Reducing rebound pain severity after arthroscopic shoulder surgery under general anesthesia and interscalene block: a two-centre randomized controlled trial of pre-emptive opioid treatment compared with placebo. Can J Anaesth 2024; 71:773-783. [PMID: 37833472 DOI: 10.1007/s12630-023-02594-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 05/03/2023] [Accepted: 05/09/2023] [Indexed: 10/15/2023] Open
Abstract
PURPOSE Although a single-injection interscalene block provides effective early postoperative analgesia following shoulder surgery, patients may experience "rebound pain" when the block resolves. Our objective was to determine if oral hydromorphone (2 mg) given six hours after a single-injection interscalene block for arthroscopic shoulder surgery leads to a clinically significant reduction in the severity of rebound pain. METHODS After approval from research ethics boards, we conducted a two-centre, parallel-group, double-blind, randomized, placebo-controlled superiority trial. Patients received preoperative interscalene block, general anesthesia, and either hydromorphone or placebo six hours after the block. The primary outcome was the worst pain score in the first 24 hr postoperatively, measured on an 11-point (0-10) numerical rating scale. RESULTS A total of 73 participants were randomly assigned to either the hydromorphone or placebo group. There was no statistically significant difference in the mean (standard deviation) worst pain score within 24 hr between the hydromorphone and placebo groups (6.5 [2.4] vs 5.9 [2.3]; mean difference, 0.6; 95% confidence interval, -0.5 to 1.8). Similarly, we did not find any significant difference in the pain trajectory, opioid use, or incidence of nausea and vomiting between the groups. The mean time to worst pain was 14.6 hr, and the mean time to first rescue analgesia was 11.3 hr after interscalene block. CONCLUSION Hydromorphone 2 mg given six hours after interscalene block did not reduce the severity of rebound pain postoperatively compared with placebo in patients undergoing arthroscopic shoulder surgery.

Abstract
OBJECTIVE Postoperative neurological symptoms (PONS) are recognized complications of regional anesthesia and orthopedic surgery. We aimed to better characterize prevalence and potential risk factors in a homogeneous population of randomized, controlled trial participants. METHODS Data were pooled from two randomized controlled trials of analgesia after interscalene block with perineural or intravenous adjuvants (NCT02426736, NCT03270033). Participants were at least 18 years of age and undergoing arthroscopic shoulder surgery at a single ambulatory surgical center. PONS were assessed by telephone follow-up at 14 days and 6 months postoperatively, and defined as patient report of numbness, weakness, or tingling in the surgical limb, alone or in combination, and regardless of severity or etiology. RESULTS At 14 days, PONS occurred in 83 of 477 patients (17.4%). Among these 83 patients, 10 (12.0%) continued to have symptoms a half-year after surgery. In exploratory univariate analyses, no patient, surgical or anesthetic characteristics were significantly associated with 14-day PONS except for lower postoperative day 1 Quality of Recovery-15 questionnaire total score (OR 0.97 (95% CI, 0.96 to 0.99), p<0.01). This result was driven largely by the emotional domain question scores (OR 0.90 95% CI 0.85 to 0.96, p<0.001). Report of all three of numbness, weakness and tingling at 14 days vs other 14-day symptom combinations was associated with persistent PONS at 6 months (OR 11.5 95% CI 2.2 to 61.8, p<0.01). CONCLUSION PONS are common after arthroscopic shoulder surgery performed with single injection ultrasound-guided interscalene blocks. No definitive mitigating risk factors were identified.

Abstract
The interscalene block (ISB) is the standard regional anesthesia for shoulder arthroscopy. However, the superior trunk block (STB) is an alternative with a potentially safer profile. This meta-analysis aimed to compare the incidence and degree of hemidiaphragmatic paralysis and block efficacy of these techniques. We searched MEDLINE, EMBASE, Scopus, and Cochrane databases to identify randomized controlled trials (RCTs). The main outcome was total hemidiaphragmatic paralysis. We used the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) framework to assess the certainty of evidence. Four RCTs and 359 patients were included. The STB group showed lower total hemidiaphragmatic paralysis (RR 0.07; 95% CI 0.04 to 0.14; p<0.0001). The incidence of subjective dyspnea (p = 0.002) and Horner's syndrome (p<0.001) was significantly lower with STB relative to ISB. There was no significant difference between groups in block duration (p = 0.67). There was a high certainty of evidence in the main outcome as per the GRADE framework. Our findings suggest that STB has a better safety profile than ISB, resulting in lower rates of hemidiaphragmatic paralysis and dyspnea while providing a similar block. Therefore, STB could be preferred to ISB, especially in patients susceptible to phrenic nerve paralysis complications.

Abstract
PURPOSE To compare early postoperative pain in patients undergoing hip arthroscopy with versus without the pericapsular nerve group (PENG) block. METHODS A retrospective chart review of prospectively collected data was performed to identify patients who underwent hip arthroscopy at a single institution between May 2019 and October 2021. Patients were included if they received general anesthesia and were opioid naive. Patients who received the PENG block were compared with patients who did not. Opioid, benzodiazepine, and antiemetic medication administration was recorded both intraoperatively and for the duration of the patient's stay in the postanesthesia care unit (PACU). Opioids administered were converted to morphine milligram equivalents (MMEs). Pain was assessed with a visual analog scale. Time to discharge (in minutes) and complications were recorded. RESULTS A total of 53 patients were identified for inclusion, of whom 28 received the PENG block and 25 did not. Opioid consumption was significantly lower in the PENG block group both intraoperatively (16.9 ± 14.1 MMEs vs 40.6 ± 18.3 MMEs, P < .001) and in the PACU (14.4 ± 11.4 MMEs vs 31.2 ± 20.1 MMEs, P < .001). The highest recorded PACU pain score was significantly greater in the no-PENG block group (7.0 ± 1.9 vs 5.3 ± 2.1, P = .004). Within the PENG block group, fewer patients required antiemetics (0 vs 4, P = .043). There was a greater time to discharge in the no-PENG block group (161 ± 50 minutes vs 129 ± 34 minutes, P = .008). No complications, including postoperative falls, were noted in either group. CONCLUSIONS The PENG block improves perioperative outcomes by decreasing pain, opioid consumption, time to discharge, antiemetic requirements, and benzodiazepine requirements after hip arthroscopy. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Abstract
Purpose Ultrasound-guided interscalene nerve block (UISB) is commonly used to alleviate postoperative pain during shoulder arthroscopy. This retrospective observational study aimed to evaluate the intraoperative advantages and analgesic effects of preoperative UISB. Patients and Methods In this retrospective observational study, a total of 170 patients underwent shoulder arthroscopy at a tertiary medical center in southern Taiwan throughout 2019. After applying the exclusion criteria, 142 of these cases were included, with 74 and 68 in the UISB group and control groups, respectively. The primary outcome was the evaluation of intraoperative morphine milligram equivalent (MME) consumption. Secondary outcomes were sevoflurane consumption, the use of intraoperative antihypertensive drugs, and postoperative visual analog scale (VAS) scores in the post-anesthesia care unit (PACU) and in the ward at 24 h after surgery. Results Preoperative UISB effectively reduced opioids and volatile gases during surgery, supported by a 48.1% and 14.8% reduction in the median intraoperative MME and sevoflurane concentrations, respectively, and showed less need for antihypertensive drugs. The preoperative UISB group also showed significantly better performance on the VAS in both the PACU and ward. Conclusion Taken together, the preoperative UISB reduced not only intraoperative MME and sevoflurane consumption but also had satisfactory VAS scores in both the PACU and ward without any symptomatic respiratory complications. In summary, preoperative UISB is a reliable adjuvant analgesic technique and a key factor in achieving opioid-sparing and sevoflurane-sparing anesthesia and multimodal analgesia during shoulder arthroscopy.

Abstract
BACKGROUND Despite the widespread use and sales of cannabidiol (CBD) products in the United States, there is a paucity of literature to evaluate its effectiveness, safety, or ideal route of administration for postoperative pain. PURPOSE To evaluate the potential analgesic effects of buccally absorbed CBD in patients who have undergone arthroscopic rotator cuff repair (ARCR). STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS This was a US Food and Drug Administration-sanctioned, multicenter, placebo-controlled, randomized, double-blinded trial conducted in patients undergoing ARCR. Patients aged from 18 to 75 years undergoing ARCR were prospectively enrolled and randomized to the control and experimental groups. The experimental group received an oral, buccally absorbed tablet containing 25 mg of CBD 3 times a day if <80 kg, or 50 mg of CBD 3 times a day if >80 kg, for 14 days postoperatively, while the control group received an identical placebo. Patients were followed up on days 1, 2, 7, and 14, and visual analog scale (VAS) for pain scores, opioid consumption, and satisfaction with pain control were recorded. Additionally, liver function tests were conducted on days 7 and 14 to assess safety, and nausea was monitored. P < .05 was considered to be statistically significant. RESULTS Overall, 100 patients were recruited, with 1 patient being excluded, for a total of 99 patients. There were no significant differences in patient demographics between the 2 groups. On day 1, the VAS pain score was significantly lower in the CBD group than in the control group (4.4 ± 3.1 vs 5.7 ± 3.2, respectively; P = .04), although this difference was no longer present on day 2 (4.7 ± 2.8 vs 5.3 ± 2.6, respectively; P = .32). On both days 1 and 2, patient satisfaction with pain control was significantly higher in the CBD group than in the control group (day 1: 7.0 ± 3.0 vs 5.6 ± 3.7, respectively [P = .04]; day 2: 7.3 ± 2.5 vs 6.0 ± 3.3, respectively [P = .03]). The quantity of opioids consumed was low in both groups, and there were no statistically significant differences in opioid consumption (P > .05). On days 7 and 14, there were no statistically significant differences in VAS scores, opioid consumption, or patient satisfaction with pain control between the CBD and control groups (P > .05 for all). There were no significant differences in liver function test results postoperatively (P > .05). CONCLUSION Buccally absorbed CBD demonstrated an acceptable safety profile and showed significant promise in the reduction of pain in the immediate perioperative period after ARCR compared with the control. Further studies are currently ongoing to confirm dosing and effectiveness in other orthopaedic conditions. REGISTRATION NCT04672252 (ClinicalTrials.gov identifier).

Abstract
INTRODUCTION The efficacy of pregabalin for pain management of shoulder arthroscopy remains controversial. We conduct this meta-analysis to explore the influence of pregabalin versus placebo on the postoperative pain intensity of shoulder arthroscopy. METHODS We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through November 2019 for randomized controlled trials assessing the effect of pregabalin versus placebo on pain control of shoulder arthroscopy. This meta-analysis was performed using the random-effect model. RESULTS Three randomized controlled trials were included in the meta-analysis. Overall, compared with control group for shoulder arthroscopy, pregabalin remarkably decreased pain scores at 0 to 1 hour (Std. MD = -0.57; 95% CI = -1.04 to -0.09; P = .02) and 12 hours (Std. MD = -0.37; 95% CI = -0.72 to -0.02; P = .04), as well as analgesic consumption (Std. MD = -1.84; 95% CI = -2.24 to -1.44; P < .00001), but showed no notable influence on pain scores at 24 hours (Std. MD = -0.54; 95% CI = -1.47 to 0.38; P = .25), nausea or vomiting (RR = 0.84; 95% CI = 0.53-1.33; P = .45), dizziness (RR = 1.14; 95% CI = 0.89-1.47; P = .30). CONCLUSIONS Pregabalin may benefit to pain control after shoulder arthroscopy.
