Randomized trial evaluates erector spinae plane block for opioid reduction in bariatric surgery, suggesting effective pain management.

This review aims to evaluate the effectiveness of the erector spinae plane block in reducing opioid consumption during and after bariatric surgery.
Systematic review of randomized controlled trials searching MEDLINE, Embase, Scopus, and CENTRAL electronic databases.
Data from 9 trials involving 613 patients were analyzed, assessing risk of bias and quality of evidence.
Primary outcome measured was opioid consumption in the 24 hours post-operation.
ESP block reduced 24-hour opioid consumption by a mean of 36.94 mg (95% CI -60.85 to -13.03, p = 0.009).
Time to first request for analgesia was significantly prolonged in the ESP block group.
Intraoperative opioid requirements and postoperative pain scores were reduced in patients receiving the ESP block.

Chan et al. (2026) studied this question.
