Outcome Measures
Primary Outcomes (1)
Morphine Requirement
The primary endpoint will be the proportion of children in each group requiring two or more (≥ 2) boluses of morphine in the PACU.
within the first 48 hours after surgery
Study Arms (2)
Treatment group
EXPERIMENTALBupivacine-TAP block
Control Group
ACTIVE COMPARATORBupivacaine- wound infiltration
Interventions
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.
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.

- children in whom a TAP block is contraindicated, i.e. surgical scar or distorted anatomy at the site of injection
- postoperative admission to the intensive care unit
- children with a known allergy to bupivacaine
- children with a history of chronic abdominal pain
- use of opioid analgesics prior to surgery
