The aim of this study is to evaluate the preoperative and postoperative effects of caudal analgesia in pediatric orthopedic lower extremity surgery. A total of 92 children who underwent lower extremity osteotomy under general anesthesia were included in the study retrospectively. For caudal analgesia, 0.5 ml/kg 0.25% levobupivacaine and 20 mcg/kg morphine were used routinely. The effect of caudal analgesia on hemodynamic parameters (heart rate, mean arterial pressure, oxygen saturation, sevoflurane concentration) and procedural success rates were evaluated using objective pain scale scores (OPS). The mean age of the patients was 5.6±3.7 (1-13) years, and 54.3% of them were male. The mean operation time was 100±94 minutes. Side effects (nausea -vomiting) were detected in 12% of the cases. Caudal block suppressed the response to the surgical incision, and caused a decrease in heart rate, mean arterial pressure, and sevoflurane values (p <0.05). The OPS's were found to be = 5 in 8.7% of the patients, and in these patients' caudal block was considered to be unsuccessful for achieving a satisfactory analgesic effect. The time to the first analgesic administration to the patients was 526 ± 242 (85-1110) minutes after caudal analgesia. In the first 24 hours, 40.2% of the patients did not need additional analgesics. Caudal block is an anesthesia technique with high success rate, easy application, and low complication rate. In addition, it can provide long-term analgesia both perioperatively and postoperatively in pediatric patients undergoing subumblical surgery with a single injection technique. [ABSTRACT FROM AUTHOR]
