Randomized Controlled Trial Clinical Trial
Comparison of caudal ketamine with or without bupivacaine in pediatric subumbilical surgery.
In this prospective, randomized, double-blind study, we evaluated the perioperative analgesic efficacy of caudal ketamine with or without bupivacaine in 62 American Society of Anesthesiologists I-II children undergoing lower abdominal surgery. Patients were randomized into three groups, and all blocks were placed under general anesthesia. Group 1 (n=20) had caudal injection of plain 0.125% bupivacaine 1 mlkg(-1). ⋯ Patients in group 3 had the longest duration of analgesia compared to the other two groups. There was no significant difference in the incidence of side effects among the three groups. We conclude that ketamine can safely be used as an adjuvant to prolong the duration of caudal analgesia in this group of West African children.
