, generating targets for further investigation. [ABSTRACT FROM AUTHOR]

Background: This prospective cohort study focused on the predictive value of frailty or pre-frailty assessed by Edmonton Frailty Scale (EFS) for postoperative delirium in spinal surgery patients. Methods: The primary outcome measurement was postoperative delirium (POD) evaluated by Confusion Assessment Method at day 1, day 2, and day 3 after the surgery. Secondary outcomes included severity and duration of POD, severe postoperative pain measured by Faces Pain Scale-Revised. Patients scheduled for elective spinal surgery were enrolled and assessed for frailty by EFS before surgery. Demographic data, preoperative, intraoperative, and postoperative information were collected. Results: 231 out of 325 patients were enrolled and analyzed in this study at last. The cohort with 36.8% being frail and 28.5% being vulnerable. Postoperative delirium was detected in 41 in 231 patients. Multivariate logistic regression analysis revealed that vulnerable to frailty (OR = 4.681, 95% CI: 1.199 to 18.271, P = 0.026), after adjusted duration of surgery more than 3 h, using flumazenil at the end of surgery, using butorphanol only in postoperative patient-controlled intravenous analgesia, moderate-to-severe pain at day 1 and 2, is a strong predictor of postoperative delirium. Frailty was associated with longer duration (frailty vs. fit, P = 0.364) and stronger severity of postoperative delirium in the first two days (P < 0.001). High EFS score was independent risk factor of severe postoperative pain (Frailty vs. Fit: OR = 5.007, 95% CI: 1.903 to 13.174, P = 0.001; Vulnerable vs. Fit: OR = 2.525, 95% CI: 1.008 to 6.329, P = 0.048). In stratified tests, Sufentanil regimen in intravenous PCA significantly increase the proportion of POD in vulnerable group (P = 0.030), instead of frailty group (P = 0.872) or fit group (P = 0.928). Conclusions: Frailty can increase the risk, severity, duration of delirium and severe postoperative pain in the first 3 days after surgery of patients. Trial registration: The protocol of this study has been approved by the Ethic Committee of Shanghai Changzheng Hospital (Approval file number: 2022SL044) and informed consent was obtained from all the patients.

Background: The effectiveness of the quadratus lumborum block (QLB) for postoperative pain management depends on the injection pathway used. There is limited research on the block area produced by intramuscular injection of local anesthesia in the quadratus lumborum muscle. This study aimed to determine the cutaneous sensory blockade area produced by an intramuscular quadratus lumborum block (QLBi) at the L2 level. Methods: Twenty patients aged 18–60 years with ASA grade I-II and a BMI of 18–30 kg/m2 who were scheduled for open inguinal hernia repair with mesh underwent ultrasound-guided QLBi injection of 20 ml of 0.5% ropivacaine. The cutaneous sensory blockade area was measured by applying a cold stimulus 1 h after the block and then measured every hour after surgery until the sensation returned to normal. The duration of a blockade is defined as the time it takes for all affected areas to fully regain normal sensation following a blockade. Pain scores (numeric rating scale, NRS) were recorded at 2, 4, 8, 12, and 24 h after surgery. Adverse reactions to QLBi were recorded 24 h after surgery. Results: All 20 patients had reduced or lost cold sensation areas. The greatest extent of cold sensation reduction occurred at T7 (10%), and the least amount of cold sensation reduction occurred at L3 (10%). The block level covered T8 (20%), T9 (30%), T10 (45%), T11 (90%), T12 (95%), L1 (100%), and L2 (15%). Eighteen patients experienced areas of sensory loss, with the highest range at T11 and the lowest at L2. The duration of the blockade was 8.9 ± 3.8 h, with a maximum of 24 h and a minimum of 5 h. One patient experienced quadriceps weakness after surgery. Conclusion: Quadratus lumborum block of intramuscular pathway can produce effective cutaneous sensory blockade, which can be used for postoperative analgesia of indirect inguinal hernia operation, and may also be beneficial to analgesia of other lower abdominal operations. However, the best method needs further confirmation to determine specific anesthesia methods for various operations. Chinese clinical trial registry: June 2, 2018; ChiCTR1800016457.

The aim of the study was to compare the analgesic efficacy of butorphanol and lidocaine, alone or in combination, in calves undergoing surgical repair of umbilical hernia. The study was conducted in 60 calves of different breeds. Xylazine 0.3mg/kg was administered intramuscularly to all animals in the study. The animals were then divided into three groups (n = 20) that received different treatments with lidocaine at 4.5mg/kg and butorphanol at 0.02mg/kg. The L group received lidocaine both by infiltration of the surgical planes and intraperitoneally, the B group received butorphanol both by infiltration of the surgical planes and intraperitoneally, and finally the LB group received lidocaine by infiltration of the surgical planes and butorphanol intraperitoneally. Heart and respiratory rates, haemoglobin oxygen saturation, non-invasive blood pressure and temperature were recorded during surgery. Response to the surgical stimulus was scored on a cumulative numerical scale that included percentage changes in HR, RR and SAP. Postoperative pain was assessed by three independent observers, blinded to treatment, using the UNESP-Botucatu Unidimensional Composite Pain Scale (UNESP-Botucatu UCPSIV) for the assessment of postoperative pain in cattle. The course of physiological variables was appropriate for patients under anaesthesia. No subject required rescue intraoperative analgesia. In group L, 4 subjects at 40m and 5 subjects at 50m required postoperative rescue analgesia. Both butorphanol alone and the combination of butorphanol and lidocaine showed excellent intraoperative and postoperative scores. Furthermore, this combination did not cause any cardiopulmonary or other adverse effects. Based on the results of this study, both butorphanol alone and the coadministration of butorphanol and lidocaine administered locally proved to be safe and effective in providing adequate and long-lasting analgesia in calves, helping to reduce postoperative discomfort and maintaining adequate animal welfare.

Objective To observe the application effect of bupivacaine liposome transversus abdominis plane block (TAPB) on postoperative pain and stress response in patients undergoing laparoscopic gynecological surgery. Methods Totally 120 patients undergoing laparoscopic gynecological surgery were randomly divided into two groups： the bupivacaine liposome group (LB group) and the ropivacaine group (L group) . Patients in the LB group received bupivacaine liposome TAPB before the start of the surgery, while patients in the L group received an equivalent dose of ropivacaine TAPB. Postoperative pain was assessed by using the Numerical Rating Scale (NRS) at 6 h (T1), 24 h (T2), 48 h (T3), 60 h (T4), and 72 h (T5) for 72 consecutive h after surgery, with the number of analgesic pump button presses and rescue analgesia requirements recorded. Additionally, venous blood was drawn from patients before operation (D0) and on the 1st (D1), 3rd (D3), and 7th (D7) days after surgery, and the serum levels of cortisol, interleukin-6(IL-6), and tumor necrosis factorα(TNF-α) were measured. The Quality of Recovery-40(QoR-40) scale was used to assess the quality of recovery at 24, 48, and 72 h postoperatively, and we recorded the postoperative nausea and vomiting (PONV), urinary retention, pruritus and incision infection in the two groups. Results NRS scores significantly decreased over time in both groups (all P< 0.05) . The NRS scores at T2 to T4 in the LB group were lower than those of the L group (all P<0.05) . The number of postoperative remedial analgesia and the number of analgesic pump button presses in the LB group were smaller than those in the L group (all P<0.05) . The levels of serum cortisol, IL-6, and TNF-α in both groups showed a trend of first increasing and then decreasing after surgery. The levels of serum cortisol, IL-6, and TNF-α on the 3rd day after surgery in the LB group were lower than those in the L group (all P<0.05) . The QoR-40 scores increased over time in both groups, with a more significant increase in the LB group (P<0.05) . The incidence of PONV was lower in the LB group than in the L group (P<0.05), while there were no significant differences in the occurrence of urinary retention, pruritus, or incision infection between the two groups (all P>0.05) . Conclusion Bupivacaine liposome TAPB showed a long-lasting analgesic effects in laparoscopic gynecological surgery and could reduced postoperative stress response, improve the quality of postoperative recovery and had high safety.

Objective: This study compared the efficacy of ultrasound-guided erector spinae plane block (ESPB) and wound infiltration (WI) for postoperative analgesia in patients who underwent lumbar spinal surgery with instrumentation. Methods: In this randomized controlled trial, 80 patients were divided into two groups: ESPB (n = 40) and WI (n = 40). Postoperative pain intensity was assessed via the visual analog scale (VAS) at multiple time points within 24 h. Additionally, opioid consumption, time to first rescue analgesia, incidence of postoperative nausea and vomiting (PONV), and patient satisfaction were evaluated. Results: Both ESPB and WI provided effective postoperative pain management, with no significant differences in VAS scores. However, the ESPB group demonstrated a significantly longer duration of analgesia, a shorter time to first rescue analgesia, and lower total tramadol consumption (50 ± 60 mg vs. 100 ± 75 mg; p = 0.010) than did the WI group. Furthermore, a trend toward reduced PONV incidence was observed in the ESPB group, likely due to its opioid-sparing effect. Conclusion: While both ESPB and WI provided effective postoperative pain management, ESPB demonstrated a distinct advantage by offering a longer duration of analgesia and significantly reducing opioid consumption. These findings suggest that ESPB is more effective than WI for postoperative analgesia in lumbar spinal surgeries, providing prolonged pain relief and improving patient outcomes. Further studies are warranted to explore its long-term benefits and cost-effectiveness. Trial Registration: ClinicalTrials.govPRS: NCT06567964 Date: 08/21/2024 Retrospectively registered. Key Points: 1. Study Objective: This study aimed to compare the efficacy of ultrasound-guided erector spinae plane block (ESPB) with that of wound infiltration (WI) for postoperative analgesia in lumbar spinal surgeries involving instrumentation. 2. Primary outcome: Postoperative pain intensity was measured via the visual analog scale (VAS) at multiple time points. The VAS scores were comparable between ESPB and WI at all assessed time points, indicating no significant differences in pain scores. However, both techniques still played a role in postoperative pain management. 3. Opioid consumption: ESPB was associated with a significant reduction in total tramadol consumption compared with WI, indicating that an opioid-sparing effect that could reduce the risk of opioid-related side effects. 4. Duration of Analgesia: Patients in the ESPB group experienced a longer duration before requiring rescue analgesia, suggesting that ESPB provides more prolonged pain relief than WI does. 5. Side Effects and Patient Satisfaction: The incidence of postoperative nausea and vomiting (PONV) was lower in the ESPB group, potentially due to reduced opioid consumption. These findings suggest that ESPB may increase patient satisfaction and comfort during the postoperative period. 6. Clinical Implications: These findings support the integration of ESPB into multimodal analgesia protocols for lumbar spinal surgeries, given its potential advantages in reducing opioid consumption and providing extended pain relief. 7. Limitations: This study has several limitations. First, although the sample size was calculated based on a power analysis and was sufficient to detect significant differences in the primary outcomes, a larger sample size might provide more robust insights into secondary outcomes or less common side effects. Additionally, the study was conducted at a single center, which may limit the generalizability of the findings. Future multicenter studies are needed to validate these results across diverse patient populations and clinical practices. Lastly, the follow-up period was limited to 24 h, which does not allow for the assessment of long-term outcomes such as chronic pain development or functional recovery. 8. Future research: Further studies are recommended to explore the long-term benefits of ESPB, its cost-effectiveness, and its potential integration into enhanced recovery protocols (ERASs) for surgical patients.

Objective: Currently, the primary surgical treatment for pseudomyxoma peritonei (PMP) is cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC). The perioperative period is frequently accompanied by severe pain. Erector spinae plane block (ESPB) can enhance analgesia for abdominal surgery. The purpose of this study was to compare the analgesic effects of bilateral multiple-injection ESPB in patients with PMP. Methods: Fifty patients with PMP were randomly divided into two groups: the ESPB combined with general anesthesia group (Group E) and the general anesthesia alone group (Group C). Prior to the induction, patients in Group E underwent ESPB at the T7 and T11 levels. The primary outcome was the visual analog scale (VAS) scores during rest at 6 h post-extubation. Secondary outcomes included intraoperative and postoperative opioid consumption, time for first rescue analgesia, frequency distribution of rescue analgesia, incidence of nausea and vomiting, adverse events associated with ESPB. Results: The Visual Analogue Scale (VAS) scores in Group E were significantly lower compared to Group C at immediate post-extubation (1.6 ± 0.9 vs. 2.4 ± 1.2, P = 0.008), and at 2 (1.9 ± 1.2 vs. 3.2 ± 1.1, P < 0.001), 4 (2.4 ± 1.5 vs. 3.7 ± 1.0, P = 0.001), and 6 h (2.7 ± 1.1 vs. 3.8 ± 1.4, P = 0.004) post-extubation during rest. Similarly, the VAS scores in Group E were significantly lower than those in Group C at immediate post-extubation (3.0 ± 1.4 vs. 4.6 ± 1.2, P < 0.001), and at 2 (3.8 ± 1.7 vs. 4.9 ± 1.4, P = 0.019), 4 (3.5 ± 1.3 vs. 5.3 ± 1.5, P < 0.001), and 6 h (3.9 ± 1.8 vs. 4.9 ± 1.3, P = 0.004) post-extubation during movement. In Group E, the intraoperative remifentanil administration (2319.3 ± 1089.5 vs. 2984.6 ± 796.1, P = 0.017) and the amount of rescue analgesia within 2 h post-extubation (0 vs. 4, P = 0.037) were significantly less than in Group C, and the first rescue analgesia time was shorter as well (231.4 ± 147.5 vs. 668.8 ± 416.7, P < 0.001). Conclusion: Compared to general anesthesia alone, bilateral multiple-injection ESPB with 0.2% ropivacaine can enhance analgesia and reduce opioid administration in patients with PMP. However, the duration of analgesia with ESPB is relatively short due to the low concentration of the local anesthetic used.

Introduction Methods Results Conclusion Registration The erector spinae plane block (ESPB) has recently emerged as a regional anesthesia technique for perioperative pain management in pediatric cardiac surgery. However, evidence comparing its effectiveness with intravenous (IV) opioid‐based analgesia is limited. We aimed to evaluate and compare the analgesic efficacy of ESPB versus IV opioids in this setting.We systematically reviewed and meta‐analyzed studies comparing ESPB with IV opioid analgesia in pediatric cardiac surgeries with midline sternotomy. Primary outcomes were intraoperative fentanyl consumption and intensive care unit (ICU) length of stay (LOS). Secondary outcomes included postoperative opioid consumption, time to first rescue analgesia, pain scores, postoperative vomiting and other complications, extubation time, and hospital LOS. Statistical analyses were performed using RStudio version 4.2.3.Five studies with 384 patients were included, with 178 receiving ESPB. ESPB significantly reduced intraoperative fentanyl use (MD −1.90 μg.kg−1; 95% CI −3.15 to −0.66 μg.kg−1; p = .003; I2 = 58%) and ICU LOS (MD ‐3.50 h; 95% CI ‐4.32 to −2.69 h; p < .0001; I2 = 0%). No significant differences were found in the remaining outcomes.Our findings suggest the ESPB might be an important adjunct to enhancing analgesia for midline sternotomies in pediatric cardiac surgery, potentially reducing intraoperative opioid requirements and ICU LOS.CRD 42024526961.

ABSTRACT Objective Methods Results Conclusion Despite being well‐studied and widely utilized, the efficacy of cryotherapy after total knee arthroplasty (TKA) in enhancing early rehabilitation lacks consensus. The aim of this systematic review and meta‐analysis was to investigate (1) whether cryotherapy is able to promote the rehabilitation of patients undergoing TKA and (2) whether continuous cold flow device has superior results than cold pack in cryotherapy.A comprehensive trial searching was performed in the PubMed, Embase, Cochrane Library, and Google Scholar electronic databases in May, 2024. Randomized controlled trials (RCTs) comparing cryotherapy with no cryotherapy or comparing continuous cold flow device with cold pack after TKA were included. The primary outcome was visual analogue scale (VAS) of pain, and secondary outcomes included opioid consumption, blood loss (hemoglobin decrease and drainage), range of motion (ROM), swelling, length of stay (LOS), and adverse event.A total of 31 RCTs were included in this meta‐analysis with 18 trials comparing cryotherapy with no cryotherapy and 13 trials comparing continuous cold flow device with cold pack. Pooled results showed cryotherapy group had significantly lower VAS scores than no cryotherapy group on postoperative day (POD) 1 (MD, −0.59 [95% CI, −1.14 to −0.04]; p = 0.04), POD 2 (MD, −0.84 [95% CI, −1.65 to −0.03]; p = 0.04), and POD 3 (MD, −0.86 [95% CI, −1.65 to −0.07]; p = 0.03). Cryotherapy group also showed reduced opioid consumption, reduced hemoglobin loss, decreased drainage, and improved ROM after TKA. Continuous cold flow device group had comparable VAS, opioid consumption, blood loss, ROM, knee swelling, and LOS with cold pack group.Cryotherapy can effectively alleviate postoperative pain, reduce blood loss, improve ROM, and thus promote the postoperative rehabilitation for TKA patients, but the continuous cold flow device did not show better efficacy than cold packs. These findings support the routine use of cryotherapy for the rapid rehabilitation of TKA patients, and the traditional cold pack is still recommended. [ABSTRACT FROM AUTHOR]

Background: Vital pulp therapy (VPT) is recommended as an alternative treatment to root canal therapy (RCT) for management of teeth with carious pulp exposure. This randomized clinical trial aimed to compare the outcomes and postoperative pain, and to evaluate the time and cost after full pulpotomy (FP) and RCT in mature molar teeth with irreversible pulpitis (IP). Methods: A total of 160 mature molar teeth with IP were randomly divided into two treatment groups. The FP group (test group) was treated with FP using iRoot BP Plus by an endodontist, the RCT group (control group) was treated with RCT using iRoot SP as sealer by the same endodontist. Pain was recorded preoperatively and daily until day 7 postoperatively. The treatment time and cost were recorded. Clinical and radiographic assessments were collected, and pulp sensibility tests were done by electric pulp test (EPT) at 3-, 6-, 12- month postoperatively. Data were analyzed through chi-square test, Mann-Whitney U test, Fisher exact and independent t test. Results: FP and RCT had comparable success rates (Clinical, 97.3% vs. 98.6%; radiographic, 93.3% vs. 94.6%) (P > 0.05). Pain levels decreased over time from day 1 to day 7 postoperative in both groups, and the FP group had larger reductions in pain intensity than RCT at day 1 (P < 0.05). In the FP group, there were 5, 3 and 3 unresponsive teeth with EPT at 3-, 6- and 12- month follow-ups, respectively. The treatment time and cost in the FP group were significantly lower than in the RCT group (P < 0.05). Conclusions: FP could be an appropriate alternative treatment for management of mature teeth with IP in short follow-up. Trial registration: The trial was registered in Chinese Clinical Trial Registry (ChiCTR2200063380 at 05/09/2022). [ABSTRACT FROM AUTHOR]

Objective To investigate the safety and clinical effect of prophylactic ileostomy using right lower abdominal specimen extraction incision in laparoscopic rectal low anterior resection and its impact on ileostomy closure. Methods A retrospective analysis was conducted on 127 patients who underwent laparoscopic low anterior resection of rectal cancer combined with prophylactic ileostomy in Department of General Surgery in our hospital from January 2020 to December 2023. Patients were divided into observation group (n = 60) and control group (n = 67) based on whether with prophylactic ileostomy using the right lower abdominal specimen extraction incision or not. Relevant data and clinical data of ileostomy closure were compared between the two groups. Results (1) There was no significant difference in baseline clinical data between the two groups (P > 0.05). (2) In terms of operation time, pain score within three days after surgery and postoperative first exhaust time, the observation group was better than the control group, showing statistical difference ( P < 0.05 ). In the observation group, the average length of the incision was longer than that in the control group, and it was significantly different between the two groups (P < 0.05). There was no significant difference between the two groups in terms of blood loss, postoperative feeding time and postoperative hospital stay (P > 0.05). (3) There was no significant difference between the two groups in postoperative and ostomy-related complication S (P > 0.05). (4) The observation group was better than the control group in terms of postoperative pain score and postoperative first exhaust time, indicating statistical significance (P < 0.05). There were no significant differences in surgical time, abdominal adhesion, blood loss, postoperative hospital stay and postoperative complications between the two groups (P > 0.05). Conclusion The patients undergoing laparoscopic rectal low anterior resection who needs prophylactic ileostomy using right lower abdominal specimen extraction incision can improve the appearance of the incision, shorten operation time, reduce postoperative pain of the patients but does not increase postoperative complications and the difficulty of ileostomy closure. It is safe and feasible, which worthy for clinical promotion. [ABSTRACT FROM AUTHOR]

Objective: Given the lack of global consensus on anesthesia selection for peritoneal dialysis catheter (PDC) placement via open surgery, this study investigates the safety and efficacy of combining local infiltration anesthesia (LIA) with monitored anesthesia care (MAC) in patients with end-stage renal disease (ESRD). Methods: This retrospective analysis of ESRD patients who underwent open surgical placement of PDC in the Department of Nephrology, the First Affiliated Hospital of the Army Medical University from 1 August 2020 to 31 May 2022. Patients were categorized into two groups based on anesthesia method: LIA group and LIA + MA group. MA was defined as preoperative sedation (0.2–0.7 µg/kg/h) with dexmedetomidine injection (Huidrican trade name, DEX), and intraoperative analgesia with dexrazoxane injection (Garonin trade name, DEZ) as appropriate according to the patients' pain scores. We compared the general clinical data of the two groups of patients, the changes in blood pressure and heart rate during the whole operation, the intraoperative and postoperative pain, the total duration of the operation and the immediate postoperative complications. Results: The study included 123 patients (59 in the LIA + MAC group and 64 in the LIA group). The LIA + MA group exhibited lower pain scores measured by Visual Analogue Scale(VAS) during surgery (skin incision, subcutaneous adipose tissue dissection, anterior fascia, muscle traction, posterior fascia, peritoneum, and catheterization) compared to the LIA group(p<0.05). In terms of surgical incisions, to intraoperative pain scores (VRS), the LIA + MA group showed higher score level I and lower score level II compared to the LIA group (p = 0.002, 0.004, respectively). The LIA + MA group experienced lower postoperative resting pain (NRS) and VAS than the LIA group (p = 0.001,0.003, respectively). The surgical duration for the LIA + MA group was shorter than that of the LIA group (p<0.001). Preoperative systolic and diastolic blood pressures (SBP and DBP) were higher in the LIA + MA group compared to the LIA group (p<0.001,<0.001, respectively). Postoperative heart rate and DBP were lower in the LIA + MA group (p<0.001, 0.004, respectively). The LIA + MA group exhibited greater changes in heart rate, SBP, and DBP during and after surgery compared to the LIA group (p = 0.009, <0.001,<0.001, respectively). In terms of immediate postoperative complications, the proportion of patients requiring analgesics within 24 h post-surgery was significantly lower in the LIA + MA group (p = 0.031). Conclusion: Open surgery for PDC placement under LIA + MAC is both safe and effective. The key points: There is no global consensus on the preferred anesthesia method for PDC placement. DEX combined with analgesics may yield synergistic effects and serve as a backup rescue analgesic. PDC placement under LIA + MA is safety and efficacy. [ABSTRACT FROM AUTHOR]

Aim Method Results Conclusion Patients undergoing surgery experience perioperative anxiety and pain. Music has been shown to reduce perioperative anxiety, pain and medication requirement. This study assessed the feasibility and effectiveness of implementing a perioperative music intervention.A prospective pre‐ and post‐implementation pilot study was conducted to assess adherence to the intervention and the initial effect of music on postoperative pain scores (Numerical Rating Scale, 0–10) compared to a control group. Secondary outcomes encompassed pain scores throughout hospital admission, anxiety levels, medication usage, complications and hospital stay length.Adherence to the music intervention was preoperative 95.2%, intraoperative 95.7%, postoperative 31.9% and overall 29.7%. The intervention did influence postoperative pain. Patient's willingness to receive music was high (73%), they appreciated the intervention (median 8.0, interquartile range 7.0–9.0) and healthcare professionals were willing to apply the intervention. Music significantly reduced postoperative anxiety (2.0 vs. 3.0, p = 0.02) and the consumption of benzodiazepines on the first postoperative day (number of patients: zero [0%] vs. five [10%], p = 0.04).Implementation of music resulted in reduced postoperative anxiety and decreased consumption of benzodiazepines, and the strategy was feasible, but adjustments are needed to improve postoperative adherence. Both patients and healthcare professionals had a positive attitude towards the intervention. [ABSTRACT FROM AUTHOR]

The article discusses the use of erector spinae block (ESP) for postoperative pain management in low-resource settings. It compares ESP block with rectus sheath block in patients undergoing midline abdominal surgery and finds that ESP block reduces analgesic consumption. However, the article highlights the lack of robust research and publication bias surrounding fascial plane blocks, and cautions against interpreting study results too definitively. The authors stress the importance of patient-centered outcomes and call for further research to determine the optimal approach. They also discuss the limitations and uncertainties of ESP block. The article acknowledges a study by Urmale et al. that supports the effectiveness of ESP block, but emphasizes the need for more comprehensive trials with patient-centered outcomes. The authors advocate for considering cultural, socioeconomic, psychological, and individual patient differences in pain research, and suggest that multicenter studies should be the standard practice. They express gratitude to Urmale et al. for contributing to the discussion and promoting better peri-operative care. [Extracted from the article]

Background: Oral dose formulations must be soluble in gastrointestinal fluids for systemic absorption. The solubility of meloxicam was determined in 16 different age-specific simulated gastric and intestinal media that mirrored the microenvironments in pediatrics and adults. Methods: The solubility of meloxicam in the 16 different age-specific simulated gastric and intestinal biorelevant media was assessed using the standard US pharmacopeial method. The molecular descriptors of meloxicam were used to assess its intestinal permeability. Results: Meloxicam exhibited low solubility in the age-specific simulated gastric media for fasted and fed states and in pediatrics and adults. Similarly, meloxicam exhibited low solubility in the age-specific simulated media that mirrored neonates fed cow milk-based formula. On the other hand, meloxicam exhibited high solubility in the rest of the age-specific pediatric and adult intestinal media that simulated the fasted and fed states. The pediatric-to-adult solubility ratios were outside the 80–125% range in 7 (58.3%) and was borderline in 1 (8.3%) out of the 12 calculated ratios. These findings indicated that the solubility of meloxicam showed clinically significant differences in 8 (66.7%) of the compared media. Conclusion: Meloxicam exhibited low solubility in the age-specific simulated gastric media and high solubility in the simulated intestinal media for adults and pediatrics. Moreover, the pediatric-to-adult solubility ratios may have clinically significant implications. These differences can be translated into a higher likelihood of failing to demonstrate bioequivalence of different formulations containing meloxicam and variabilities in the performance of these formulations.
