Experience and efficacy of surgery for retaining viable subcutaneous tissue in extensive full-thickness burns.

BACKGROUND AND AIM

For adult patients with extensive full-thickness burns (EFTB), a fascial excision is mostly used but it causes a very significant deformity. This study aims to summarize experience and efficacy of surgery for retaining viable subcutaneous tissue in EFTB.

METHOD

Clinical data were reviewed for 31 consecutive adult patients with full-thickness burn (FTB) over 70% total body surface area (TBSA) and undergoing first tangential excision and skin grafting on subcutaneous tissue wound (TESGSTW) within 7 days post burn at our burn center between 2002 and 2013.

RESULTS

Average age, total burn area, and FTB area of 31 patients were 32.4 ± 12.8 years, 89.0 ± 6.2% and 80.4 ± 7.6% TBSA, respectively. Of these, 80.6% combined with inhalation injury and 71.0% supervened early shock. Eighteen patients who survived (58.1%) totally underwent 121 times of surgery, of which TESGSTW and autologous skin grafting were 41 and 88 times, respectively. Their average time and area of first tangential excision was 4.1 ± 0.6 days post burn and 33.8 ± 7.6% TBSA, respectively, and accumulated tangential excision area was 58.4 ± 10.8% TBSA. In 39 times of TESGSTW within 14 days post burn, cryopreserved alloskin or fresh young pigskin was applied on 84.6%, and average time and take rate of autologous skin grafting instead of grafted alloskin or xenoskin was 14.6 ± 0.7 days and 89.5 ± 1.4%, respectively. Scalp was the main donor site for autologous skin, especially microskin grafting. Systemic wound healing time roughly was 67.3 ± 1.9 days post burn, meanwhile, viable subcutaneous tissue was retained. Healed wounds were plump, and their extensibility and sensitivity were better by follow-up.

CONCLUSION

The surgical treatment in EFTB is practicable and effective.
