Comparison of Caudal Block and Sacral Erector Spina Block for Postoperative Analgesia following Pediatric Circumcision: A Double-Blind, Randomized Controlled Trial.

Introduction: Caudal block (CB) and erector spina plane block (ESPB) have been shown to provide effective postoperative analgesia following circumcision. Our aim was to compare the analgesic efficacy of sacral ESPB and CB, as well as the time to first analgesic requirement and postoperative complications.

Methods: Patients aged 1-7 years in the ASA I-II group, who were scheduled for circumcision, were included in the study. Blocks were performed under general anesthesia before the operation. Postoperative pain was evaluated using the Face, Legs, Activity, Cry, and Consolability (FLACC) scores. Analgesic requirements in the first 24 h postsurgery, the time of first analgesia requirement, and postoperative complications were recorded.

Results: A total number of 150 patients were included in the study. In the CB group, urinary retention was observed. No side effects were observed in the sacral ESPB group. The 4th and 6th h postoperative FLACC scores were lower in the ESP group. The number of analgesic consumption in the first 24 h postsurgery was significantly lower in the ESPB group (p < 0.001).

Conclusion: Based on our results, sacral ESPB performed with ultrasonography is a simple and safe regional anesthesia method that can be used to provide effective postoperative analgesia for circumcision.
