A Prospective, randomized comparative study between ultrasound‐guided posterior quadratus lumborum block and ultrasound‐guided ilioinguinal/iliohypogastric nerve block for pediatric inguinal herniotomy

Abstract

The posterior quadratus lumborum block with 0.25% bupivacaine 0.5 mL/kg provided better pain control than the ilioinguinal/iliohypogastric nerve block with 0.25% bupivacaine 0.2 mL/kg after open herniotomy in children. The ultrasound guidance technique for the posterior quadratus lumborum block is safe and as simple as the ultrasound-guided ilioinguinal/iliohypogastric nerve block for pediatric patients.
