A comparative study of preoperative ultrasound-guided lumbar erector spine plane block and preoperative ultrasound-guided caudal block for postoperative pain control in pediatric lower limb surgeries: A randomized controlled trial

Abstract

Background Erector spinae plane block (ESPB) is a relatively new type of regional anesthesia that has demonstrated efficacy in pain management. The study uses ultrasound (US) guidance to perform the ESPB and evaluates its efficacy and safety compared to the traditional caudal block (CB) in managing postoperative pain in children undergoing lower limb surgeries.
