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

Brief Summary:

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.

Current Primary Outcome:

  • Operative time to secure graft [ Time Frame: Time of surgery ]

    Operative time to secure graft will be measured by calculating the time taken to secure per square centimeter of graft.

    Time (T) in minutes to secure per cm2 of graft = Total operative time / size of graft secured in cm2 measured by transparent graft paper In tourniquet group total operative time will be measured as total time taken from start of applying tourniquet including time taken for exsanguinations to the time till completion of dressing.

    In tumescent group total operative time will be measured as total time taken from start of injecting the tumescent solution including waiting time for tumescent solution to produce maximum vasoconstriction (25 minutes) to the time till completion of dressing

  • Percentage graft taken [ Time Frame: 14th day post surgery ]
    It will be measured by the percentage of graft take at 14th post-operative day. Percentage graft take = Graft secured at the time of operation measured by using transparent graph paper / graft take at 14th post-operative day measured by using transparent graph paper.
  • Post-operative pain (FLACC scale) [ Time Frame: At First hour after arrival in ward following surgery ]
    Post-operative pain will be measured by blinded on duty doctor using Face Leg Activity Cry Consolability (FLACC) scale. Postoperative pain will be measured by using FLACC pain scale by blinded observer at first hour postoperatively taking time of arrival in the ward as zero hour

  • Original Primary Outcome: Same as current

    Current Secondary Outcome:
