Background: Various analgesic techniques have been applied, the pain after video assisted thoracic surgery (VATS) is still challenging for anesthesiologists. Paracetamol provide analgesic efficacy in many surgeries. However, clinical evidence in the lung surgery with regional block remain limited. This monocentric double-blind randomized controlled trial investigates the efficacy of paracetamol after VATS with regional block. Methods: A total of 90 patients were randomized to receive paracetamol (1 g) or normal saline. Erector Spinae Plane Block and Intercostal Nerve block were applied during the surgery. The Visual Analogue Scales (VAS) pain score was measured in the PACU as well as 6, 12, 24, and 48 h postoperatively. And the total dose of rescue analgesics administered to patients in morphine milligram equivalents (MME), satisfaction score, length of hospital stays, and incidence of nausea and vomiting were also recorded. Results: The VAS pain score at each time point, the primary endpoint, did not differ between the groups (3.09 ± 2.14 vs. 2.53 ± 1.67, p = 0.174 at PACU; 4.56 ± 2.80 vs. 4.06 ± 2.46, p = 0.368 at 6 h; 3.07 ± 1.98 vs. 3.44 ± 2.48, p = 0.427 at 12 h; 2.10 ± 2.00 vs. 2.49 ± 2.07, p = 0.368 at 24 h; and 1.93 ± 1.76 vs. 2.39 ± 1.97, p = 0.251 at 48 h postoperatively). Satisfaction scores (4.37 ± 0.76 vs. 4.14 ± 0.88, p = 0.201), nausea (35.6% vs. 37.8%, p = 0.827), hypotension (2.2% vs. 0.0%, p = 0.317), and bradycardia (6.7% vs. 2.2%, p = 0.309) were also reported at similar rates. Conclusions: The analgesic efficacy of one gram of paracetamol with ESPB and ICNB after VATS was not proven. Thus, caution should be exercised when prescribing paracetamol for pain control during VATS. Trial registration: this trial was registered on Clinical Research Information Service (CRIS), Republic of Korea (KCT0008710). Registration date: 17/08/2023. [ABSTRACT FROM AUTHOR]

Thoracic discectomy procedures require early and adequate pain control to alleviate patient discomfort after surgery. The intraoperative placement of a nerve block after intercostal nerve violation can offer early pain management after thoracic discectomy. The anatomy and technique of placing an intercostal nerve block after retropleural thoracic discectomy are described. Patient data were collected for patients who underwent this technique. This approach is presented with an illustrative figure and a review of relevant anatomical landmarks to describe the technique and ensure its reproducibility. Data for 93 patients (57 [61%] women; 36 [39%] men; mean [SD] age, 54.1 [14.1] years) who underwent the procedure are provided to assess the reliability of this technique. Intercostal nerve blockage offers a valuable addition to postoperative pain management and may be considered as an available pain relief option for patients undergoing thoracic discectomy.

Purpose: Patients undergoing thoracic surgery suffer from severe postoperative pain, and a series of complications will occur if there is no effective analgesic treatment. Liposomal bupivacaine (LB) is a novel multivesicular formulation with up to 72 hours of analgesia, which can be used in thoracic surgery. This meta-analysis aimed to evaluate the efficacy of LB in improving recovery in patients undergoing thoracic surgery compared with non-liposomal local anesthetics. Patients and Methods: A literature search was conducted using PubMed, Cochrane Library, Embase, and Web of science, and to identify all observational or retrospective studies and randomized controlled trials (RCTs) from inception to December 2023. The primary outcome was the in-hospital postsurgical opioid consumption in morphine milligram equivalents (MMEs). Secondary outcomes included 24-hour postoperative MMEs, postoperative pain score in the first 24 and 48 hours, hospital length of stay (LOS), time to first ambulation, readmission, and perioperative complications. RevMan 5.3 was used for the data analysis. Results: A total of 10 studies were included in the analysis, of which eight were observational or retrospective analyses and two were RCTs. There were no significant differences in the postoperative MMEs, pain score, LOS, time to first ambulation, readmission, and perioperative complications. Conclusion: According to this meta-analysis, LB was found to be not superior to non-liposomal local anesthetics for analgesic and functional outcomes in thoracic surgery. [ABSTRACT FROM AUTHOR]

To explore the effect of scalp nerve block (SNB) combined with intercostal nerve block (ICNB) on quality of recovery (QoR) after deep brain stimulation (DBS) in patients with Parkinson's disease (PD). Methods: We conducted a prospective randomized controlled trial in which 88 patients with PD were randomly assigned to undergo SNB combined with ICNB (SNB group) or not (control group) before surgery. The primary outcome was the 15-item QoR (QoR-15) score 24 h after surgery. The secondary outcomes included QoR-15 scores at 72 h and 1 month after surgery, pain-related events, recovery events in post-anesthesia care unit (PACU), duration of anesthesia and surgery, and nerve block-related adverse events. Results: The QoR-15 score at 24 h after surgery was significantly higher in SNB group than Control group: 122.0 ± 7.6 vs 113.5 ± 11.3 (P = 0.006). SNB combined with ICNB improved QoR-15 scores at 72 h (P = 0.004) but not at 1 month after surgery (P = 0.230). The SNB group was positively related to QoR-15 scores 24 h after surgery (β = 8.92; 95% CI = 4.52~13.32) after adjusting for confounding variables. The numeric rating scale pain scores at PACU discharge and at 24 h, intraoperative opioid consumption, rescue analgesic use, and the incidence of postoperative nausea and vomiting (PONV) in SNB group were significantly lower than Control group (P < 0.05). Conclusion: Preoperative SNB combined with ICNB improved QoR and analgesia after surgery, and reduced intraoperative opioid consumption and the incidence of PONV in patients with PD who underwent DBS.

Abstract Objective The purpose of this study was to compare the analgesic effects of intercostal nerve block (ICNB) and local anesthetic infiltration (LAI) on postoperative pain and recovery following thoracoscopic resection of pulmonary bullae. Methods A total of 160 patients undergoing thoracoscopic pulmonary bullae resection were randomly assigned to receive either ICNB (n = 80) or LAI (n = 80). An experienced anesthesiologist administered ultrasound guided ICNB at the T4 and T7 levels with 5 mL of 0.375% ropivacaine hydrochloride for the ICNB group. Instead, the LAI group received 10 mL of the same concentration of ropivacaine hydrochloride at the same concentration used for ICNB for infiltration anesthesia at the incision sites. Out of the initial cohort, 146 patients completed the study (ICNB group, n = 71; LAI group, n = 75). The collected data included preoperative clinical characteristics, visual analog scale (VAS) scores for pain at various time points post-surgery (6, 12, 24, 48, and 72 h). Additionally, the Quality of Recovery-15 (QoR-15) questionnaire was administered 24 h after surgery, and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). Results No significant differences were found in drainage volume, use of additional analgesics, duration of chest tube placement, or hospital stay between the two groups. However, the ICNB group had significantly lower VAS scores and QoR-15 scores 24 h postoperatively (p

Abstract Background Opioid-reduced multimodal analgesia has been used clinically for many years to decrease the perioperative complications associated with opioid drugs. We aimed to assess the clinical effects of opioid-reduced anesthesia during thoracoscopic sympathectomy. Methods Surgical patients (n = 151) with palmar hyperhidrosis were randomly divided into control (Group C, 73 patients) and test (Group T, 78 patients) groups. All patients were administered general anesthesia using a laryngeal mask. In Group C, patients received propofol, fentanyl, and cisatracurium for anesthesia induction, and maintenance was achieved with propofol and remifentanil, along with mechanical ventilation during the operation. In Group T, anesthesia was induced with propofol, dezocine, and dexmedetomidine (DEX) and maintained with propofol, DEX, and an intercostal nerve block, along with spontaneous breathing throughout the operation. Perioperative complications related to opioid use include hypotension, bradycardia, hypertension, tachycardia, hypoxemia, nausea, vomiting, urine retention, itching, and dizziness were observed. To assess the impact of these complications, we recorded and compared vital signs, blood gas indices, visual analogue scale (VAS) scores, adverse events, and patient satisfaction between the two groups. Results Perioperative complications related to opioid use were similar between groups. There were no significant differences in the type of perioperative sedation, analgesia index, respiratory and circulatory indicators, blood gas analysis, postoperative VAS scores, adverse reactions, propofol dosage, postoperative recovery time, and patient satisfaction. Conclusions In minimally invasive surgeries such as thoracoscopic sympathectomy, opioid-reduced anesthesia was found to be safe and effective; however, this method did not demonstrate clinical advantages.

Abstract Background Thoracoscopic-guided thoracic paravertebral nerve block (TG-TPVB) and thoracoscopic-guided intercostal nerve block (TG-INB) are two postoperative analgesia technology for thoracic surgery. This study aims to compared the analgesic effect of TG-TPVB and TG-INB after uniportal video-asssited thoracic surgery (UniVATS). Methods Fifty-eight patients were randomly allocated to the TG-TPVB group and the TG-INB group. The surgical time of nerve block, the visual analog scale (VAS) scores, the consumption of sufentanil and the number of patient-controlled intravenous analgesic (PCIA) presses within 24 h after surgery, the incidence of adverse reactions were compared between the two groups. Results The VAS scores were significantly lower during rest and coughing at 2, 6, 12, and 24 h in the TG-TPVB group than in the TG-INB group (P

Backgrounds: To observe the effect of ropivacaine intercostal nerve block combined with PCIA as early postoperative analgesia following breast augmentation surgery with prosthesis (axillary approach) Methods: A total of 80 women with breast augmentation surgery were selected in the plastic surgery department of Chongqing Huamei Plastic Surgery Hospital from December 2021 to May 2022. They were equally randomized into control group and observation group, with 40 cases in each one. Before placing the prosthesis, the control group was given 0.9% normal saline for intercostal nerve block; the observation group was given 0.75% ropivacaine + 1‰ adrenaline for intercostal nerve block. Patient controlled intravenous analgesia (PCIA) was used after operation. Observation indexes the visual analog scale (VAS) of resting and motor state at 4 h, 24 h, 48 h and 72 h after operation and the adverse reactions. Results: The VAS scores of patients at rest and exercise and adverse reactions in the observation group were lower than those in the control group (P<0.05). Conclusion: Ropivacaine intercostal nerve block combined with PCIA can effectively alleviate the pain after breast augmentation with pectoralis major prosthesis through axillary incision, help patients more comfortably through the perioperative period, accelerate postoperative recovery, reduce the dosage of systemic opioids and effectively reduce side effects.

The incidence of bleeding at the puncture point was lower in the TG-TPVB group than that in the TG-INB group (P < 0.05). Conclusion: TG-TPVB demonstrated superior acute pain relieve after uniVATS, shorter surgical time and non-inferior adverse effects than TG-INB. [ABSTRACT FROM AUTHOR]

Abstract Objective In this study, we compared the analgesic effects of intercostal nerve block (ICNB), ultrasound-guided paravertebral nerve block (PVB), and epidural block (EB) following single-port thoracoscopic lung surgery. Method A total of 120 patients who underwent single-hole thoracoscopic lung surgery were randomly and equally divided into three groups: ICNB group, the PVB group, and the EB group. ICNB was performed under direct thoracoscopic visualization before the conclusion of the surgery in the ICNB group, while PVB and EB were performed after general anesthesia in the PVB and EB groups, respectively. Patient-controlled intravenous analgesia (PCIA) was used following the surgery in all the groups. The following indicators were recorded: Intraoperative sufentanil dosage, anesthesia awakening time, postoperative intubation time, nerve block operation time, postoperative visual analog scale (VAS) pain scores during resting and coughing at regular intervals of 0, 2, 4, 8, 24, and 48 h, the time until first PCIA, number of effective compressions within 24 h postoperatively, number of rescue analgesia interventions, and the side effects. Results In comparison to the ICNB group, the PVB and EB groups had a lower intraoperative sufentanil dosage, significantly shorter anesthesia awakening time, and postoperative intubation time, but longer nerve block operation time, lower VAS scores when resting and coughing within 24 h postoperatively (all p-values less than 0.05). Conversely, there were no statistically significant differences in VAS scores during resting and coughing after 24 h (all p-values greater than 0.05). Time to first PCIA, number of effective compressions and number of rescue analgesia at the 24-hour mark postoperatively were significantly better in the PVB and EB groups than that in the ICNB group (P

Objective: To explore the postoperative analgesic effect and patient recovery of intercostal nerve block combined with general anesthesia and patient-controlled intravenous analgesia in thoracoscopic bullectomy. Methods: The subjects were selected from80 patients who underwent thoracoscopic bullectomy. They were divided into control group and observation group according to simple digital table method, with 40 patients in each group. The control group received general anesthesia combined with patient-controlled intravenous analgesia, and the observation group combined with intercostal nerve block on this basis to compare the postoperative analgesia effect and recovery of the two groups. Results: Compared with pre-operation, the CD4+ and CD4+/CD8+ of patients in the two groups decreased at first and then increased at 24 hours after operation, and the observation group was higher than the control group at all time points; The CD8+of patients in both groups increased first and then decreased, and the observation group was lower than the control group at all time points (P＜0.05) . At 24 and 48 hours after operation, the number of analgesic pump pressure and the total amount of analgesic drug infusion in the observation group were decreased compared with the control group (P＜0.05) . Compared with the control group, the time from the end of operation to extubation, the time to get out of bed and the time to stay in hospital were shorter in the observation group (P＜0.05) . Compared with the control group (22.50%, 20.00%), the total incidence of complications and adverse reactions in the observation group (2.50%, 5.00%) was lower (P＜0.05) . Conclusion: The application of intercostal nerve block combined with general anesthesia combined with patient-controlled intravenous analgesia in thoracoscopic bullectomy has achieved remarkable analgesic effect, which can not only reduce the postoperative pain of patients, but also reduce the body’s immunosuppression, without increasing the risk of complications and adverse reactions. The clinical application is safe. [ABSTRACT FROM AUTHOR]

Introduction: Autologous costal cartilage harvest is a common procedure in craniofacial reconstruction due to its stability, dependability, and diversity. However, such a procedure is associated with severe donor-site pain postoperatively. Therefore, we aim through this study to compare the efficacy of intercostal nerve block in the management of postoperative pain in patients undergoing costal cartilage harvest for craniofacial reconstruction. Method: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The study systematically reviewed MEDLINE, Cochrane, and EMBASE databases without time-limitation. Results: As a result of reviewing the literature, 33 articles were screened by full-text resulting in 14 articles which met our inclusion/exclusion criteria. However, only four high-quality RCT articles were included in the quantitative synthesis (meta-analysis). The findings of this study suggest that there is no significant difference in pain scores between ICNB and control groups at 12, 24, and 48 h postoperatively, both at rest and with coughing. Therefore, both techniques are considered safe and effective. Conclusion: Our results show evidence of favorable outcome of preventive donor-site analgesia with ICNB for harvesting autologous costal cartilage in multiple studies. However, the overall outcomes were insignificant between the two arms.

Objectives: Postthoracotomy pain requires multimodal perioperative management, including systemic and regional techniques. This prospective, randomized study aimed to evaluate postthoracotomy pain scores using the visual analog scale (VAS) as well as consumption of analgesic in 24 h and complications. Methods: The patients were randomly assigned into four groups (25 patients each group) according to the analgesia technique used: Intercostal nerve block (ICB), thoracic epidural block (TEB), ultrasonography-guided erector spinae plane block (ESPB), and ultrasonography-guided thoracic paravertebral block (TPVB) groups. Multimodal analgesia was achieved with tramadol, paracetamol, and intravenous pethidine via patient-controlled analgesia (PCA) for all patients. The VAS scores at 30,60,90,120 min, 6,12, and 24 h postoperatively, consumption of analgesic at the first 24 h, rescue analgesic requirement, and side effects were recorded. Results: The VAS scores were the highest in the ICB group and the lowest in the TPVB group at all time periods after thoracotomy (p<0.05). Likewise, total pethidine dose, number of PCA trials, and PCA data were determined to be at least in the TPVB group. However, only the number of PCA trials was found to be statistically significant (p=0.03). In terms of side effects, no difference was observed between the groups. Nausea and vomiting occurred in two patients in the ICB and ESPB groups, whereas hypotension occurred in two patients in the TEB group. Conclusion: In conclusion, ultrasound-guided single-injection TPVB is more reliable and preferable in thoracotomy, as it is associated with low pain scores and has no side effects.

Abstract Background This study aimed to compare the analgesic efficacy of transthoracic intercostal nerve block (TINB) and percutaneous intercostal nerve block (PINB) for video-assisted thoracic surgery (VATS) using a retrospective analysis. Methods A total of 336 patients who underwent VATS between January 2021 and June 2022 were reviewed retrospectively. Of the participants, 194 received TINB and were assigned to the T group, while 142 patients received PINB and were assigned to the P group. Both groups received 25 ml of ropivacaine via TINB or PINB at the end of the surgery. The study measured opioid consumption, pain scores, analgesic satisfaction, and safety. Propensity score matching (PSM) analysis was performed to minimize selection bias due to nonrandom assignment. Results After propensity score matching, 86 patients from each group were selected for analysis. The P group had significantly lower cumulative opioid consumption than the T group (p 0.05). The analgesic satisfaction in the P group was higher than in the T group (p 0.05). Conclusion The study suggests that PINB provides superior analgesia for patients undergoing thoracic surgery compared to TINB without any extra adverse effects.

Objective: Implementation and continuing optimization of enhanced recovery protocol after thoracic surgery results in significant improvement of postoperative outcomes. We observed a 10-fold increase in the rate of postoperative day (POD) 1 discharges following robotic thoracoscopic anatomic resections over time. We aimed to determine factors associated with safe POD1 discharges. Methods: We performed a retrospective analysis of a prospectively maintained database of robotic anatomic pulmonary resections between July 1, 2012, and June 30, 2022, with patients of the last 2.5 years forming the basis of this study. Data collected included demographics, insurance types, Area Deprivation Index (indicator of poverty), and operative and postoperative variables including length of stay, opioid use, daily pain levels, readmissions, and outpatient interventions. Factors associated with POD1 were analyzed using a logistic regression module. Result: In total, 279 patients met inclusion criteria (91 POD1 discharges, 32.6%; none discharged with a pleural catheter). There was neither an increase of postdischarge interventions for pleural complications nor readmission in early discharge patients. After adjusting for relevant factors, younger age, right middle lobectomy, lower opioid use on POD1, operating room finish before 4 PM, and low Area Deprivation Index were significantly associated with POD1 discharge. A subanalysis of 49 patients, who could have been discharged on POD1, identified hypoxemia requiring home oxygen, atrial fibrillation, and poorly controlled pain being common mitigatable clinical factors delaying POD1 discharge. Conclusions: Safe POD1 discharge following robotic thoracoscopic anatomic resection was achieved in 32% of cases. Identification of positive and negative factors affecting early discharge provides guidance for further modifications to increase the number of POD1 discharges.

Objectives: Enhanced recovery after thoracic surgery (ERATS) protocols use a combination of analgesics for pain control and have been associated with decreased opioid requirements. We investigated the impact of continual ERATS refinement on the incidence of opioid-free discharge. Methods: We retrospectively analyzed our prospectively maintained institutional database for elective, opioid-naive robotic thoracoscopic procedures. Demographics, operative outcomes, postoperative opioid dispensed (morphine milligram equivalent), and opioid discharge status were collected. Our primary outcome of interest was factors associated with opioid-free discharge; our secondary objective was to determine the incidence of new persistent opioid users. Results: In total, 466 patients from our optimized ERATS protocol were included; 309 (66%) were discharged without opioids. However, 34 (11%) of patients discharged without opioids required a prescription postdischarge. Conversely, 7 of 157 patients (11%), never filled their opioid prescriptions given at discharge. Factors associated with opioid-free discharges were nonanatomic resections, mediastinal procedures, minimal pain, and lack of opioid usage on the day of discharge. More importantly, 3.2% of opioid-free discharge patients became new persistent opioid users versus 10.8% of patients filling opioid prescriptions after discharges (P = .0013). Finally, only 2.3% of opioid-naive patients of the entire cohort became chronic opioid users; there was no difference in the incidence of chronic use by opioid discharge status. Conclusions: Optimized opioid-sparing ERATS protocols are highly effective in reducing opioid prescription on the day of discharge. We observed a very low rate of new persistent or chronic opioid use in our cohort, further highlighting the role ERATS protocols in combating the opioid epidemic.

A recent trend in postoperative analgesia for lung cancer surgery relies on regional nerve blocks with decreased opioid administration. Our study aims to critically assess the continuous ultrasound-guided erector spinae plane block (ESPB) at our institution and compare it to a standard regional anesthetic technique, the intercostal nerve block (ICNB).

Introduction: The most often utilized flank approach in renal surgery is through the bed of the 11th or 12th rib, which offers excellent exposure to the renal parenchyma and collecting system [1]. The patient response to pain and surgery, and pre/peri-operative analgesic techniques all play a role in enhancing post-operative discomfort. The goal of this study was to compare the effectiveness of intercostal nerve block with flank incision infiltration of local anesthetics such as 0.25% Bupivacaine on postoperative pain control in order to determine which method was the most effective in reducing the need for total analgesic consumption. Methods: The study included a total of 100 individuals who underwent elective flank incision surgeries between January 2021 and January 2023 in our hospital: Two surgeons performed the procedures; one frequently employed infiltration of the flank incision while the second always used intercostal block on all of his patients. After reviewing the patient's medical records, we divided them into two groups: group A-50 patients who underwent intraoperative incisional infiltration (ICI) of combined local anesthetic agents (0.5% bupivacaine (20ml) + 2% lidocaine (5ml) diluted in 15ml 0.9% normal saline solution; and group B-50 patients, Intercostal nerve block (ICNB) during surgery using the same anesthetic agent. Postoperative pain scores were calculated up to the third day of surgery. Result: The patients ranged in age from 15 to 75 years. On comparison of postoperative pain on the visual analogue scale group A had better pain scores at the recovery period and postoperatively on day 3 which was statistically significant (Table 2). In conclusion, wound infiltration is preferred over the intercostal nerve block in terms of the analgesic aspect, and its use is recommended postoperatively in major urological procedures.

Abstract The letter to the editor was written in response to “The effect of ultrasound-guided intercostal nerve block on postoperative analgesia in thoracoscopic surgery: a randomized, double-blinded, clinical trial”, which was recently published by Li et al. (J Cardiothorac Surg 18(1):128, 2023). In this article, Li et al. showed that addition of a preoperative intercostal nerve block to the multimodal analgesic strategy significantly reduced the pain scores within 48 h after surgery. However, we noted several issues in this study that were not well addressed. They were no use of a standard opioid-sparing multimodal analgesic strategy recommended in the current Enhanced Recovery After Surgery protocols for thoracic surgery, the lack of clear description for reasonable selection of rescue analgesics, the interpretion of between-group differences in the postoperative pain scores based on only statistical differences rather than clinically meaningful differences, inclusion of patients who were not blinded to study intervention, not reporting cumulative opioid consumption and complications of intercostal nerve block. We believe that clarification of these issues is not only useful for improving design quality of randomized clinical trials which assess postoperative analgesic efficacy of nerve blocks, but also is helpful for the readers who want to use an opioid-sparing multimodal protocol including a nerve block in patients undergoing thoracoscopic surgery.

After MINB was performed in both groups at the end of the surgery, the intervention group received patient controlled-intravenous analgesia (PCIA) of dexmedetomidine 0.05 μg/kg/h for 72 h after surgery, and the control group received conventional PCIA of sufentanil 3 μg/kg for 72 h. The primary outcome was a visual analog scale (VAS) on coughing 24 h after surgery. Secondary outcomes included the time to first analgesic request, pressing times of PCIA, time to first flatus, and hospital stay.Results: There was no difference in the cough-VAS at 24 h (median [interquartile range]) between the intervention group [3 (2– 4)] and control group [3 (2– 4), P = 0.36]. The median difference (95% CI) in the cough-VAS at 24 h was [0 (0 to 1), P = 0.36]. There was no significant difference in the time to first analgesic request, pressing times of PCIA, and hospital stay between groups (P > 0.05). A significant decrease in time to first flatus was observed in the intervention group (P < 0.01).Conclusion: Opioid-sparing analgesia provided safe and analogous postoperative analgesia with a shortened time to first flatus, compared with sufentanil-based analgesia in thoracoscopic surgery. This might be a novel method recommended for thoracoscopic surgery.Graphical Abstract: Keywords: opioid-sparing, intercostal nerve block, dexmedetomidine, sufentanil, opioid consumption, thoracoscopic surgery

Purpose: This study investigated whether the divided method of multi-level intercostal nerve block (ML-ICB) could reduce the ropivacaine dose required during thoracoscopic pulmonary resection, while maintaining the resting postoperative pain scores. Methods: This retrospective, single-cohort study enrolled 241 patients who underwent thoracoscopic pulmonary resection for malignant tumors between October 2020 and March 2022 at a cancer hospital in Japan. ML-ICB was performed by surgeons under direct vision. The differences in intraoperative anesthetic use and postoperative pain-related variables at the beginning and end of surgery between group A (single-shot ML-ICB; 0.75% ropivacaine, 20 mL at the end of the surgery) and group B (divided ML-ICB, performed at the beginning and end of surgery; 0.25% ropivacaine, 30 mL total) were assessed. The numerical rating scale (NRS) was used to evaluate pain 1 h and 24 h postoperatively. Results: Intraoperative remifentanil use was significantly lower in group B (14.4 ± 6.4 μg/kg/h) than in group A (16.7 ± 8.4 μg/kg/h) (P = 0.02). The proportion of patients with NRS scores of 0 to 3 at 24 h was significantly higher in group B (85.4%, 106/124) than in group A (73.5%, 86/117) (P = 0.02). The proportion of patients not requiring postoperative intravenous rescue drugs was significantly higher in group B (78.2%, 97/124) than in group A (61.5%, 72/117) (P < 0.01). Conclusion: The divided method of ML-ICB could reduce the intraoperative remifentanil dose, decrease the postoperative pain score at 24 h, and curtail postoperative intravenous rescue drug use, despite using half the total ropivacaine dose intraoperatively.

The efficacy of thoracoscopic intercostal nerve blocks (TINBs) for noxious stimulation from video-assisted thoracic surgery (VATS) remains unclear. The efficacy of TINBs may also be different between nonintubated VATS (NIVATS) and intubated VATS (IVATS). We aim to compare the efficacy of TINBs on analgesia and sedation for NIVATS and IVATs intraoperatively. Sixty patients randomized to the NIVATS or IVATS group (30 each) received target-controlled propofol and remifentanil infusions, with bispectral index (BIS) maintained at 40–60, and multilevel (T3–T8) TINBs before surgical manipulations. Intraoperative monitoring data, including pulse oximetry, mean arterial pressure (MAP), heart rate, BIS, density spectral arrays (DSAs), and propofol and remifentanil effect-site concentration (Ce) at different time points. A two way ANOVA with post hoc analysis was applied to analyze the differences and interactions of groups and time points. In both groups, DSA monitoring revealed burst suppression and α dropout immediately after the TINBs. The Ce of the propofol infusion had to be reduced within 5 min post-TINBs in both NIVATS (p < 0.001) and IVATS (p = 0.252) groups. The Ce of remifentanil infusion was significantly reduced after TINBs in both groups (p < 0.001), and was significantly lower in NIVATS (p < 0.001) without group interactions. The surgeon-performed intraoperative multilevel TINBs allow reduced anesthetic and analgesic requirement for VATS. With lower requirement of remifentanil infusion, NIVATS presents a significantly higher risk of hypotension after TINBs. DSA is beneficial for providing real-time data that facilitate the preemptive management, especially for NIVATS. [ABSTRACT FROM AUTHOR]

Aim: Pain palliation is the most critical content of the treatment in traumatic rib fractures. The study aimed was to investigate the effect of including intercostal nerve block in the treatment of rib fractures on pain control. Material and Method: Patients treated for traumatic rib fractures in the thoracic surgery clinic of our center between February 2022 and June 2022 were evaluated retrospectively. The characteristics of the patients, their visual analogue scale scores, analgesic medication needs, and hospital stay were recorded. The data of the patients who underwent intercostal nerve blockade and those who were treated with standard analgesic medications were compared. Results: A total of 49 patients were included in the study. A total of 18 (36.7%) patients underwent daily intercostal nerve block. Standard pain treatment was applied to 31 (63.3%) patients. In the group of patients who underwent intercostal nerve blockade, the mean pain score on the third day and the mean need for nonsteroidal anti-inflammatory medication were significantly lower. Conclusion: In our study, the adding an intercostal nerve block to the treatment of rib fractures provided better pain control and reduced the need for analgesic medication. [ABSTRACT FROM AUTHOR]

The primary objectives of the study were to analyse the robotic approach and ultrasound-guided paravertebral block compared to thoracoscopic intercostal nerve block after robotic pulmonary lobectomy on postoperative pain and opioids use. The secondary objectives were to analyse and compare patients' necessity of additional antalgic drugs and patients' performance during respiratory therapy, following robotic surgery and in the two groups. Consecutively, 52 patients undergoing robotic pulmonary lobectomies were treated either with ropivacaine-based intercostal nerve block or paravertebral block from February 2022 to October 2022. When necessary, morphine was administered at day 1. Acetaminophen was administered as an additional antalgic drug on demand up to 3 g per day. Pain was measured 1 h after the end of the surgical procedure and daily through the pain numeric rating scale (NRS). Morphine administration rate and per day and total additional administrations of acetaminophen were recorded. Pain and opioids administration was measured 1 month after the procedure. Data were analysed in the overall population and in the intercostal nerve block group VS paravertebral block group. Overall, 34.6% of the patients required morphine administration and 51.7% of the patients required at least daily acetaminophen administration up to discharge. At 1 month postoperatively, four patients presented with chronic pain and one still was under opioid medication. At intergroup analysis, the paravertebral block group demonstrated lower NRS at fixed time points (p < 0.0001) and lower morphine consumption (45.7%VS11.8%; p = 0.02). Acetaminophen rescue administration at fixed time points was lower in the paravertebral block group (p < 0.0001) and mobility and dynamic pain resulted in better results (p = 0.03; p = 0.04). At 1 month, no differences were found between study groups. Similarly to other minimally invasive techniques, postoperative pain may arise after robotic pulmonary lobectomy. Paravertebral bloc can help to reduce postoperative pain as well as morphine and antalgic drugs administration and improve early mobilization. [ABSTRACT FROM AUTHOR]

Abstract Background Preemptive intercostal nerve block (pre-ICNB) achieves the same analgesic effects as postoperative ICNB (post-ICNB) remains unclear. This study aimed to evaluate the efficacy of preemptive ICNB on perioperative outcomes for patients undergoing video-assisted thoracic surgery (VATS). Methods This was a randomized, open-label study (ChiCTR2200055667) from August 1, 2021, to December 30, 2021. Eligible patients scheduled for lobectomy for lung cancer were allocated into the pre-ICNB group and the post-ICNB group. The postoperative pain evaluation, patient rehabilitation, and opioid consumption were observed. Results A total of 81 patients were included. When compared with the post-ICNB group, the pre-ICNB group had a lower proportion of hypertension comorbidity (P = 0.023), significantly lower total consumption of morphine milligram equivalents (MMEs) (P = 0.016), shorter extubation time (P = 0.019). The pre-ICNB group has similar Numeric Rating Scales (NRS) scores of dynamic pain in the post-anesthesia care unit (PACU), postoperative 6 h, 12 h, 24 h, and 48 h (P > 0.05), and had simialr scores of Bruggrmann Comfort Scale (BCS) in postoperative 6 h, 12 h, 24 and 48 h (P > 0.05). The scores of the Mini-mental state examination (MMSE) and Ramsay in the pre-ICNB group were comparable to those in the post-ICNB group, except the scores of MMSE and Ramsay in postoperative 6 h were lower (P = 0.048 and P = 0.019). The pain evaluation in the 1-month follow-up was comparable with that in the post-ICBN group (P > 0.05). Conclusions Pre- ICNB is equally efficacious in perioperative pain management as post-ICNB, and pre-ICNB significantly reduces intra-operative opioid consumption, providing faster recovery in PACU.

Abstract Background Intercostal nerve block (ICNB) is a very effective analgesic method. We aimed to explore the effect of preemptive analgesia with ultrasound-guided intercostal nerve block on postoperative analgesia in thoracoscopic surgery. Methods 126 patients, aged 18–70 years, with American Society of Anesthesiologists (ASA) physical status I-II and scheduled for thoracoscopic pulmonary resection were enrolled in this study. 119 patients were left for final analysis. Patients were randomly allocated to group ICNB and group CONTROL. Patients in CONTROL group were administered sufentanil with patient-controlled analgesia device after operation In group ICNB, patients received ropivacaine ICNB prior to surgery and patient-controlled analgesia device after operation. The primary outcome is visual analog scale pain score (VAS) at rest at 0,4, 8,16,24,48,72 and 168 h postoperatively and they were compared. Surgical outcomes and rescue analgesia requirement were also recorded. Results VAS scores were statistically significantly lower for ICNB group compared to control group at 0, 4, 8, 16, 24 and 48 h postoperatively. The duration of insertion of chest tube in ICBN group was shorter than that in control group, and the difference was statistically significant (4.69 ± 2.14 vs. 5.67 ± 2.86, P = 0.036). The postoperative hospital stay, incidence of nausea and vomiting and postoperative pulmonary infection rate in ICBN group were all lower than those in the control group, but there were no statistical differences. The frequency of rescue analgesia during 48 postoperative hours was different between the two groups (ICNB vs. Control; 9.83% vs. 31.03%, P = 0.004). Conclusions For patients undergoing thoracoscopic surgery, ultrasound-guided ICNB is simple, safe, and effective for providing acute postoperative pain management during the early postoperative stage.

Objective: To investigate the effect of anterior serserus plane and intercostal nerve block under intravenous anesthesia combined with ultrasound guidance in thoracoscopic cuneform resection of lung. Methods: 60 patients with thoracoscopic wedge-shaped pulmonary resection admitted to our hospital from October 2021 to December 2022 were selected and divided into control group(30 cases)and observation group(30 cases) according to random number table method.30 patients in the control group received general anesthesia combined with thoracic paravertebral block+intercostal nerve block, and 30 patients in the observation group received general anesthesia combined with serratus anterior+intercostal nerve block. The mean arterial pressure and heart rate of the two groups were compared at the time of monitoring home invasion(T0), immediately after intubation(T1), at the time of operation sectioning(T2) and immediately after extubation(T3), the pain scores at resting and coughing at 2 h, 4 h, 12 h, 24 h and 48 h after surgery, and the stress response indexes at T0-T3 points were compared between the two groups. The intraoperative dose of vasoactive drugs was compared between the two groups, and the incidence of perioperative adverse reactions was compared between the two groups. Results: Compared with T0, the mean arterial pressure and heart rate at T1, T2 and T3 increased significantly(P＜0.05), while there was no difference between the two groups at T1(P＞0.05); the mean arterial pressure and heart rate in the observation group at T2 and T3 were significantly lower than those of the control group(P＜0.05). With the extension of postoperative time, the pain scores in resting and coughing state of the two groups were significantly decreased(P＜0.05), but there was no statistical significance between the two groups at the same time point(P＞0.05).Compared with T0 point, tumor necrosis factor, interleukin 6 and interleukin 10 levels in the observation group were significantly increased at T1, T2 and T3(P＜0.05), but there was no statistical significance between the observation group and control group at the same time point(P＞0.05). The dose of vasoactive drugs used in the observation group was significantly lower than that in the control group(P＜0.05). The incidence of adverse reactions in observation group was 16.77 % lower than that in control group(23.33 %), but there was no statistical significance between groups(P＞0.05). Conclusion: The hemodynamics of thoracoscopic wedge resection patients who underwent intravenous general anesthesia combined with ultrasound-guided anterior serration plane + intercostal nerve block were more stable, and the amount of vasoactive drugs required during the operation was significantly reduced.

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]

Uniportal video-assisted thoracic surgery (VATS) has been successfully used worldwide as a minimally invasive method of thoracoscopic surgery. Although pain was significantly reduced after VATS, acute postoperative pain was still significant. This study aimed to assess the advantages and feasibility of intercostal nerve block in uniportal VATS. We conducted a retrospective analysis of perioperative data from 280 consecutive patients who underwent uniportal VATS at our institution between May 2021 and February 2022. The patients were assigned to either Group A (142 patients with 3 intercostal nerves blocked) or Group B (138 patients with 5 intercostal nerves blocked). We analyzed the perioperative data of both groups and utilized repeated measures ANOVA to determine the difference in postoperative pain between the two groups across time. A total of 280 patients underwent successful uniportal VATS during the study period. There were no significant differences between Group A and Group B in terms of age, gender, pulmonary function, arterial blood gas analysis, laterality, incision location, nodule size, nodule location, operative time, blood loss, drainage time, length of hospital stays, tumor stage, or postoperative complications. Furthermore, no surgical or 30-day postoperative mortalities occurred. Using repeated measures ANOVA, we found that the intercostal nerve block had significant effects on the group, time, and interaction terms group × time (P < 0.05). Intercostal nerve block is safe and effective, and is associated with simple, accurate, and high patient satisfaction as opposed to other postoperative analgesics in uniportal VATS. Blocking five intercostal nerves may be more beneficial for effective postoperative pain management. Nevertheless, further confirmation through prospective randomized controlled trials is required.

Objectives: The efficacy of dexamethasone palmitate in extending durations of local anesthetic blocks is uncertain. In a randomized, double-blind study of patients undergoing video-assisted thoracoscopic surgery, we tested whether intravenous or perineural dexamethasone palmitate caused prolonged analgesia after intercostal nerve block. Methods: A total of 90 patients subjected to video-assisted thoracoscopic surgery between May and December 2022 were randomly assigned to one of three intercostal nerve blocks study arms (n = 30 each), requiring the addition of 0.5% ropivacaine (23 ml) as follows: controls (C group), 2 ml saline; IV-DXP group, 2 ml saline + 2 ml (8 mg) intravenous dexamethasone palmitate; and PN-DXP group, 2 ml (8 mg) perineural dexamethasone palmitate. Time to first postoperative remedial analgesia served as primary outcome measure. Secondary endpoints included postoperative opioid consumption, pain scores by Visual Analog Scale, analgesia satisfaction, and related adverse effects. Results: Compared with controls or the IV-DXP group, time to first postoperative remedial analgesia was longer and postoperative opioid consumption for rescue analgesia was lower in the PN-DXP group (p 0.05). Conclusions: Perineural dexamethasone palmitate is a promising adjunct to ropivacaine intercostal nerve block by prolonging analgesia with almost no related adverse effects.

The letter to the editor was written in response to "The effect of ultrasound-guided intercostal nerve block on postoperative analgesia in thoracoscopic surgery: a randomized, double-blinded, clinical trial", which was recently published by Li et al. (J Cardiothorac Surg 18(1):128, 2023). In this article, Li et al. showed that addition of a preoperative intercostal nerve block to the multimodal analgesic strategy significantly reduced the pain scores within 48 h after surgery. However, we noted several issues in this study that were not well addressed. They were no use of a standard opioid-sparing multimodal analgesic strategy recommended in the current Enhanced Recovery After Surgery protocols for thoracic surgery, the lack of clear description for reasonable selection of rescue analgesics, the interpretion of between-group differences in the postoperative pain scores based on only statistical differences rather than clinically meaningful differences, inclusion of patients who were not blinded to study intervention, not reporting cumulative opioid consumption and complications of intercostal nerve block. We believe that clarification of these issues is not only useful for improving design quality of randomized clinical trials which assess postoperative analgesic efficacy of nerve blocks, but also is helpful for the readers who want to use an opioid-sparing multimodal protocol including a nerve block in patients undergoing thoracoscopic surgery.

Abstract Background The objective of this study was to compare analgesic efficacy of erector spinae plane block(ESPB) and thoracic paravertebral block(TPVB) combined with intercostal nerve block(ICNB) after video assisted thoracoscopic surgery(VATS). Methods Patients were enrolled into three groups according to analgesia technique as ICNB, TPVB + ICNB or ESPB + ICNB: respectively Group C(n = 58), Group T (n = 56) and Group E (n = 59). Patients were followed up by a trained data investigator at 2, 6, 8, 12, 24, 48 h after surgery, and the visual analog scale(VAS) at rest and coughing were recorded. The moderate and severe pain mean VAS ≥ 4 when coughing. The postoperative opioids consumption, incidence of postoperative nausea and vomiting (PONV), supplementary analgesic requirements within 48 h, length of stay in PACU, ambulation time, postoperative days in hospital and potential side effects, such as hematoma, hypotension, bradycardia, hypersomnia, uroschesis, pruritus and apnea were recorded. Results The incidence of moderate-to-severe pain was no significant difference between 3 groups in 24 h and 48 h (P = 0.720). There was no significant difference among the 3 groups in the resting pain intensity at 2, 6, 8, 12, 24 and 48 h after surgery(P > 0.05). In 2-way analysis of variance, the VAS when coughing in Group T were lower than that in Group C (mean difference = 0.15, 95%CI, 0.02 to 0.29; p = 0.028). While no difference was found when comparing Group E with Group C or Group T(P > 0.05). There was no difference between the three groups in the sufentanil consumption( within 24 h p = 0.472, within 48 h p = 0.158) and supplementary analgesic requirements(p = 0.910). The incidence of PONV and the length of stay in PACU, ambulation time and postoperative days in hospital were comparable in the 3 groups(P > 0.05). Two patients from Group T developed hematoma at the site of puncture. Conclusions The present randomized trial showed that the analgesic effect of TPVB + ICNB was superior to that of INCB after VATS, the analgesic effect of ESPB was equivalent to that of TPVB and ICNB.

Abstract Background Adequate pain control after video-assisted thoracoscopic surgery (VATS) for lung resection is important to improve postoperative mobilisation, recovery, and to prevent pulmonary complications. So far, no consensus exists on optimal postoperative pain management after VATS anatomic lung resection. Thoracic epidural analgesia (TEA) is the reference standard for postoperative pain management following VATS. Although the analgesic effect of TEA is clear, it is associated with patient immobilisation, bladder dysfunction and hypotension which may result in delayed recovery and longer hospitalisation. These disadvantages of TEA initiated the development of unilateral regional techniques for pain management. The most frequently used techniques are continuous paravertebral block (PVB) and single-shot intercostal nerve block (ICNB). We hypothesize that using either PVB or ICNB is non-inferior to TEA regarding postoperative pain and superior regarding quality of recovery (QoR). Signifying faster postoperative mobilisation, reduced morbidity and shorter hospitalisation, these techniques may therefore reduce health care costs and improve patient satisfaction. Methods This multi-centre randomised study is a three-arm clinical trial comparing PVB, ICNB and TEA in a 1:1:1 ratio for pain (non-inferiority) and QoR (superiority) in 450 adult patients undergoing VATS anatomic lung resection. Patients will not be eligible for inclusion in case of contraindications for TEA, PVB or ICNB, chronic opioid use or if the lung surgeon estimates a high probability that the operation will be performed by thoracotomy. Primary outcomes: (1) the proportion of pain scores ≥ 4 as assessed by the numerical rating scale (NRS) measured during postoperative days (POD) 0–2; and (2) the QoR measured with the QoR-15 questionnaire on POD 1 and 2. Secondary outcome measures are cumulative use of opioids and analgesics, postoperative complications, hospitalisation, patient satisfaction and degree of mobility. Discussion The results of this trial will impact international guidelines with respect to perioperative care optimization after anatomic lung resection performed through VATS, and will determine the most cost-effective pain strategy and may reduce variability in postoperative pain management. Trial registration The trial is registered at the Netherlands Trial Register (NTR) on February 1st, 2021 (NL9243).

Pneumothorax is a rare but potentially serious iatrogenic complication of intercostal nerve block. This case report emphasizes the importance of imaging guidance and careful patient assessment to mitigate complications in high-risk individuals undergoing intercostal nerve block. An elderly male with chronic obstructive pulmonary disease and undergoing chemotherapy for mediastinal metastasis of small-cell liver carcinoma developed severe postherpetic neuralgia resistant to pharmacological therapy. An ultrasound-guided intercostal nerve block was performed which resulted in a pneumothorax, subsequently managed with an intercostal drain. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The aim of the study was to assess the efficacy of different peripheral nerve blocks, compared to conventional methods (analgesics and epidural block), for pain relief in rib fracture patients. MATERIALS AND METHODS: PubMed, Embase, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched. The review included studies that were either randomized controlled trials (RCTs) or observational in design with propensity matching. The primary outcome of interest was patient's reported pain scores, both at rest and on coughing/movement. The secondary outcomes were length of hospital stay, length of stay at intensive care unit (ICU), need for rescue analgesic, arterial blood gas values and parameters of lung function test. STATA was used for statistical analysis. RESULTS: The meta-analysis was conducted with 12 studies. Compared to conventional methods, peripheral nerve block was associated with better pain control at rest 12 hours (SMD -4.89, 95% CI: -5.91, -3.86) and 24 hours (SMD -2.58, 95% CI: -4.40, -0.76) after institution of block. At 24 hours after block, the pooled findings indicate better pain control on movement/coughing for the peripheral nerve block group (SMD -0.78, 95% CI: -1.48, -0.09). There were no significant differences in the patient's reported pain scores at rest and on movement/coughing at 24 hours post-block. There were no differences in the overall risk of any complications (RR 0.48, 95% CI: 0.20, 1.18), pulmonary complication (RR 0.71, 95% CI: 0.35, 1.41) and in-hospital mortality (RR 0.62, 95% CI: 0.20, 1.90) between the two groups. Peripheral nerve block was also associated with a relatively lower need for rescue analgesic (SMD -0.31, 95% CI: -0.54, -0.07). There were no differences in the length of ICU and hospital stay, risk of complications, arterial blood gas values or functional lung parameters, i.e., PaO2 and forced vital capacity between the two management strategies. CONCLUSIONS: Peripheral nerve blocks may be better than conventional pain management strategies for immediate pain control (within 24 hours of initiation of block) in patients with fractured ribs. This method also reduces the need for rescue analgesic. The skills and experience of the health personnel, facilities for care available and the cost involved should guide the decision on which management strategy to utilize. [ABSTRACT FROM AUTHOR]

Objectives: Our Enhanced Recovery After Thoracic Surgery protocol was implemented on February 1, 2018, and firmly established 7 months later. We instituted protocol modifications on January 1, 2020, aiming to further reduce postoperative opioid consumption. We sought to evaluate the influence of such efforts on clinical outcomes and the use of both schedule II and schedule IV opioids following robotic thoracoscopic procedures. Methods: A retrospective study of patients undergoing elective robotic procedures between September 1, 2018, and December 31, 2020, was conducted. Essential components of pain management in the original protocol included nonopioid analgesics, intercostal nerve blocks with long-acting liposomal bupivacaine diluted with normal saline, and opioids (ie, scheduled tramadol administration and as-needed schedule II narcotics). Protocol optimization included replacing saline diluent with 0.25% bupivacaine and switching tramadol to as needed, keeping other aspects unchanged. Demographic characteristics, type of robotic procedures, postoperative outcomes, and in-hospital and postdischarge opioids prescribed (ie, milligrams of morphine equivalent [MME]) were extracted from electronic medical records. Results: Three hundred twenty-four patients met the inclusion criteria (159 in the original and 183 in the optimized protocol). There was no difference in postoperative outcomes or acute postoperative pain; there was a significant reduction of in-hospital and postdischarge opioid requirements in the optimized cohort. For anatomic resections: mean, 60.0 MME (range, 0-60.0 MME) versus mean, 105.0 MME (range, 60.0-150.0 MME), and other procedures: mean, 0 MME (range, 0-60 MME) versus mean, 140.0 (range, 60.0-150.0 MME) (P

Background: ː Pain management is essential in postoperative settings, especially with pediatric patients. Donor site pain after rib cartilage harvest is severe, particularly during the early postoperative period. This study aimed to explore the effectiveness of ultrasound guided single-injection intercostal nerve block (ICNB) as a component of multimodal analgesia for pediatrics undergoing autologous auricular reconstruction. Methods: ː Fifty pediatric patients aged 6–16 years and scheduled for 2 rib cartilages harvest surgery were enrolled in this double-blind, prospective and randomized study. Pediatrics were randomly assigned into two groups: the intercostal nerve block group (group B) and the control group (group C). The nerve block was performed with 2 ml 0.25% ropivacaine each intercostal nerve in group B. Patients from group C received Tramadol 2 mg/kg by the end of the surgery as control. Tramadol-based patient-controlled intravenous analgesia and rescue analgesia were given in both groups. The primary outcome was pain scores at early postoperative period (VAS and FLACC scale, 4 h, and 8 h). The secondary outcome was the postoperative Tramadol consumption and time point of first rescue analgesic demand. Results: ː VAS score was significantly lower in group B than group C at 4 h and 8 h postoperatively [2.5(2–5) vs. 4(2.5–5.5), p = 0.041 at 4 h; 3(2.5–4.5) vs. 4(3–5), p = 0.047 at 8 h]. Total Tramadol consumption in group B decreased significantly in contrast with group C at 8 h (p

Introduction: Thoracic epidural block, paravertebral block, and intercostal nerve block have been confirmed to alleviate acute pain after video-assisted thoracoscopic surgery (VATS). In contrast, little is known about the effects of these methods on chronic post-surgical pain (CPSP). Aim: To investigate the effects of epidural block, paravertebral block, and intercostal nerve block on postoperative chronic pain in patients undergoing VATS. Material and methods: A total of 240 patients undergoing VATS were randomly divided into 4 groups: an epidural group, paravertebral group, intercostal group, and a control group. All patients were interviewed after 1, 3, 6, and 12 months to investigate the incidence and severity of CPSP. Results: The epidural group had lower incidence of chronic pain within 6 months and it was less severe within 3 months compared with the control group. The incidence and intensity of chronic pain within 3 months were lower in the intercostal group than in the control group. The incidence and intensity of pain within 1 month of surgery were lower in the paravertebral group than in the control group. Of the 122 patients who developed pain after 1 month, 93 (76.2%) reported chronic pain after 12 months, and only 9 (11.7%) had chronic pain after 12 months despite reporting no pain at 1 month. Conclusions: The prevalence of CPSP after VATS is high. Epidural block, paravertebral block, and intercostal nerve block can all reduce the incidence and severity of CPSP, with epidural block showing the best effect. In addition to acute pain, 1-month postoperative pain also exerts a warning effect on CPSP. [ABSTRACT FROM AUTHOR]

Objectives: Autologous costal cartilage is commonly used as a graft material in plastic surgery. However, after autologous costal cartilage removal, the pain at the surgical site is particularly strong. We conducted this controlled clinical study to verify the efficacy of methylene blue (MB) in intercostal nerve block after autologous costal cartilage removal and to provide a reference for the application of MB in postoperative analgesia after autologous costal cartilage removal. Methods: In this study, 90 adolescent patients with congenital microtia who underwent autologous rib cartilage graft for auricular reconstruction were randomly allocated to one of three groups (Group A: intercostal nerve block was performed with 0.75% ropivacaine; Group B: intercostal nerve block was performed with 1% MB; and Group C: intercostal nerve block was performed with 1% MB and 0.75% ropivacaine mixture). Two trained researchers observed and recorded the pain status of the children at 6 hours (T1), 24 hours (T2), 48 hours (T3), and 72 hours (T4) after surgery, respectively. Numerical rating pain scale (NRS) was used for scoring. And adverse reactions such as nausea, vomiting, and skin itching were recorded. Results: In this study, there was no statistical difference in age and gender of patients in Groups A, B, and C (P >0.05). In terms of NRS comparison, 6 hours after operation (T1), Group B > Group A > Group C (P< 0.05); 24 hours after operation (T2), Group B > Group A > Group C (P< 0.05); 48 hours after operation (T3), Group B > Group A > Group C (P< 0.05); 72 hours after operation (T4), Group A > Group B > Group C (P< 0.05). There were no statistically significant differences in postoperative nausea, vomiting, and skin itching among the three groups (P>0.05). Conclusion: The analgesic effect of IV self-controlled analgesia combined with ropivacaine is quick, but the maintenance time is short. The analgesic effect of IV self-controlled analgesia combined with MB is slow to onset but long to maintain. The analgesic effect of IV self-controlled analgesia combined with MB and ropivacaine mixture is quick and maintained for a long time. Therefore, in patients after removal of costal cartilage, we recommend the analgesic treatment method of IV self-controlled analgesia combined with MB and ropivacaine mixture.
