Background: Literature on the efficacy and safety of erector spinae plane block (ESPB) in pediatric patients is limited. Hence, we aimed to compare ESPB versus caudal epidural block (CEB) in children undergoing abdominal surgery. Methods: In this patient and assessor-blind study, fifty-two ASA I-II patients, between 1 to 9 years of age, were randomized into groups of 26 each. ESPB group received unilateral or bilateral ultrasound (USG)-guided ESPB with 0.5 ml/kg of 0.25% bupivacaine per side. CEB group received USG-guided CEB with 1 ml/kg of 0.25% bupivacaine. The primary objective was to estimate the proportion of patients requiring postoperative rescue analgesia. The secondary objectives were to assess postoperative Face, Legs, Activity, Cry and Consolability (FLACC) scale scores, duration of analgesia, and consumption of rescue analgesic drugs. Results: More patients in the ESPB group (88.4%), compared to the CEB group (42.3%), required rescue analgesics (P value |
