Arms Assigned Interventions
No Intervention: control group
no injection of local anesthetic agents
Experimental: Local infiltration group Procedure: Local infiltration group
patients would have 0.5 ml/kg of 0.25% bupivacaine if age < 6 months or 1 ml/kg if age > 6 months around the wound by surgeon. The needle will be injected in subcutaneous tissue parallel to the wound.
Other Name: local anesthetic infiltration
Experimental: TAP block group Procedure: TAP block
Surgical TAP block (sTAP: Patients would have 0.5 ml/kg of 0.25% bupivacaine if age < 6 months or 1 ml/kg if age > 6 months
Other Name: surgical transversus abdominis plane block

Detailed Description:

Most children experience postoperative pain after major abdominal surgery. They may have ineffective ventilation, following atelectasis and pneumonia if receive inadequate pain management. There are several methods used for pain relief such as epidural block, intravenous analgesia with local infiltration, transversus abdominis plane (TAP) block by ultrasound guided and surgical TAP block. Therefore, the investigators would like to compare the effectiveness of postoperative pain control with TAP block. However, TAP block in children need experience and ultrasound. The investigators decided to do surgical TAP block performing by inject from peritoneum point to skin instead.
