Comparison of Postoperative Analgesic Efficacy Between Ultrasonography-Guided Quadratus Lumborum and Transversus Abdominis Plane Blocks in Infants Undergoing Inguinal Hernia Surgery: Randomized Controlled Trial

Objective: We compared the analgesic efficacy of ultrasonography (USG)-guided quadratus lumborum (QL) and transversus abdominis plane (TAP) blocks in infants undergoing elective unilateral inguinal hernia surgery (IHS). Material Methods: This single-center, randomized, single-blind, 2-arm clinical trial included 60 IHS (aged 1 month to year) with ASA I'II. The patients were randomized into QL block (Group A) TAP B) groups. For both groups, 0.3 mL/kg 0.25% bupivacaine was injected under USG guidance. Age, sex, weight, anesthesia duration (min), recovery (min) recorded. heart rate (HR) recorded at baseline, after induction, 15 30 min blocks. Postoperatively, evaluated based on their Face, Legs, Activity, Cry, Consolability (FLACC) scores 0, 1, 2, 6, 12, 24 h. also first duration, requirement, rescue complications. primary outcome study FLACC score. Results: Sixty completed protocol. There no significant differences between groups terms age, or score HR h postoperatively. requirement time, not significantly different (p>0.05 for all comparisons). Conclusions: showed similar IHS.
