Outcomes of post burn flexion contracture release under tourniquet versus tumescent technique in children

Abstract

ObjectiveTo compare the clinical outcomes of release of flexion contractures after burn of the hand in children using tourniquet or tumescent technique in terms of operative time, postoperative pain score, and percentage of graft take. MethodsPatients aged 3 to 12 years who required release of post-burn flexion contractures involving volar aspect of palm and fingers were enrolled from outpatient clinic. Patients were randomized in 1:1 ratio to the use of either tumescent technique or tourniquet during contracture release. Duration of procedure, postoperative pain score, percentage of graft take, and any complications were assessed and analyzed in both groups by a blinded observer. ResultsOf the 160 patients randomized in the study (80 in each group), 84 (52.5%) were males. The mean±SD age of participants was 7.84±3.49 years, with no statistically significant difference in gender and age distribution between the groups. Similarly, there was no statistically significant difference in duration of surgery in both groups. However, there was a statistically significant difference in percentage of graft take at the 14th postoperative day; significantly more graft take was noted in the tumescent group (8.97±3.7cm vs. 7.26±2.6cm; P=0.001). Mean analgesia consumed in the tumescent group was significantly less than that of the tourniquet group (6.26±1.9mg vs. 9.41±2.2mg; P≤0.001). Similarly, statistically significant difference in the mean FLACC pain score was noted, with remarkably low pain score in the tumescent group. ConclusionWe found that the use of the tumescent technique for the release of flexion contracture resulted in better graft take, lower pain scores, and lesser consumption of analgesic than the use of tourniquet.
