Comparison of erector spinae plane block versus quadratus lumborum block for post-caesarean analgesia: Systematic review, meta-analysis, and trial sequential analysis.

ABSTRACT:

Background and aims

Post-caesarean pain significantly impacts maternal recovery. The erector spinae plane (ESP) and quadratus lumborum block (QLB) are regional analgesic techniques used for postoperative pain management; however, their comparative effectiveness remains uncertain. The objective was to compare the efficacy of ESP and QLB regarding post-caesarean pain intensity, opioid consumption, time to first analgesic request, and the incidence of nausea and vomiting.

Methods

A systematic review and meta-analysis of randomised controlled trials comparing ESP and QLB in women undergoing caesarean section was conducted according to PRISMA guidelines (PROSPERO ID: CRD42024612438). The electronic databases PubMed, Embase, Cochrane Library, and Scopus were searched. Effect sizes
