The clinical application on composite graft of acellular allo-dermal matrix and auto-microskin on escharectomy after deep burns / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To present the clinical application of composite graft of acellular allo-dermis matrix (ADM) with thin auto-microskin on burn wound.</p><p><b>METHODS</b>8 inpatients with 18 full thickness skin burn wounds were transplanted with allo-ADM after eschar was excised, then the auto-microskin and allo-human skin were covered on the area of the matrix, the wound where no allo-ADM grafting were covered as control groups only with auto-microskin and allo-human skin. The area of donor to wound is 15 - 18.</p><p><b>RESULTS</b>Survived rate of 18 pieces composite skin that allo-ADM with auto-microskin were grafted were 94%. After following up for 3 to 13 months, the skins of complex grifting had well elastic and smooth texture compared to auto-microskin grafted, they appeared less cicatrisation and ulceration. 3 months after operation, it was indicated by histological examination that tightknit the epithelial-dermal conjunction and epidermal papilla structure could be identified in the allo-ADM skin and there were orderly collagenous fibres, but scar skin structure was observed in that auto-microskin grifted area.</p><p><b>CONCLUSION</b>The graft effectiveness of allo-ADM and auto-microskin was better than that of auto-microskin, and this method could be used on major deep burn wound healing.</p>
