Background: Caudal epidural block combined with general anesthesia remains a popular choice of anesthesia for both supraumbilical and infraumbilical surgeries. More recently transversus abdominis plane block performed under ultrasound guidance is being described as an effective technique for postoperative analgesia for lower abdominal surgeries. The present study aims to compare the efficacy of ultrasound –guided TAP block and caudal epidural for paediatric infraumbilical surgeries. Aims and Objectives: To compare the duration and efficacy of postoperative pain relief between TAP block and caudal epidural block in children undergoing lower abdominal surgeries. Methods: Fifty children of age group 2-7 years undergoing lower abdominal surgeries were randomized to groups T and C. All patients were given general anesthesia as per standardized anesthesia protocol. Group T were given ultrasound guided TAP block with 0.5 ml.kg-1 of 0.2% Ropivacaine. Group C were given 1 ml.kg-1 of 0.2% ropivacaine as caudal block. All the children were assessed using FLACC scale. Their vitals, pain scores, duration of postoperative analgesia and requirement of supplemental analgesics were noted. Results: Rescue analgesic requirement was significantly less in Group T compared to Group C. Mean postoperative analgesia time was significantly more in Group T (342 mins) as compared to Group C (198 mins). Conclusion: Ultrasound guided TAP block provides better postoperative analgesia after loer abdominal surgeries in children.
