10) Skin graft, allograft
Humans can sustain intense burns and need skin grafts to cover the wound. While they are waiting for the autograft from the recipients skin to use as treatment they can use an allograft. An allograft is tissue that is removed from one individual and used on a different individual (ÒSkin BankingÓ). They normally use skin from cadaveric donors for the allograft. The doctor, coroner, or autopsy personnel removes the skin off of the cadaver and freezes it in cryoprotectants for up to 5 years until someone needs the skin (ÒSkin BankingÓ). They can also take the skin and immediately place it on the recipient after it has been released from quarantine which can last up to 10 days. The surgeons stitch it on the recipient as a protective barrier from infection and fluid loss, and promote underlying tissue to heal, but it will be rejected within 7-21 days (ÒSkin BankingÓ). That is why it is just a temporary fix until the autograft is available to be sewn on.
