Quadratus lumborum block versus transversus abdominis plane block for inguinal hernia repair: A systematic review and meta-analysis with trial sequential analysis.

Introduction: Postoperative pain management is crucial for patient recovery with Quadratus Lumborum Block (QLB) and Transversus Abdominis Plane Block (TAPB) emerging as potential techniques. We aimed to compare the analgesic efficacy of QLB and TAPB in patients undergoing inguinal hernia repair.

Methods: We performed a systematic review of Cochrane, EMBASE, and MEDLINE databases to identify randomized controlled trials comparing QLB and TAPB in patients undergoing inguinal hernia repair.
