Abstract
Background: Caudal epidural block (CEB) has long been used as a standard method for pain control in pediatric surgery. Erector spinae plane block (ESPB) is a newer technique that has attracted attention for its potential to provide analgesia in children. Aim: The aim of this study was to compare and evaluate the effectiveness of ESPB and caudal block on postoperative pain in pediatric patients who underwent unilateral inguinal hernia surgery. Methods: This prospective, randomized trial was conducted with a total of 60 pediatric patients, aged 1–8 years, in the ASA I–II group. The patients were randomly divided into two groups as Group CEB (n = 30), and Group ESPB (n = 30). In the caudal block group, 0.25% bupivacaine 0.5 ml/kg (max 20 ml) was administered in the caudal space, while in the ESPB block group, the block was performed with 0.5 ml/kg 0.25% (max 20 ml) bupivacaine at the L1 vertebral level. Face, legs, activity, cry, and consolability (FLACC) scores were recorded postoperatively at 1, 2, 4, 6, 12, and 24th hours. The first analgesic requirements and time for rescue analgesia were also recorded. Results: While no significant difference was noticed between the two groups’ FLACC scores at the zeroth hour, first hour, second hour, fourth hour, and sixth hour (i.e. postoperatively [P > 0.05]), the FLACC scores of 12th hour in the ESPB group were significantly lower than the caudal block group (P < 0.05). There was also no significant difference in intraoperative additional analgesia requirements between the groups (P > 0.05). The time to first postoperative analgesia in the ESPB group was higher than that in the caudal block group (P < 0.05). Conclusion: The ESPB provided superior postoperative analgesia to the CEB in pediatric patients undergoing inguinal hernia surgery, and ESPB can be used as a relatively safer postoperative multimodal analgesia approach as an alternative to CEB.
