biologic dressing,

a dressing for burn injuries that is made from pigskin or synthetic materials with characteristics like those of human skin. The dressing is most effective in treating burns that are of uniform depth and of superficial partial thickness. It should be applied as soon as possible after the injury and should adhere to the wound during healing. Once adherence is established the wound can be left open and the patient can bathe and wear clothing over it.
