Measure
Treatment Group
Transversus Abdominis Plane Block: A high frequency (5-10 mHz) ultrasound probe (Sonosite Micromaxx, Licence No 12407) will be placed on the flank at the midpoint between the iliac crest and lower costal margin. The three muscle layers of external oblique, internal oblique, and transversus abdominis will be visualized. A 22G short-bevel block needle will be advanced in an anterior-to-posterior direction, in-plane with the probe, until the tip is visualized in the transversus abdominis plane. After negative aspiration, 0.4 ml/kg of bupivacaine 0.25% with 1:200,000 epinephrine will be injected. The total dose of bupivacaine will not exceed 2 mg/kg and the total volume will not be more than 20 ml.
Control Group
Standard: Circumferential subcutaneous infiltration of the ostomy wound with bupivacaine 0.25% with 1:200 000 epinephrine 0.4 ml/kg by the surgeon after skin closure.
