"Xenograft" dressing in the treatment of burns

Biologic dressings (xenografts and allografts) are an integral part of modern burns care. They provide; reduction of pain and adherence without need for additional fixation; antibacterial action that is a function of its adherence; protection against physical trauma; appropriate heat and moisture retention. Allografts are more effective but supply may be severely restricted. Porcine skin is our standard dressing for partial-thickness burns; it also has a role in providing temporary coverage of full-thickness defects and for debriding burns/ulcers.
