Abstract

Background: This study aimed to compare the effects of rectal midazolam addition after applying bupivacaine and caudal anesthesia on postoperative analgesia time, the need for additional analgesics, postoperative recovery, and sedation and to find out its adverse effects in children having lower abdominal surgery.

Methods: 40 children between 2 and 10 years of ASA I-II were randomized, and they received caudal anesthesia under general anesthesia. Patients underwent the application of caudal block in addition to saline and 1 mL/kg bupivacaine 0.25%. In the postoperative period, Group C (n = 20) was given 5 mL saline, and Group M (n = 20) was given 0.30 mg/kg rectal midazolam diluted with 5 mL saline. Sedation scale and postoperative pain scale (CHIPPS) of the patients were evaluated. The patients were observed for their analgesic need, first analgesic time, and adverse effects for 24 hours.

Results: Demographic and hemodynamic data of the two groups did not differ. Postoperative sedation scores in both groups were significantly lower compared with the preoperative period. There was no significant difference between the groups in terms of sedation and sufficient analgesia.

Conclusions: We conclude that caudal anesthesia provided sufficient analgesia in peroperative and postoperative periods, and rectal midazolam addition did not create any differences. This trial is registered with ClinicalTrials.gov NCT02127489.
