Background:
The optimal method for postoperative analgesia after arthroscopic rotator cuff repair (ARCR) is still unclear.
Purpose:
To compare the efficacy of postoperative analgesic methods after ARCR through network meta-analysis of randomized controlled trials and prospective controlled trials.
Study Design:
Systematic review; Level of evidence, 2.
Methods:
Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched PubMed, Embase, and Web of Science from inception until April 12, 2022, for randomized controlled trials and prospective controlled trials evaluating neuraxial analgesia, peripheral nerve block, periarticular local anesthetic infiltration, intravenous patient-controlled analgesia, oral analgesia, or any combination of these methods for pain management after ARCR. Outcomes included pain scores at rest, morphine consumption, and complications (nausea and vomiting). Study quality was assessed using the Cochrane risk-of-bias tool. Network meta-analysis was used to assess the relative efficacy of the methods for postoperative analgesia. The best choice for postoperative analgesia was defined as the one with significant differences in pain scores and morphine consumption compared with placebo, with no significant difference in complications, during the initial 48 hours postoperatively.
Results:
Included were 42 studies with 3110 patients. Only suprascapular nerve block (SSNB) was significantly superior to placebo in pain scores (mean difference [MD], -0.93 [95% CI, -1.31 to -0.54] at 6 hours; MD, -2.34 [95% CI, -3.49 to -1.19] at 12 hours) and morphine consumption (MD, -17.70 [95% CI, -32.98 to -2.42] at 24 hours) (P < .05 for all), with no difference in complications (odds ratio, 0.96 [95% CI, 0.21 to 4.32]; P > .05). Pain scores were significantly lower with interscalene nerve block compared with SSNB (MD, -0.69 [95% CI, -1.17 to -0.20] at 6 hours; MD, -1.44 [95% CI, -2.21 to -0.67] at 12 hours) and with SSNB + axillary nerve block compared with SSNB (MD, -3.09 [95% CI, -4.18 to -1.99] at 6 hours; MD, -0.87 [95% CI, -1.71 to -0.03] at 12 hours) (P < .05 for all).
Conclusion:
Based on the current evidence, most analgesic methods lowered pain and morphine consumption compared with placebo. There were significant differences in pain scores between interscalene nerve block and SSNB during the first 12 hours postoperatively, and adding axillary nerve block to SSNB enhanced the analgesic effect.
