| Background The transversus abdominis plane block (TAP) has been described for pain management following abdominal surgery in adults, but there are only few reports on its use in pediatrics. The aim of this study was to evaluate the analgesic effect of ultrasound guided TAP block in patients scheduled for open appendectomy versus an active comparator (wound infiltration). Methods Forty-four children aged 4–16 years (ASA 1–2) were enrolled. Patients were randomized into two groups (22 in each). Patients in group (T) were assigned to receive ultrasound guided TAP block using 0.4 ml/kg of bupivacaine 0.25%, and those in group (L) were assigned to receive local infiltration by the surgeon. Maximum pain scores, the time to the first analgesic requirement and the number of analgesic requirements were recorded over 48 h. Results The ultrasound guided TAP block increased the mean time to the first analgesic requirement (10.4 ± 1.5 h) in comparison with the local infiltration group (5.4 ± 1.5). The cumulative number of doses of analgesic was significantly lower in TAP group than in local infiltration group (3.7 ± 1.1 versus 5.3 ± 2.1) and the Pain Scale score was significantly lower in the TAP group over the study period. Besides, there were no complications attributable to the ultrasound guided TAP block. Conclusion Ultrasound-guided TAP block with (0.4 ml/kg) 0.25% bupivacaine provides prolonged postoperative analgesia and reduced analgesic use without any clinical side-effects after appendectomy in children. | ||||
