Comparison of Outcome of Post Burn Flexion Contracture Release Under Tourniquet Verses Tumescent Technique in Children

Comparison of Outcome of Post Burn Flexion Contracture Release Under Tourniquet Verses Tumescent Technique in Children

Post burn flexion contractures are common in pediatric age group. Release of contracture and coverage with full thickness skin graft (FTSG) is a widely used procedure for this problem. This procedure is routinely done under tourniquet control because bloodless operative field is essential to visualize important neurovascular structures in hand.

Use of tumescent technique without a tourniquet is gaining acceptance because it avoids complications associated with tourniquet use, maintains a blood less surgical field and decreases operative time. Furthermore use of tumescent anesthesia often results in better surgical outcomes.

Although the benefits of tumescent technique used in wide awake hand surgery are well documented, epinephrine at a concentration of 1:1 000,00 has also been used as a replacement for pneumatic tourniquet for release of hand contracture in infants and adults under general anesthesia. Thus epinephrine 1:1,000,00 in saline solution can be a potential replacement for a tourniquet in hand surgeries done under general anesthesia.

To the investigators' knowledge no study has so far been done to compare the outcome of release of post burn flexion contractures under tumescent technique with general anesthesia or under tourniquet control with general anesthesia.
