ultrasound guided transversus abdominis plane block versus local wound infiltration for post-operative analgesia in children undergoing appendectomy: A Randomized Controlled Trial

Appendectomy is one of the most frequently performed surgical procedures in children and is associated with significant postoperative discomfort and pain.Multimodal approaches to the provision of postoperative analgesia often incorporate blockade of the abdominal wall, such as ilioinguinal blockade or wound infiltration. However, the efficacy of these approaches is unclear. This study is a prospective,randomized comparison of 2 patient groups. One group of patients will receive an ultrasound guided transversus abdominis plane (TAP) block using 0.4 ml/kg of bupivacaine 0.25% with 1:200 000 epinephrine The total dose of bupivacaine will not exceed 2 mg/kg and the total volume will not be more than 20 ml. . The second group will receive local anesthetic infiltration by the surgeon at the end of surgery for a laparoscopic appendectomy.
