Introduction: Pain after lower limb orthopaedic surgeries may be severe, thus adequate pain control can be a challenge. Lower limb orthopaedic surgeries include commonly; knee fractures, total and uni-compartmental knee replacement, knee arthroscopy, anterior cruciate ligament reconstruction, tibial fractures, the age of presentation usually of geriatric group for the former. Femoral nerve block (FNB) is many times provide successful analgesia in above described patients. However, in the absence of epidural or FNB, alternative method as adductor canal block (saphenous nerve block, which is the largest sensory branch of femoral nerve) can be an alternative method, which is not popularly described. This is because inadequate knowledge and understanding of sensory nerve supply of saphenous nerve to the knee and tibia. Aim: to compare the efficacy of analgesic method of Adductor Canal Block (ACB) using local anaesthetic to that of Intravenous Tramadol (IVT) for postoperative analgesia, in patients undergoing orthopaedic lower limb surgeries. Method: Eligible patients aged between 18-80 years, ASA grade I-II, posted for elective surgeries between October 2016 and June 2018. Patients aged between 18-80 years who underwent surgeries for lower limb including knee fractures, tibial fractures etc. were divided into two groups (Group 1 and Group 2). Results: The mean age for Group 1 was 40.6 ± 15.8 and Group 2 was 36.6 ± 14.1. In group 1 there were 20 males (76.9 %) and 6 females (23.1%). Conclusion: We have demonstrated the superior quality of analgesia with single shot injection adductor canal block in patients undergoing lower limb surgeries. [ABSTRACT FROM AUTHOR]

Surgical procedures and post‐traumatic management of dental patients require effective pain management during treatment, but being considerably more invasive than conservative treatments, pain management is required into the postoperative period. Clinical trials on pain intensity following dental surgical procedures (e.g., 3rd molar extraction, implant placement, periodontal, and endodontic surgery) have shown that pain is most intense approximately 5–6 h after completion of the procedure, reaching its peak levels during the first postoperative day. Greatest consumption of analgesics occurs during the first 48–72 h after 3rd molar extraction. For the management of perioperative pain associated with either conservative or surgical dental treatment, the local anesthetics articaine, lidocaine, mepivacaine, and prilocaine are preferred. These drugs, with a vasoconstrictor, provide a rapid onset and a duration of pulpal anesthesia adequate to complete most dental and surgical procedures painlessly. For management of post‐traumatic and postsurgical pain, bupivacaine—administered by an appropriate nerve block—near the conclusion of a surgical procedure, can provide the patient with a pain‐free period of up to 12 h. Nonsteroidal anti‐inflammatory drugs represent the most effective drugs for the management of dental postsurgical pain. NSAIDs, as a group in therapeutic doses, have numbers needed to treat (NNTs) ranging from 2 to 3, while opioid analgesics do not approach those for NSAIDs. A protocol for management of pain following surgical procedures and traumatic injuries is discussed in this paper and includes preemptive NSAID; perioperative pain management; postoperative pain management—local anesthesia; postoperative pain management—analgesics; postoperative telephone call.

• Regional blocks promise to be an adequate alternative to traditional epidural anesthesia in open liver surgery patients. • Transversus abdominis plane block (TAPB) seems to decrease time to flatus in open liver surgery patients. • TAPB decreased pain at rest at 24 hours after open liver surgery, but it was not clinically significant. • TAPB does not improve opioid use, side effects, or length of hospital stay in open liver surgery patients. The objective of this meta-analysis is to evaluate the efficacy of Transversus Abdominis Plane Block (TAPB) in pain control and recovery after open hepatic surgery. We searched for the articles in PubMed, Google Scholar, and the Cochrane Library published before March 2022. We included randomized controlled trials (RCTs) comparing TAPB with a placebo in adult patients after open liver surgery. Meta-analysis was conducted in RevMan 5.4. Methodological quality was assessed via the Jadad/Oxford scale and Cochrane Risk of Bias tool. Five RCTs with 347 patients were included. All studies had an acceptable Jadad score or higher. For pain at rest at 24 hours postoperatively, the standardized mean difference (SMD) with a 95% confidence interval (CI) was −1.08 [−1.97, −0.18], P -value 0.02, favoring TAPB. Models for total opioid consumption, nausea and vomiting, and duration of hospital stay did not demonstrate a difference between the groups. The model for time to first flatus favored TAPB with SMD with a 95% CI of −1.48 [−2.72, −0.24], P -value 0.02. Our meta-analysis of five RCTs favored TAPB regarding pain control at rest and time to first flatus. Due to the small sample size and considerable heterogeneity, more RCTs are needed. CRD42022320565.

Background: Thoracic epidural analgesia is commonly used for upper gastrointestinal surgery. Intrathecal morphine is an appealing opioid-sparing non-epidural analgesic option, especially for laparoscopic gastrointestinal surgery. Methods: Following ethics committee approval, we extracted data from the electronic medical records of patients at Royal North Shore Hospital (Sydney, Australia) that had upper gastrointestinal surgery between November 2015 and October 2020. Postoperative morphine consumption and pain scores were modelled with a Bayesian mixed effect model. Results: A total of 427 patients were identified who underwent open (n = 300), laparoscopic (n = 120) or laparoscopic converted to open (n = 7) upper gastrointestinal surgery. The majority of patients undergoing open surgery received a neuraxial technique (thoracic epidural [58%, n = 174]; intrathecal morphine [21%, n = 63]) compared to a minority in laparoscopic approaches (thoracic epidural [3%, n = 4]; intrathecal morphine [12%, n = 14]). Intrathecal morphine was superior over non-neuraxial analgesia in terms of lower median oral morphine equivalent consumption and higher probability of adequate pain control; however, this effect was not sustained beyond postoperative day 2. Thoracic epidural analgesia was superior to both intrathecal and non-neuraxial analgesia options for both primary outcomes, but at the expense of higher rates of postoperative hypotension (60%, n = 113) and substantial technique failure rates (32%). Conclusions: We found that thoracic epidural analgesia was superior to intrathecal morphine, and intrathecal morphine was superior to non-neuraxial analgesia, in terms of reduced postoperative morphine requirements and the probability of adequate pain control in patients who underwent upper gastrointestinal surgery. However, the benefits of thoracic epidural analgesia and intrathecal morphine were not sustained across all time periods regarding control of pain. The study is limited by its retrospective design, heterogenous group of upper gastrointestinal surgeries and confounding by indication. [ABSTRACT FROM AUTHOR]

Background: We questioned whether the triple analgesic pathways procedure via local infiltration analgesia (LIA), peripheral nerve blocks, and intrathecal morphine (ITM) is superior to LIA only for controlling pain after Total Knee Arthroplasty (TKA). Methods: This retrospective study included 192 primary TKA patients. Group A (76 patients) received LIA only, Group B (61 patients) had ITM, adductor canal block and LIA, while Group C (55 patients) received ITM, femoral nerve block and LIA. A propensity score-matched analysis was used to compare visual analog scales (VAS) for pain intensity, total amount of morphine consumption (TMC), angle of knee flexion, and length of hospital stay (LHS). Results: Group A showed significantly higher VAS than Group B at 12 h (4.27 ± 2.70 vs 2.42 ± 2.35) and 18 h (4.24 ± 2.35 vs 2.18 ± 2.02), and significantly higher than Group C at 6 h (3.46 ± 3.07 vs 0.60 ± 1.50), 12 h (4.27 ± 2.70 vs 0.89 ± 1.48), and 18 h postoperative (4.24 ± 2.35 vs 1.82 ± 2.18). However, the VAS of Group C and B converged to equalize with Group A after 12 and 18 h, respectively. The TMC at 48 h postoperative of Group A was higher than that of Group B (p < 0.01). Nevertheless, there was no difference between groups in terms of knee flexion and LHS, except the LHS of Group B was longer than Group A (p = 0.04). Conclusion: Triple analgesic pathways could provide a better initial analgesic profile. However, the pain seems to be rebound after resolution of nerve block and ITM, with potentially longer LHS.

Active participation in pain management is vital to improve postoperative pain outcomes. However, this issue has not been fully examined in Vietnam. This study aimed to examine the active participation of patients in pain management after surgery, as well as explore its effect on acute postoperative pain. A hospital-based survey on 245 patients after surgery was conducted. Information about demographic and clinical characteristics, pain intensity and active participation in pain management was collected. Multivariate regression models were utilized to determine the associations. 53.9% of patients reported that they were informed about the postoperative pain relief method before surgery. One-third (33.5%) of patients selected preferred pain relief methods; 46.1% reported that they asked physicians when feeling pain immediately after surgery; 49.8% asked physicians when pain was not relieved after taking medications, and 52.2% asked physicians for their current pain in the time of interview. Age and occupation were found to be positively associated with active participation score. Patients being informed about the postoperative pain relief method before surgery had 0.87 points higher than those not receiving explanation (Coef. = 0.87; 95%CI = 0.49–1.26). Patients with high active participation scores were more likely to have pain improvement (OR = 3.41, 95%CI = 2.37–4.92). This study highlights a low level of active participation in postoperative pain management among Vietnamese patients. Routinely providing information about pain control before surgery, and encouraging patients to actively participate in pain management are essential to improve postoperative pain outcomes.

Introduction: A short duration, palliative radiotherapy schedule for locally advanced and unresectable head and neck cancer (LAUHNC) was evaluated in terms of palliation of cancer-related symptoms and acute toxicities. Aims and objectives: The aim of the study was to compare the role and feasibility of hypo-fractionated radiotherapy with concurrent chemotherapy and hypo-fractionated radiotherapy in LAUHNC. Materials and methods: All the patients included in this study of LAUHNC were not fit for curative treatment. These patients are assessed on the basis of quality of life (QOL), tumour response, toxicities, and relief in symptoms. QOL was assessed on the basis of University of Washington QOL questionnaire version 4 before and after treatment. Patients are divided into two arms, Arm A patients received 40 Gy in ten fractions concurrent cisplatin 50 mg/m2 with weekly and Arm B patients received 40 Gy in ten fractions. To assess the tumour response response evaluation criteria in solid tumours criteria were used. Results: A total of 40 patients were enrolled in this study, with 20 patents in both arms. Three patients defaulted during treatment and one patient died during treatment. A total of 36 patients completed treatment. Before treatment common complaints was distressing pain in primary site, and difficulty in chewing and swallowing. After treatment there was reduction of pain and improvement in swallowing in both arms. Overall QOL improvement in Arm A (28.89 ± 18.44 to 46.67 ± 15.34) and in Arm B (31.11 ± 15.68 to 43.33 ± 15.72). Neither of the arms experienced grade IV mucositis and skin reaction. Conclusion: Toxicity in the form of mucositis and dermatitis was higher in the concurrent hypo-fractioned arm compared to the only hypo-fractionated radiotherapy arm during the treatment and in follow up period. The QOL in both individual arms showed statistically significant results, however when the QOL of both the arms was compared, the results were not statistically significant. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this scoping review was to determine the effectiveness of the platelet-rich fibrin in the control of pain associated with alveolar osteitis. Materials and methods: Reporting was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews. A literature search was conducted in the PubMed and Scopus databases to identify all clinical studies on the application of platelet-rich fibrin in the control of pain caused by alveolar osteitis. Data were extracted independently by two reviewers and qualitatively described. Results: The initial search returned 81 articles, with 49 identified after duplicates removal; of these, 8 were selected according to the inclusion criteria. Three of the eight studies were randomized controlled clinical trials, and four were non-randomized clinical studies, two of which were controlled. One study was case series. In all of these studies, pain control was evaluated using the visual analog scale. Overall, the use of platelet-rich fibrin resulted effective in the control of pain determined by alveolar osteitis. Conclusions: Within the limits of this scoping review, the application of platelet-rich fibrin in the post-extra-extraction alveolus reduced the pain associated with alveolar osteitis in almost all the included studies. Nevertheless, high-quality randomized trials with adequate sample size are warranted to draw firm conclusions. Clinical relevance: Pain associated with alveolar osteitis causes discomfort to the patient and is challenging to be treated. Use of platelet-rich fibrin could be a promising clinical strategy for pain control in alveolar osteitis if its effectiveness will be confirmed by further high-quality studies.

The aim of this study was to determine the effectiveness of meloxicam with or without dipyrone on the welfare of ewes subjected to non‐surgical embryo recovery (NSER). Two studies were carried out using 51 multiparous Santa Inês ewes. All animals received a standard oestrous synchronization treatment and a superovulatory protocol. In Study 1, 12 ewes received meloxicam (GM) before cervical transposition (1 mg kg−1, i.v.), repeated 24 h after (1 mg kg−1, i.m.), while the other 10 received a saline solution, remaining as a control group (GC1). In Study 2, ewes were allocated into a group of 15 ewes treated as GM of Study 1 associated with dipyrone (GMD; 50 mg kg−1, i.m.) before cervical transposition, 12 h, and 24 h after, or a control group (GC2) of 14 ewes treated with saline solution. In both studies, heart and respiratory rates (RR), cortisol, glucose, total proteins, albumin and globulins blood concentration were recorded before sedation (BS), after sedation (AS), after cervical transposition, immediately after collection (IAC), and 0.5, 1.5, 3, 6, 12, 24 and 48 h after embryo collection (hAC). In Study 1, RR tended to be greater in GC1 (p =.08), serum total proteins and globulins values were lower and serum albumin values were greater in this group than GM (p =.003, p <.0001, and p <.0001, respectively). In Study 2, treatment of GMD tended to reduce the glycaemia at AS (p =.052) and reduced it at 3hAC (p <.0001), and 6hAC (p =.03). It also tended to reduce cortisol concentrations (p =.10). The other variables varied with NSER without interaction with the experimental treatments. In conclusion, in this study condition, NSER in sheep induced transient changes indicative of stress and possibly pain, therefore, affecting animal welfare. The administration of meloxicam was ineffective to reduce those responses, and the association of dipyrone had only slight effects without modifying the main welfare indicative responses in ewes subjected to NSER.

Perioperative pain control is an important component of any plastic surgery practice. Due to the incorporation of Enhanced Recovery after Surgery (ERAS) protocols, reported pain level, opioid consumption, and hospital length of stay numbers have decreased significantly. This article provides an up-to-date review of current ERAS protocols in use, reviews individual aspects of ERAS protocols, and discusses future directions for the continual improvement of ERAS protocols and control of postoperative pain. ERAS protocols have proven to be excellent methods of decreasing patient pain, opioid consumption, and postanesthesia care unit (PACU) and/or inpatient length of stay. ERAS protocols have three phases: preoperative education and pre-habilitation, intraoperative anesthetic blocks, and a postoperative multimodal analgesia regimen. Intraoperative blocks consist of local anesthetic field blocks and a variety of regional blocks, with lidocaine or lidocaine cocktails. Various studies throughout the surgical literature have demonstrated the efficacy of these aspects and their relevance to the overall goal of decreasing patient pain, both in plastic surgery and other surgical fields. In addition to the individual ERAS phases, ERAS protocols have shown promise in both the inpatient and outpatient sectors of plastic surgery of the breast. ERAS protocols have repeatedly been shown to provide improved patient pain control, decreased hospital or PACU length of stay, decreased opioid use, and cost savings. Although protocols have most commonly been utilized in inpatient plastic surgery procedures of the breast, emerging evidence points towards similar efficacy when used in outpatient procedures. Furthermore, this review demonstrates the efficacy of local anesthetic blocks in controlling patient pain. [ABSTRACT FROM AUTHOR]

Interscalene nerve blocks and local anesthetic infiltration are 2 methods commonly used in multimodal analgesia regimens for shoulder arthroplasty. Liposomal bupivacaine is a novel anesthetic that can be detected more than 24 hours following local administration. Studies comparing liposomal bupivacaine with conventional analgesic methods have found mixed results regarding pain and narcotic consumption, and there is little information available regarding patient satisfaction and the role of psychosocial variables. This is a randomized study of 76 adult patients undergoing reverse shoulder arthroplasty who were assigned to receive a preoperative interscalene nerve block with ropivacaine (Block = 38) or an intraoperative periarticular injection of liposomal bupivacaine (Local = 38). The primary outcomes were narcotic consumption (MEq, morphine equivalents), visual analog scale (VAS) pain scores, and satisfaction (0-10). The secondary outcomes were the effect of patient group preference (Block vs. Local) and psychosocial variables (Pain Catastrophizing Scale, Brief Resilience Scale) on satisfaction. Length of stay, pain-related phone calls, pain-related readmissions, and the number of narcotic refills were tracked from the day of surgery through the first postoperative appointment, which was routinely 7-14 days following surgery. Intraoperative and day 0 narcotic consumption was lower in the Block group by 17.3 and 21.6 MEq (P <.001, P =.035) with no differences on day 1 or 2. There was no difference in VAS pain scores, length of stay, pain-related phone calls, pain-related readmissions, or the number of narcotic refills. Patient satisfaction was higher in the Block group (8.3 vs. 6.8, P =.017). Pain catastrophizing, resilience, and patient group preference did not have any significant relationship with patient satisfaction. Patients undergoing reverse shoulder arthroplasty have higher satisfaction with a conventional interscalene block compared to a periarticular injection of liposomal bupivacaine. There were no clinically important differences in narcotic consumption, VAS pain scores, length of stay, pain-related phone calls, pain-related readmissions, or the number of narcotic refills. The Pain Catastrophizing Scale, Brief Resilience Scale, and patient preferences did not have any relationship with patient satisfaction. [ABSTRACT FROM AUTHOR]

Background: Children's pain in dentistry has undesirable short‐ and long‐term consequences; therefore, less invasive treatments merit consideration. Aim: To investigate procedural pain scores for two treatments for carious primary molars in New Zealand primary care. Design: This study was a split‐mouth randomised control trial, with secondary outcome analysis. Children (4–8 years) with proximal carious lesions on matched primary molars had one tooth treated with the Hall technique (HT) and one treated with a conventional stainless steel crown (CT); treatment type and order of treatment were randomly allocated (allocation concealment). The Wong–Baker self‐report pain scale measured pretreatment dental pain, procedural pain at each treatment and post‐operative pain. Results: Data were analysed for 103 children: 49 children had the HT first and 54 children had the CT first. Procedural pain scores did not differ by treatment type, with 71.8% and 76.7% of children reporting low pain for the HT and the CT, respectively. Fewer children reported low procedural pain for the second treatment than the first (p =.047). Most children reported low procedural pain for both treatments (58.3%), although 41.7% experienced moderate–high procedural pain with at least one treatment. Conclusions: The HT caused pain for as many children as the CT. There is an opportunity for better dental pain management in this setting. [ABSTRACT FROM AUTHOR]

Background: It is advised to use a regional block to lower postoperative opioid usage. Therefore, we aimed to compare the analgesic effect of erector spinae plane block (ESPB) and thoracic paravertebral block (TPVB) on the need for morphine following video-assisted thoracic surgery (VATS). Results: The findings revealed that TPVB and ESPB groups were equivalent in analgesic efficacy with postoperative morphine consumption in mg 15.2 ± 2.7 and 14.9 ± 2.4 respectively. statistically significant shorter block time in ESPB was 8.1 ± 1.7 min in contrast to 11.35 ± 1.7 min in TPVB and better patient satisfaction in the ESPB than in TPVB groups (p value < 0.05). No statistically significant differences existed between the two groups in terms of postoperative pain score (VAS) at rest, cough at any time point, or incidence of complications (p value > 0.05). There were significantly lower heart rate (HR) and blood pressure (BP) trends in 15 and 30 min intraoperatively (p value < 0.001) in the TPVB group. Conclusions: ESPB has analgesic efficacy equivalent to TPVB from aspects of equivalent postoperative morphine consumption and VAS at rest and during cough with shorter block time and better patient satisfaction.

Background: Many patients suffered from serious pain after breast augmentation, but the analgesic efficacy of pectoral nerve block for these patients was not well established. Thus, this meta-analysis was intended to study the analgesic efficacy of pectoral nerve block for breast augmentation. Methods: Several databases including PubMed, EMbase, Web of Science, EBSCO, and Cochrane library databases were searched, and we included randomized controlled trials (RCTs) regarding the analgesic efficacy of pectoral nerve block for breast augmentation. Results: Six RCTs were ultimately included in this meta-analysis. Compared with control intervention for breast augmentation, pectoral nerve block could significantly reduce pain scores at 1 h (mean difference [MD] = -2.28; 95% confidence interval [CI] = -3.71 to -0.85; P = 0.002), 2 h (MD = -3.08; 95% CI = -3.95 to -2.20; P < 0.00001), 4 h (MD = -2.95; 95% CI = -3.32 to -2.58; P < 0.00001), 6-8 h (MD = -2.68; 95% CI = -3.24 to -2.11; P < 0.00001), 24 h (MD = -2.04; 95% CI = -2.41 to -1.67; P < 0.00001), the number of analgesic requirement (odd ratio [OR] = 0.20; 95% CI = 0.09 to 0.45; P = 0.0001), and the incidence of nausea (OR = 0.21; 95% CI = 0.08 to 0.54; P = 0.001) and vomiting (OR = 0.15; 95% CI = 0.05 to 0.39; P = 0.0001). Conclusions: Pectoral nerve block may be effective for pain relief after breast augmentation. [ABSTRACT FROM AUTHOR]

To mitigate the opioid crisis, physicians are reevaluating opioid prescribing patterns. To evaluate outcomes of maximal opioid reduction on top of an existing Enhanced Recovery after Surgery (ERAS) pathway in our The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited bariatric surgery program. Academic tertiary care hospital, United States. Patients undergoing primary bariatric operation were studied from July 2017 to April 2019, (standard ERAS cohort), and compared to patients from April 2019 to February 2021 (standard ERAS with Sparing Opioid Use Postoperatively protocol) (SOUP cohort). The primary endpoint was reduction of perioperative opioid use. Of 367 patients, 212 (57.8%) and 155 (42.2%) were in the ERAS and SOUP cohorts, respectively. Roux-en-Y gastric bypass was 48.6% (n = 103) versus 54.2% (n = 84) and sleeve gastrectomy was 51.4% (n = 109) versus 45.8% (n = 71) for ERAS versus SOUP, respectively (P =.29). The SOUP cohort of patients required a low median inpatient morphine equivalent dose of 4 mg [0–6.2]. The ERAS cohort was discharged on a higher morphine equivalent dose than the SOUP cohort at 186.7 mg ± 92.9 versus 37.6 ± 32.3 (P <.05), and median consumption of the standard 5 mg oxycodone tablet was 1.5 tablets [0–4]. The SOUP cohort patients rated their pain satisfaction score on a scale of 1 to 10 at 9.1 points (standard deviation ± 1.8). The SOUP cohort had a shorter length of stay (P <.05), with comparable readmission rates. An opioid-sparing protocol can be implemented after bariatric surgery with high overall satisfaction with pain control. • Opioids can be reduced drastically after primary bariatric surgery. • Patients remain with high pain satisfaction despite decreased narcotics. • Readmission rates are unchanged with decreased narcotic usage.

Objective: To assess the clinical implications of cryoanalgesia for pain management in children undergoing minimally invasive repair of pectus excavatum (MIRPE). Background: MIRPE entails significant pain management challenges, often requiring high postoperative opioid use. Cryoanalgesia, which blocks pain signals by temporarily ablating intercostal nerves, has been recently utilized as an analgesic adjunct. We hypothesized that the use of cryoanalgesia during MIRPE would decrease postoperative opioid use and length of stay (LOS). Materials and Methods: A multicenter retrospective cohort study of 20 US children's hospitals was conducted of children (age below 18 years) undergoing MIRPE from January 1, 2014, to August 1, 2019. Differences in total postoperative, inpatient, oral morphine equivalents per kilogram, and 30-day LOS between patients who received cryoanalgesia versus those who did not were assessed using bivariate and multivariable analysis. P value <0.05 is considered significant. Results: Of 898 patients, 136 (15%) received cryoanalgesia. Groups were similar by age, sex, body mass index, comorbidities, and Haller index. Receipt of cryoanalgesia was associated with lower oral morphine equivalents per kilogram (risk ratio=0.43, 95% confidence interval: 0.33–0.57) and a shorter LOS (risk ratio=0.66, 95% confidence interval: 0.50–0.87). Complications were similar between groups (29.8% vs 22.1, P =0.07), including a similar rate of emergency department visit, readmission, and/or reoperation. Conclusions: Use of cryoanalgesia during MIRPE appears to be effective in lowering postoperative opioid requirements and LOS without increasing complication rates. With the exception of preoperative gabapentin, other adjuncts appear to increase and/or be ineffective at reducing opioid utilization. Cryoanalgesia should be considered for patients undergoing this surgery. [ABSTRACT FROM AUTHOR]

Despite established opioid-free protocols for postoperative analgesia after common orthopaedic sports procedures, many patients continue to request opioids postoperatively. The purpose of this study was to elucidate patient factors influencing preferences for opioid versus nonopioid postoperative analgesia. Patients (age >/ = 15) without a history of a documented chronic pain disorder who were scheduled for one of ten sports procedure types from August 2020 to May 2021 were eligible for inclusion. Patients were excluded if undergoing revision surgery, had concomitant injuries, had opioids use >3 months preoperatively, or unable to read English. Recruitment ended after 100 patients enrolled. At the patients' preoperative visit, patients were administered a written survey assessing pain medication preferences. Participants completed the Opioid Risk Tool survey, as well as Visual Analog Scale and Patient-Reported Outcome Measurement Information System surveys. One hundred patients participated in the study. Forty-two patients preferred opioids versus 58 patients preferring nonopioid postoperative analgesia. Patients preferring opiates were more likely to have had previous surgery (90.2% vs. 69.6%, p = 0.023) with post-operative pain managed with opiates (87.5% vs 55.4%, p = 0.003), higher preoperative Visual Analog Scale score (6±3.5 vs. 3±2, p < 0.001), reported post-operative pain as a reason for opioids preference (88.1% vs 20.0%, p < 0.001), and were less concerned about addiction (4.8% vs. 45.5%, p < 0.001) and side effects (11.9% vs. 52.7%, p < 0.001). For every unit increase in Visual Analog Scale score, the odds of preferring opioid pain control increased 1.41 times. Patients with a history of prior surgery utilizing opioid pain control, higher Visual Analog Scale scores preoperatively, and concern for inadequately managed postoperative pain were more likely to prefer opioid pain control following common orthopaedic sports procedures. Patients may benefit from increased preoperative education about opioid risks and the role of multimodal pain management regimens. [ABSTRACT FROM AUTHOR]

Dorsal root ganglion (DRG) neurons process pain signaling through specialized nociceptors located in their peripheral endings. It has long been established low voltage-activated (LVA) CaV3.2 calcium channels control neuronal excitability during sensory perception in these neurons. Silencing CaV3.2 activity with antisense RNA or genetic ablation results in anti-nociceptive, anti-hyperalgesic and anti-allodynic effects. CaV3.2 channels are regulated by many proteins (Weiss and Zamponi, 2017), including KLHL1, a neuronal actin-binding protein that stabilizes channel activity by recycling it back to the plasma membrane through the recycling endosome. We explored whether manipulation of KLHL1 levels and thereby function as a CaV3.2 modifier can modulate DRG excitability and mechanical pain transmission or sensitivity to pain. We first assessed the mechanical sensitivity threshold and DRG properties in the KLHL1 KO mouse model. KO DRG neurons exhibited smaller T-type current density compared to WT without significant changes in voltage dependence, as expected in the absence of its modulator. Western blot analysis confirmed CaV3.2 but not CaV3.1, CaV3.3, CaV2.1, or CaV2.2 protein levels were significantly decreased; and reduced neuron excitability and decreased pain sensitivity were also found in the KLHL1 KO model. Analogously, transient down-regulation of KLHL1 levels in WT mice with viral delivery of anti-KLHL1 shRNA also resulted in decreased pain sensitivity. These two experimental approaches confirm KLHL1 as a physiological modulator of excitability and pain sensitivity, providing a novel target to control peripheral pain.

Background and Aim: Treatment of acute postoperative pain is one of the most important measures to improve recovery. Different methods of local and regional anesthesia, and also numerous intravenous drugs have been used. In this study, the analgesic effect ketorolac, paracetamol and pethidine in the postoperative pain control of outpatient transurethral lithotripsy was evaluated. Materials and Methods: This clinical trial was performed on 96 patients who were candidates for outpatient transurethral lithotripsy in Mashhad Imam Reza Hospital. In randomized double blinded study, at the end of the operation, 30 mg of intravenous ketorolac to the first group, 1 gram paracetamol in half an hour to the second group and 50 mg of pethidine to the third group were injected. Pain was assessed every 10 minutes to half an hour and then, every half an hour to 4 hours by numerical rating scale (NRS). Finally, the data were analyzed by SPSS v16 software. The relationship between quantitative variables was analyzed by analysis of variance and the qualitative variables was assessed by Chi-square test and P

Background Subcutaneous lidocaine injection and topical EMLA cream are both used to control lumbar puncture (LP) pain; however, local analgesia usage is not standardized. Methods We conducted a prospective, single-blinded, randomized-controlled crossover trial comparing the two modalities in reducing LP pain. Pediatric patients requiring serial LPs were randomly assigned to receive EMLA cream or lidocaine injection prior to LP. On the subsequent LP, analgesia was defaulted to the other agent. Pain was assessed using the Wong-Baker FACES Pain Rating Scale pre-procedure: 30 to 60 minutes post-LP, and 24 hours post-procedure. Results Ten patients were included in the analysis (median age: 5.5 years). Pain ratings at 1 and 24 hours post-LP did not differ between the two strategies (p = 0.79). No adverse local reactions were reported for either agent. Conclusion Accordingly, both lidocaine and EMLA cream provided effective LP pain control.

Abstract Background Effective symptom control is a stated goal of palliative care (PC) to improve quality of life for terminally ill patients. Virtual reality (VR) provides temporary escapes from pharmacologically resistant pain and allows for experiences and journeys patients may not access in any other way. Enabling wishes through virtual worlds may also offer additional benefits such as controlling psychological and physical symptoms. Aims We investigated the feasibility of a single VR experience as a viable, satisfying, and effective tool for end-of-life pain relief for inpatients presenting palliative needs. Design This is an observational, single-arm and national single-center feasibility trial. Methods A one-time VR experience with a selection of several videos and games was offered to 45 inpatients receiving PC at Muenster University Hospital. Patients with brain tumors, brain metastases, seizures, motion sickness, claustrophobia, vertigo, hearing or visual impairment, or unable to consent were excluded. Primary outcome measured patient reported pain on a visual analogue scale (VAS). We also measured Karnofsky performance status, health-related quality of life (HRQOL) using the EQ-5D-5 L questionnaire, and the Pain Out Questionnaire for postoperative pain. Results We analyzed data from 21 women (52.5%) and 19 men (47.5%) at an average age of 51.9 (SD: 15.81) years. The mean Karnofsky score among the sample was 45.5 (SD: 14.97) and the HRQOL was 41.9 (SD: 23.08). While no serious side effects were reported during the intervention, three patients experienced nausea (7%), two headaches (5%), and three reported dry eyes (7%) afterwards. Significant pain reduction (baseline VAS 2.25 (SD: 0.4399)) was demonstrated during (VAS 0.7 (SD: 0.2983, p

Abstract Background Craniosynostosis is a condition characterized by a premature fusion of one or more cranial sutures. The surgical repair of craniosynostosis causes significant pain for the child. A key focus of craniosynostosis repair is developing effective strategies to manage perioperative pain. This study aimed to review perioperative pain control strategies for craniosynostosis repair systematically. Methods Guidelines for reporting systematic reviews and meta-analyses were used in the design of this review. In May 2022, the following databases were used to conduct the literature search: MEDLINE, Cochrane, EMBASE, and Google Scholar. A search was performed using MeSH terms “craniosynostosis,” “pain management,” and “cranioplasty.” Results The literature review yielded 718 publications. After applying our inclusion criteria, 17 articles were included, accounting for a total of 893 patients. During the postoperative period, most studies used multimodal analgesia, primarily opioids, and acetaminophen. In the postoperative period, oral ibuprofen was the most commonly used NSAID, rectal codeine, and acetaminophen were the most commonly used weak opioids, and continuous remifentanil infusion was the most commonly used potent opioid. Conclusion The authors determined the best pain management options for pediatric patients undergoing cranioplasty by analyzing the most commonly used analgesics. A high-quality clinical trial comparing different types of analgesic combinations would be a valuable addition to the present literature.

Why you should read this article: • To enhance your understanding of the risks of opioid use for managing non-malignant chronic pain • To read about a US-based pilot project that aimed to support patients to manage their pain and reduce their use of opioids • To appreciate the benefits of multidisciplinary education programmes to support patients to reduce their opioid use when managing non-malignant chronic pain As the US is experiencing an opioid epidemic, patients with non-malignant chronic pain must understand the risks of opioids and identify safe and effective treatment alternatives. Multidisciplinary pain management programmes have been shown to be effective in reducing non-malignant chronic pain. A pilot project was conducted in a primary care clinic in the US with the aim of educating patients on the neurophysiology of pain, biopsychosocial responses to pain, risks and benefits of opioids and non-opioid alternatives, and pain management techniques. The programme was shown to be associated with use of reduced amounts of opioids, reduced catastrophising and reduced pain among the 13 participants. After the programme, participants reported having a better understanding of pain and pain management and being willing to work with primary care clinicians to decrease their use of opioids. Programmes that teach patients how to manage chronic pain and reduce opioid use are crucial to addressing the opioid epidemic in the US. [ABSTRACT FROM AUTHOR]

Purpose: We describe the prevalence of the Edmonton Classification System for Cancer Pain (ECS-CP) features in patients with bone metastasis and cancer-induced bone pain (CIBP) and the relationship between ECS-CP features, pain intensity, and opioid consumption. Methods: We assessed ECS-CP features and recoded pain mechanisms and opioid use in adult patients with bone metastasis. Validated measures were used to assess pain intensity, incident pain, psychological distress, addictive behavior, and cognition. Results: Among 147 eligible patients, 95.2% completed the assessment. Mean participant age was 73.2 years, the majority female (52.1%) with breast cancer occurring most commonly (25.7%). One or more ECS-CP features were present in 96.4% and CIBP in 75.7% of patients. The median average and worst pain scores were 3 and 6, respectively. Neuropathic pain was the most prevalent pain mechanism (45.0%) and was associated with breakthrough pain frequency (p=0.014). Three-quarters had incident pain, which was strongly associated with a higher average and worst pain scores (3.5 and 7, p<0.001 for both), background oral morphine equivalent daily dose (26.7mg, p=0.005), and frequency of daily breakthrough analgesia (1.7 doses/day, p=0.007). Psychological distress (n=90, 64.3%) was associated with a significantly higher average pain score (4, p=0.009) and a slightly higher worst pain score (7, p=0.054). Addictive behaviour and cognitive dysfunction were relatively uncommon (18.6% and 12.9%, respectively). Conclusion: There is a need to promote standardized assessment and classification of pain syndromes such as CIBP. The ECS-CP may allow us to consider CIBP in a systematic manner and develop personalized pain interventions appropriate to the pain profile.

Introduction: Despite the newer innovation and recent technological advances in modern dentistry, fear and anxiety constitute an important theme in dentistry. They are a usual reaction to stressful conditions that help children while staying alert in situations of an impending threat. Aim: To evaluate the effect of deep breathing exercise in reducing dental anxiety, behaviour and pain using smartwatch during maxillary buccal infiltration in children aged 7-11 years. Materials and Methods: A prospective interventional and single-blinded randomised clinical trial conducted in the Department of Paediatric and Preventive Dentistry, NDCH, Nellore, Andhra pradesh, India, from November 2019 to October 2020. A total of 70 children of age between 7-11 years. They were randomly allocated into two groups, 35 in each. Children in group I were trained for deep breathing exercise using smartwatch and group II (control group) was traditional tell show do technique. The reaction of children during maxillary buccal infiltration anaesthesia was recorded in terms of behaviour (Frankl's behaviour rating scale), anxiety {Facial Image Scale (FIS) and pulse rate}, and pain perception (Wong-Baker FACES pain rating scale and face, leg, activity, cry and consolability scale). Data was tabulated using Kolmogorov-Smirnov test and Kruskal-Wallis for data distribution. Independent Student's t-test or Mann-Whitney test (Quantitative variables) and Chisquare test or Mann-Whitney test (Qualitative variables) were used to test statistical significance using Statistical Package for Social Sciences (SPSS) version 25.0. Results: The mean age of children in smartwatch group was 8.9±1.4 years and in control group was 8.9±1.6 years with no statistical significant difference. Statistically significant decrease in pulse rate was observed in smartwatch group (p=0.003), subjective anxiety and pain was lowered in intervention group. Objective pain was decreased significantly in smartwatch group (p=0.007). Conclusion: Children performing deep breathing exercise using smartwatch had efficiency to reduce dental anxiety and pain perceived during maxillary buccal infiltration anaesthesia.

Background: Oral mucositis (OM) is one of the most debilitating side effects of chemotherapy. Among the current methods used in OM management, the feasibility of high power laser therapy (HPLT) has been proposed but not fully evaluated. Aim: The aim of this study was to evaluate the efficacy of HPLT in the treatment of OM in paediatric patients. Design: Fourteen oncohematological paediatric patients treated with chemotherapy and/or hematopoietic stem cell transplantation and affected by OM at different grades were enrolled in this study. All patients were treated with a class IV laser device in four sessions for four consecutive days, OM was evaluated with the WHO‐OTS scale. The perception of pain was assessed by the visual analog scale. Photographs of and information about lesions and patient questionnaires were taken and collected, respectively. Descriptive analyses and the Wilcoxon signed‐rank test (nonparametric test) were used, with a statistical significance of α =.05. Results: After a week into the treatment, 57% of patients were completely healed, whereas the whole cohort experienced a drastic decrease in pain, from an average value of 5.8–1.1 (p =.0016). The average number of injuries per patient decreased from 7.4 to 3.1 (p =.008). Conclusion: High power laser therapy appears to be a safe and efficacious method for managing OM. It reduces pain and severity of oral cavity injuries. Further studies are needed to determine the optimal parameters useful in OM treatment and to evaluate the relative effectiveness of HPLT to other treatments like LLLT. [ABSTRACT FROM AUTHOR]

Rib fractures are present in 15% of all traumas and 60% of patients with chest traumas. Rib fractures are not life-threatening in isolation, but they can be quite painful which leads to splinting and compromise of respiratory function. Splinting limits the ability of a patient to take a deep breath, which leads to atelectasis, atelectasis to poor secretion removal, and poor secretion removal leads to pneumonia. Pneumonia is the common pathway to respiratory failure in patients with rib fractures. It is noted that in the elderly, each rib fracture increases developing pneumonia by 27% and the risk of dying by 19%. From a public health perspective, rib fractures have long-term implications with only 59% of patients returning to work at 6 months. In this review we will examine the state of art as it currently exists with regard to the management of pain associated with rib fractures. Included in this overview will be a brief review of the anatomy of the thorax and some important physiologic concepts, the latest trends in pharmacologic and noninvasive means of managing rib pain, a special section on epidural anesthesia, some other alternative invasive methods of pain control, and a review of the recent literature on rib plating. Finally, a practical, easy to follow guideline, to manage the patient with pain from rib fractures will be presented. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to evaluate pain control and patient satisfaction using an opioid-free analgesic regimen following thyroid and parathyroid operations. Methods: Surveys were distributed to all postoperative patients following total thyroidectomy, thyroid lobectomy, and parathyroidectomy between January and April 2020. After surgery, patients were discharged without opioids except in rare cases based on patient needs and surgeon judgment. We measured patient-reported Numeric Rating Scale (NRS) pain scores and satisfaction categorically as either satisfied or dissatisfied. Results: We received 90 of 198 surveys distributed, for a 45.5% response rate. After excluding neck dissections (n = 6) and preoperative opioid use (n = 4), the final cohort included 80 patients after total thyroidectomy (26.3%), thyroid lobectomy (41.3%), and parathyroidectomy (32.5%).The majority reported satisfaction with pain control (87.5%) and the entire surgical experience (95%). A similar proportion of patients reported satisfaction with pain control after total thyroidectomy (90.9%), thyroid lobectomy (90.5%), and parathyroidectomy (80.8%), indicating the procedure did not significantly impact satisfaction with pain control (P =.47). Patients who reported dissatisfaction with pain control were more likely to receive opioid prescriptions (30% vs 2.9%, P <.01), but the majority still reported satisfaction with their entire operative experience (70%). Discussion: Even with an opioid-free postoperative pain regimen, most patients report satisfaction with pain control after thyroid and parathyroid operations, and those who were dissatisfied with their pain control generally reported satisfaction with their overall surgical experience. Therefore, an opioid-free postoperative pain control regimen is well tolerated and unlikely to decrease overall patient satisfaction. [ABSTRACT FROM AUTHOR]

Aim: Buprenorphine is one of the strongest opioids used for the relief of cancer pain. This study aims to evaluate the real‐world clinical experiences of transdermal buprenorphine used in moderate to severe cancer pain in the Asian population. Methods: This is an open‐labeled, multicenter, 4‐week observational study. Stable cancer pain patients who decided to switch the previous opioid to transdermal buprenorphine will be enrolled in this study. The safety and effectiveness were observed and collected. Pain assessment was performed using a numerical rating scale by the investigators and the Brief Pain Inventory Short Form (BPI‐SF) by the patient. The safety profiles included concomitant medications and adverse events (AEs). Results: A total of 83 patients were enrolled in this study. The global pain scores in the BPI, as well as the four individual pain parameters (worst, least, average, and right now), showed a continued decrease (p <.05) from week 2 to week 4. Significant improvements were observed in normal work activities, relations with other people, sleep, enjoyment of life, and global BPI pain interference score on week 4. Pain assessments conducted by investigators demonstrated significant, continuous improvements during the study periods. In addition, transdermal buprenorphine demonstrated good safety/tolerability with limited drug‐related AEs in the Asian population with cancer pain. Conclusion: This study demonstrated that transdermal buprenorphine in the Asian population has good safety profiles and continued improvements in pain relief, sleep, and pain interferences. Transdermal buprenorphine can be an effective and convenient option as a transdermal opioid for patients with moderate to severe cancer pain in Taiwan.

Examine the efficacy and safety of perioperative gabapentin in bariatric surgical patients. Systematic Review and Meta-analysis. An exhaustive search was conducted using PubMed, Cochrane Library, MEDLINE, CINAHL, Google Scholar, and other gray literature. Only randomized controlled trials evaluating the use of gabapentin in bariatric surgery were included. Risk ratio (RR) and mean difference (MD) were used to estimate outcomes with suitable effect models. Quality of evidence was assessed using the Risk of Bias and GRADE system. Four trials consisting of 283 patients were analyzed. The use of gabapentin significantly lowered the cumulative pain score in the first 24 hours after surgery by an average of 1.04 (MD, –1.04; 95% CI, –1.45 to –0.63; P <.00001). Gabapentin also reduced the overall morphine equivalent consumption by 7.89 mg (MD, –7.89; 95% CI, –13.56 to –2.2; P =.006). However, gabapentin did not affect the incidence of PONV (RR, 0.61; 95% CI, 0.38-1.00; P =.05), somnolence (RR, 1.25; 95% CI, 0.57-2.73; P =.57), dizziness (RR, 1.01; 95% CI, 0.40-2.54; P =.99), and headache (RR, 0.76; 95% CI, 0.25-2.30; P =.62). Substantial heterogeneity, imprecision of the effect size, and potential publication bias were limitations of this review. The use of gabapentin is effective in the management of postoperative pain in bariatric surgery. However, there is limited data regarding the opioid-sparing effect and adverse effect profiles of gabapentin in the bariatric surgical population. [ABSTRACT FROM AUTHOR]

Background: Pain management is a critical component of comprehensive postsurgical care, as it influences patient safety and outcomes, and inadequate control has been associated with the development of chronic pain syndromes. Despite recent improvements, the management of postoperative pain following total knee arthroplasty (TKA) remains a challenge. The use of opioid-sparing, multimodal analgesic regimens has broad support, but there is a paucity of high-quality evidence regarding optimal postoperative protocols and novel approaches are needed. Dextromethorphan stands out among both well-studied and emerging pharmacological adjuncts for postoperative pain due its robust safety profile and unique pharmacology. The purpose of this study is to evaluate the efficacy of multi-dose dextromethorphan for postoperative pain control following TKA. Methods: This is a single-center, multi-dose, randomized, double-blinded, placebo-controlled trial. A total of 160 participants will be randomized 1:1 to receive either 60 mg oral dextromethorphan hydrobromide preoperatively, as well as 30 mg 8 h and 16 h postoperatively, or matching placebo. Outcome data will be obtained at baseline, during the first 48 h, and the first two follow-up visits. The primary outcome measure will be total opioid consumption at 24 h postoperatively. Secondary outcomes related to pain, function, and quality of life will be evaluated using standard pain scales, the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) questionnaire, the Patient-Reported Outcomes Measurement Information System (PROMIS-29) questionnaire, and clinical anchors. Discussion: This study has a number of strengths including adequate power, a randomized controlled design, and an evidence-based dosing schedule. As such, it will provide the most robust evidence to date on dextromethorphan utilization for postoperative pain control following TKA. Limitations include not obtaining serum samples for pharmacokinetic analysis and the single-center study design. Trial registration: This trial has been registered on the National Institute of Health's ClinicalTrials.gov (NCT number: NCT05278494). Registered on March 14, 2022. [ABSTRACT FROM AUTHOR]

Background: Continuous local infiltration analgesia (CLIA) can be administered via intraarticular or periarticular techniques in patients undergoing total knee arthroplasty (TKA). The purpose of this investigation was to retrospectively report a single-center experience of epidural analgesia with subcutaneous CLIA versus epidural analgesia without CLIA among patients undergoing TKA. Methods: This single-center retrospective study was conducted in Saudi Arabia. From January 01, 2014, to December 30, 2020, medical records of all patients who underwent TKA were reviewed. Patients who received subcutaneous CLIA with epidural analgesia were assigned to the intervention group, whereas those who received epidural analgesia without subcutaneous CLIA were assigned to the control group. The efficacy endpoints included: (i) postoperative pain scores at 24 h, 48 h, 72 h, and 3 months; (ii) postoperative opioid consumption at 24 h, 48 h, 72 h, and 24–72 h (cumulative); (iii) length of hospital stay; and (iv) postoperative functional recovery of the knee 3 months post-operation, according to the Knee Injury and Osteoarthritis Outcome Score. Results: At rest and during mobilization, the CLIA group (n = 28) achieved significantly lower postoperative pain scores 24 h, 48 h, 72 h, and 3 months post-operation than the non-CLIA group (n = 35). Subgroup analysis revealed that the CLIA group achieved significantly less opioid consumption 24 h and 48 h post-operation than the non-CLIA group. There was no difference between the groups regarding the length of hospital stay or functional scores 3 months post-operation. There was no significant difference between the groups regarding the rate of wound infection, other infections, and readmission within 30 days. Conclusion: Subcutaneous CLIA is a technically feasible and safe procedure without major adverse events but with reduced postoperative pain scores (at rest and during mobilization) and opioid consumption. Additional larger studies are warranted to confirm our results. Moreover, a head-to-head comparison between subcutaneous CLIA and periarticular or intraarticular CLIA is an interesting prospective investigation. [ABSTRACT FROM AUTHOR]

Postoperative pain control is essential to optimizing patient outcomes, improving satisfaction, and allowing patients to resume their baseline functional activities. Methadone, a synthetic mu‐opioid agonist, has multiple pharmacologic properties that may be optimal for perioperative use. Compared to other opioids, methadone has a longer duration of action, rapid onset, extended dosing intervals, high oral bioavailability, low cost, lack of active metabolites, and action on multiple receptors. The current literature examining the use of methadone in the perioperative care of children and adolescents is limited and most often reported within the context of spine or cardiothoracic surgery. Overall, these studies support the hypothesis that perioperative methadone in pediatric patients may decrease postoperative pain, opioid consumption, length‐of‐stay, and the incidence of some opioid‐related side effects, like constipation and urinary retention. A variety of protocols for the perioperative use of methadone have been described, including a single intraoperative dose as well as multiple small doses within multimodal pain protocols. The superiority of these protocols has not been established. Like all opioids, methadone has a side effect profile which includes nausea, vomiting, reduced GI motility, sedation, and respiratory depression at high doses. There is also a concern that it can cause QTc prolongation in patients. The primary aim of this educational review is to examine the pharmacologic data, published perioperative protocols, dosing considerations, and risks and benefits associated with inclusion of methadone in analgesic regimens for surgical patients. A secondary aim is to introduce opportunities for research around the perioperative use of methadone in children and adolescents. Based on our review, we would prioritize establishing optimal procedure‐specific methadone protocols, determining generalizability for use in routine pediatric surgeries, and investigating methadone safety and efficacy prospectively as the primary opioid for pain management in the postanesthesia care unit or postsurgical floors.

Background: Pregabalin supplementation may have some potential in improving pain relief in patients with septorhinoplasty, and this meta-analysis aims to explore the impact of pregabalin supplementation on pain control for septorhinoplasty. Methods: PubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of pregabalin supplementation on pain control for septorhinoplasty. Results: Six RCTs were finally included in the meta-analysis. Overall, when compared with control intervention for septorhinoplasty, pregabalin intervention showed significantly reduced pain scores at 1 h (SMD − 1.05; 95% CI − 1.85 to − 0.24; P = 0.01), 2 h (SMD − 1.01; 95% CI − 1.83 to − 0.20; P = 0.02), 6 h (SMD − 1.00; 95% CI − 1.47 to − 0.54; P < 0.0001) and 12 h (SMD − 0.69; 95% CI − 1.35 to − 0.02; P = 0.04), as well as rescue analgesics (OR 0.17; 95% CI 0.07 to 0.44; P = 0.0002), but had no notable influence on nausea and vomiting (OR 0.67; 95% CI 0.30 to 1.46; P = 0.31), or drowsiness (OR 1.22; 95% CI 0.64 to 2.35; P = 0.54). Conclusions: Pregabalin supplementation benefits to pain control after septorhinoplasty. [ABSTRACT FROM AUTHOR]

(Case 1) A 45-year-old male was diagnosed with prostate cancer. Treatment was administered using bicalutamide and leuprorelin acetate, while a transdermal fentanyl (TDF) was applied for pain relief. However, TDF continued to peel off owing to excessive sweating, even when reinforced by a protective layer. As such, TDF was discontinued and pain control was initiated using other medicines. Sweating occurred irregularly because of hot flashes, approximately four to five times per day. (Case 2) A 37-year-old male was diagnosed with a malignant thymoma and sacral metastasis. For analgesic control, etodolac tablets, carbamazepine tablets, and TDF were administered. Subsequently, the dose of the TDF was gradually increased, but the analgesic effect was low; thus, fentanyl blood concentration was measured. The measurements showed that even higher TDF doses did not increase fentanyl blood levels. During this period, full body sweating began to occur to a large extent due to unknown causes, and it was thought that the absorption of fentanyl decreased. When using a TDF, it is necessary to monitor patients for any sweating during treatment, while also considering changes in medication in some cases. This should promote the maintenance and improvement of the quality of life of the affected patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: Although the biomechanical features of the golf swing are extremely determined, multiple joint movements with limited pelvic and thoracic rotation movement can cause injury to the golfer and are linked with low back pain (LBP). We have developed the Pulley Master machine (PM), which is designed to offer active movement evaluation and monitoring as well as repetitive and task-specific training. OBJECTIVE: The primary goal of the present research was to analyze the effects of PM and Transfer of Electricity-Capacitive and Resistive (TECAR) therapy on the lumbar pain scale and thoracic and pelvic mobility in amateur golfers with LBP. METHODS: Twenty-one amateur golfers with LBP (six females, mean age = 23.43 ± 2.36 years) were randomly assigned to either PM or TECAR groups for five days per week over one week. Clinical outcome measurements included pelvic and thoracic mobility as well as a pain rating scale. Statistical analyses were presented using the analysis of variance (ANOVA), and the statistical significance level was set at P < 0.05. RESULTS: ANOVA showed that PM outperformed TECAR in terms of pelvic and thoracic mobility as well as a pain rating scale. CONCLUSION: The results provide novel and encouraging clinical evidence that PM improves pain control and mobility in amateur golfers with LBP. [ABSTRACT FROM AUTHOR]

Background: Laser hair removal is associated with moderate acute pain.Objective: To compare effectiveness of ice pack to topical lidocaine-prilocaine for pain reduction during axillary laser hair removal.Methods: Participants were randomly assigned to receive topical anesthetic to one axilla and ice packs to the other before each of three, monthly 810-nm diode laser sessions. The primary endpoint was participant-reported pain on the visual analog scale (VAS) immediately following and 5 minutes after laser. Post-treatment erythema, overall edema, and perifollicular edema were assessed by two blinded photoraters. Skin temperatures, patient preferences, and adverse events were recorded.Results: Eighty-eight of 90 (98%) planned laser treatments were delivered, and randomized. Participants reported higher VAS scores immediately after laser with lidocaine-prilocaine compared to ice (p=0.03). Five minutes after, participants reported higher VAS scores with ice (p=0.03). After 53 of the 88 treatments (60.2%), participants reported preferring ice (p=0.055). No serious adverse events were reported.Limitations: All participants were Caucasian or Asian with Fitzpatrick skin type I-III and coarse dark axillary hair, which may limit generalizability.Conclusions: While pain control with ice and topical anesthesia is associated with time after treatment, the two modalities do not differ in terms of degree of pain reduction associated with axillary laser hair removal.

Original Research. To comparatively evaluate the effect of different premedication agents on the efficacy of 4% Articaine in teeth with symptomatic irreversible pulpitis. The primary objective of our study is to evaluate the effect of premedication agents on efficacy of Articaine as an oral anesthetic. Our secondary objective is to comparatively evaluate the efficacy of Diclofenac patch, Ibuprofen tablet, Paracetamol tablet and Placebo as a premedication agent. Patients with 25–40 years age, no systemic disease, no history of medication for that complaint, with pain on Heft Parker Visual Analog Scale between 55 mm and 170 mm (VAS), no tenderness on percussion, cold test and EPT negative- Positive, giving proper consent, coming to the Department of Conservative Dentistry and Endodontics were allowed to participate. The exclusion criteria include the following- Non-vital teeth, pregnant and lactating women, allergic to Articaine and NSAIDs, active systemic disease, immune-compromised patients, taken analgesics in last 24 h, root fractures, restoration extending to pulp10 and periapical pathologies (except periodontal ligament widening). Preoperatively pain was recorded using Heft Parker VAS (Visual Analog Scale). Cold testing, palpation, percussion and EPT were carried out. 40 patients having symptomatic irreversible pulpitis were randomly divided into 4 groups: group 1 Placebo (n = 10), group 2-Diclofenac patch (n = 10), group-3 Ibuprofen tablets (n = 10), group 4-Paracetamol tablets (n = 10). After 1 h of premedication, all patients were administered IANB injection using 4% Articaine (Septanest with adrenaline 1/100000, Septodont, France) containing epinephrine 1:100000. 15 mins after administration of IANB, patients were asked about symptomatic numbness and was tested with Endo frost and EPT and Outcome was recorded. If lip numbness was present, Electric Pulp Testing and Cold Test give negative result then endodontic access opening was performed and pain was recorded using visual analog scale. The study was conducted for a period of 1.5 years. During the access cavity preparation only 1 subject in the Group III reported pain while in other groups none of the subjects reported pain of any type. When the intergroup comparison was made of intensity of pain 15 min after LA and during access cavity preparation, the difference between the groups was statistically non-significant when analyzed using One Way ANOVA. The intragroup comparison between three time intervals revealed significant reduction in the pain scores from the pre-treatment levels in all the four groups. The results of the study showed that there is no significant effect of different premedication agents on the efficacy of 4% Articaine in teeth with symptomatic irreversible pulpitis.

Context: Over 20% of US adults report they experience pain on most days or every day. Uncontrolled pain has led to increased healthcare utilization, hospitalization, emergency visits, and financial burden. Recognizing, assessing, understanding, and treating pain using artificial intelligence (AI) approaches may improve patient outcomes and healthcare resource utilization. A comprehensive synthesis of the current use and outcomes of AI-based interventions focused on pain assessment and management will guide the development of future research.Objectives: This review aims to investigate the state of the research on AI-based interventions designed to improve pain assessment and management for adult patients. We also ascertain the actual outcomes of Al-based interventions for adult patients.Methods: The electronic databases searched include Web of Science, CINAHL, PsycINFO, Cochrane CENTRAL, Scopus, IEEE Xplore, and ACM Digital Library. The search initially identified 6946 studies. After screening, 30 studies met the inclusion criteria. The Critical Appraisals Skills Programme was used to assess study quality.Results: This review provides evidence that machine learning, data mining, and natural language processing were used to improve efficient pain recognition and pain assessment, analyze self-reported pain data, predict pain, and help clinicians and patients to manage chronic pain more effectively.Conclusions: Findings from this review suggest that using AI-based interventions has a positive effect on pain recognition, pain prediction, and pain self-management; however, most reports are only pilot studies. More pilot studies with physiological pain measures are required before these approaches are ready for large clinical trial. [ABSTRACT FROM AUTHOR]

ABSTRACT: Background: Recently, there has been increasing legalization of marijuana within the United States, however data are mixed with respect to its efficacy in treating acute pain. Our goal was to identify a difference in opioid utilization in patients with known cannabis use before anterior cervical discectomy and fusion (ACDF) compared with those that report no cannabis use. Methods: This study was a retrospective case-control design using PearlDiver. Patients who underwent a single level ACDF between January 2010 and October 2020, were included. Patients were placed in the study group if they had a previous diagnosis of cannabis use, dependence, or abuse. Patients were excluded if they were under the age of 18 or if they had filled an opioid prescription within 3 months of their procedure. A control group was then created using a propensity score match on age, gender, and Charleston comorbidity index (CCI), and had no diagnosis of cannabis use. The primary outcome was the number of morphine milliequivalents (MME) dispensed per prescription following surgery. Results: A total of 1,339 patients were included in each group. The number of patients filling prescriptions was lower in the cannabis group than in the control group at 3 days postoperatively (p

The objectives of this study were to assess the pharmacokinetics and pharmacodynamics of the current standard-of-care for pain mitigation in lambs during castration and tail docking (injectable lidocaine) and assess the ability of Lidocaine-Loaded Bands (LLBs) to deliver therapeutic concentrations into the contacted tissues over time. The study was comprised of four different trials: (1) investigation of in vitro release of lidocaine from LLBs; (2) pharmacokinetics and pharmacodynamics of injectable lidocaine in scrotal and tail tissue; (3) pharmacokinetics and pharmacodynamics of in vivo delivery of lidocaine with LLBs placed on the tail and scrotum of lambs; and (4) a “proof-of-concept” study comparing the sensation of control- versus LLB-banded tail tissue over time. The use of injectable lidocaine provides effective short-term anesthesia for 120 to 180 min following the injection; however, additional strategies are needed to manage long-term pain. The use of an LLB could provide an alternative where tissue lidocaine concentrations meet or exceed the EC50 for at least 21–28 days and, based on electrostimulation data, provides local anesthesia for at least 3 days when compared to a control band. Further studies are needed to compare the use of an injectable local anesthetic to the LLBs.

Purpose: Patients undergoing hematopoietic stem cell transplantation (HSCT) are at high risk of oral complications with the potential of causing significant morbidity and mortality. Dental professionals should play a fundamental role in the prevention and treatment of oral sequelae of HSCT. However, the dental community is not well informed and experienced in providing oral care of the oral complications for HSCT patients. This narrative review attempts to fill the knowledge gap through reviewing the oral complications and current recommendations for oral and dental care for the patient before, during and after HSCT.Results: Oral care in the HSCT process was divided into five stages with the goal being to provide practical guidance for dental care providers to assist in managing these patients. It is well known that the maintenance of good oral health is important in cancer patients, including patients with hematologic malignancies. In addition to negatively impacting quality of life, oral pain and/or infections can cause delays, modification and discontinuation of life-saving cancer treatment. Oral complications can lead to new or extended hospitalization. By providing a preventive and treatment algorithm based on currently available literature reports and expert opinion, we can hope to achieve better patient outcomes.Conclusion: We present oral and dental management recommendations with a focus on oral health maintenance, infection prevention, pain control and oral complication management to support oral and general health of this medically complex patient population prior to, during and following HSCT.

ObjectivesThe aim of this study was to evaluate the impact of epidural analgesia (EA) on postoperative length of stay (LOS), expeditious discharge, and pain relief after pancreaticoduodenectomy (PD) and distal pancreatectomy (DP).MethodsRetrospective reviews of 2014-2015 American College of Surgeons National Surgical Quality Improvement Program databases and our institutional pancreatic surgery database were conducted.ResultsOn univariate analysis, EA was associated with statistically significant longer lengths of stay for both PD and DP. On comparative analysis at mode LOS, discharged before versus after 7 days for PD and 6 days for DP, EA was a significant predictor for the longer groups for both procedures on multivariable analysis (PD, odds ratio of 1.465, P < 0.001; DP, odds ratio of 1.471, P = 0.004). On review of our institution's pancreatic surgery database, patient-reported pain scores were significantly lower in the EA groups than intravenous narcotics groups on the day of surgery only for both PD and DP.ConclusionsEpidural analgesia was associated with longer LOS with a most pronounced effect on early discharge after surgery for patients undergoing open PD and DP. It only resulted in superior pain control on the day of surgery.

To date, there is still no consensus regarding its rehabilitative treatment for pain management.Purpose: The aim of this umbrella review of systematic reviews was to analyze the literature, investigating the effects of non-surgical and rehabilitative interventions in patients suffering from FS.Patients and Methods: A review of the scientific literature was carried out from 2010 until April 2020 using the following search databases: PubMed, Medline, PEDro, Scopus and Cochrane Library of Systematic Reviews. A combination of terms was used for the search: frozen shoulder OR adhesive capsulitis AND systematic review OR meta-analysis AND rehabilitation NOT surgery NOT surgical intervention. We included systematic reviews that specifically dealt with adults with FS, treated with non-surgical approaches. All the systematic reviews and meta-analyses included in the study that met the inclusion criteria were assessed using the Assessment of Multiple Systematic Reviews as a quality assessment tool.Results: Out of 49 studies, only 14 systematic reviews respected the eligibility criteria and were included in this study. Their results showed an important heterogeneity of the studies and all of them agree on the lack of high-quality scientific work to prove unequivocally which rehabilitative treatment is better than the other. Due to this lack of gold standard criteria, there may be also a heterogeneity in the diagnosis of the reviews analyzed.Conclusion: Non-surgical and rehabilitative interventions are undoubtedly effective in treating FS, but there is no evidence that one approach is more effective than the other regarding the methods reported. Future high-quality RCTs are needed to standardize the treatment modalities of each physiotherapy intervention to provide strong recommendations in favor.Keywords: adhesive capsulitis, frozen shoulder, pain control, pain management, rehabilitation, non-surgical interventions

Objective This study aimed to observe the analgesic effect of the cocktail formulation with diprospan during total hip arthroplasty (THA). Methods From September 2018 to April 2019, 120 patients undergoing primary unilateral THA were included in this prospective, randomized, observer‐blinded study. Patients were randomized into three groups, according to the different local infiltration analgesia (LIA) strategies: LIA with ropivacaine (the ropivacaine group, n = 40), LIA with a new cocktail containing ropivacaine, diprospan, and morphine (the cocktail group, n = 40), and the control group (n = 40). The primary outcomes included postoperative pain scores. The resting visual analogue scale (VAS) scores were measured at 2, 6, and 12 h after the surgery (a.m. and p.m.) on postoperative day (POD) 1, POD2, and the day of discharge. Movement VAS scores were assessed at 6 h, 12 h after the operation (a.m. and p.m.) on POD1, POD2, and the day of discharge. The secondary outcomes included opioid consumption, postoperative hospital stay, range of motion of the hip at discharge, patient satisfaction, and the results of the follow‐up. Results After the screening, 120 patients were randomized into three groups (40 patients in each group). All of the patients completed the trial. The resting VAS scores in the ropivacaine group and cocktail group at 2 h were lower than those in the control group (P

Abstract Background Patients with bone metastasis often experience severe pain that is difficult to control and seriously affects quality of life. Radiotherapy is an effective way to relieve pain in these patients. Currently, there is no standard recommended range of radiotherapy targets for vertebral metastasis. The effect of radiotherapy on pain relief varies among patients, and some patients with metastases have serious side effects. Methods This study aims to verify whether reducing the radiotherapy range for vertebral metastases can achieve the same effect as whole vertebral radiotherapy while minimizing side effects. Sixty-six patients with pain caused by vertebral metastasis were randomly divided into two groups. The study group is receiving partial vertebrae body radiotherapy at the regions of abnormal signal, suspected invasion, and adjacent subclinical focus of vertebral metastasis, and the control group is receiving the same dose of radiotherapy on whole vertebrae body where metastasis occurred. After radiotherapy, along-term follow-up of patients will determine pain relief and side effects. Discussion The expected results of this study are that local irradiation of vertebral metastases can achieve a palliative effect of pain control not less than total vertebral irradiation with fewer side effects. Trial registration This study was registered in the Chinese Clinical Trial Registry (No: ChiCTR1900023401 ).
