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

EXPERIMENTAL

Bupivacine-TAP block

Procedure: Transversus Abdominis Plane Block

Control Group

ACTIVE COMPARATOR

Bupivacaine- wound infiltration

Procedure: Standard

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.

Treatment group
StandardPROCEDURE

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.

Control Group

Eligibility Criteria

Age3 Months - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • children undergoing revision or closure of ostomy
  • American Society of Anesthesiologists Classification 1-3.

You may not qualify if:

  • children undergoing an additional surgical procedure (e.g. circumcision) at an anatomical location not covered by a one-sided/ unilateral TAP block, during the same anesthetic
  • 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
  • pregnancy
  • impaired renal function
  • impaired hepatic function
  • known impaired cardiac function
  • hypersensitivity to sodium metabisulfite
