AbstractTransdermal buprenorphine (TBUP) may have some advantages for the management of acute postoperative pain. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of TBUP compared to other analgesics or placebo for acute postoperative pain. A systematic search was conducted using Embase, MEDLINE, and Cochrane Central Register of Controlled Trials (CENTRAL) until December 26, 2022. The search included randomized controlled trials comparing TBUP versus other analgesics or placebo for acute postoperative pain. A certainty assessment was conducted using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. The protocol for this review was registered on Prospective Register of Systematic Reviews (CRD42022318601). In total, 15 studies involving 1,205 participants were included that compared TBUP versus fentanyl (n = 2), celecoxib (n = 3), placebo (n = 2), tramadol (n = 5), diclofenac (n = 3), parecoxib (n = 1), and flurbiprofen (n = 1). Meta-analyses were conducted for 3 comparators that involved 2 studies each. There was no significant difference in pain between TBUP 10 mcg/h versus fentanyl 25 mcg/h (standardized mean difference [SMD] -.03, 95% confidence interval [CI] -.86 to .81, P = .95, I2 = 85%). TBUP 10 mcg/h was associated with less pain compared to celecoxib 200 mg twice daily (SMD -.32, 95% CI -.58 to -.05, P = .02, I2 = 0%) and placebo (SMD -2.29, 95% CI -4.32 to -.27, P = .03, I2 = 94%). The GRADE assessment showed a very low certainty of evidence for all comparisons. There is insufficient evidence that TBUP improves pain control compared to other analgesics for acute postoperative pain. PERSPECTIVE: This systematic review and meta-analysis compared the use of TBUP to other analgesics for postoperative pain. The results showed that there is insufficient evidence to recommend the use of TBUP in this setting. The findings will help clinicians select the most appropriate opioid regimens for postoperative pain.Copyright © 2023 United States Association for the Study of Pain, Inc. Published by Elsevier Inc.
