Allograft Skin Applications in Burn Care
Summary
Allograft skin grafting remains an indispensable intervention in the management of severe burns, providing temporary wound coverage that mitigates fluid loss, reduces pain and lowers the risk of infection while definitive autografts are prepared. Cadaveric skin allografts retain an intact epidermal barrier and dermal matrix, facilitating early revascularisation and granulation tissue formation. Preservation methods such as cryopreservation and glycerol-based protocols extend tissue viability and simplify storage and distribution within dedicated skin banks. Despite advances in biosynthetic substitutes, human skin allografts continue to set the standard for biological dressings owing to their structural and immunological properties. The principal limitation is immunogenic rejection, which restricts their permanence and necessitates supplementary immunomodulatory strategies or sequential autografting. Globally, standards for donor screening, processing, disinfection and quality assurance have evolved to ensure microbiological safety and reproducible clinical outcomes, underscoring the critical role of well-regulated skin banking programmes in burn centres.
