Samerchua A, Leurcharusmee P, Panichpichate K, et al. - Researchers compared ultrasound‐guided posterior quadratus lumborum block vs ilioinguinal/iliohypogastric nerve block in terms of postoperative analgesic effects in pediatric inguinal herniotomy in this randomized assessor‐blinded study. Random assignment of children (one‐ to seven‐year‐old) scheduled for unilateral open herniotomy was done to receive either ultrasound‐guided posterior quadratus lumborum block with 0.25% bupivacaine 0.5 mL/kg or ultrasound‐guided ilioinguinal/iliohypogastric nerve block with 0.25% bupivacaine 0.2 mL/kg following general anesthesia induction. The proportion of patients who took postoperative oral acetaminophen was the primary outcome. Better pain control was achieved with posterior quadratus lumborum block with 0.25% bupivacaine 0.5 mL/kg vs ilioinguinal/iliohypogastric nerve block with 0.25% bupivacaine 0.2 mL/kg following open herniotomy in children. Findings revealed the safety of the ultrasound guidance technique for the posterior quadratus lumborum block, and this technique was found to be as simple as the ultrasound‐guided ilioinguinal/iliohypogastric nerve block for pediatric patients.
