Treatment for a third-degree burn will depend on the severity of the burn. Burn severity is determined by:. A large third-degree burn heals slowly. After the burn heals, surgery may be needed. This is done to improve the ability to move, and to remove and repair scarred skin. In some cases, skin grafting may be needed to close or cover the burn. A skin graft is a piece of healthy skin from one part of the body that is removed and put on an area that needs skin. The area where a piece of skin is taken is called the donor site.
After a skin graft, the donor site looks like a scrape. After a skin graft:. A dressing is left on the graft site for a few days before it's changed. The site needs to be still and protected to start to heal. Be careful using car seats, strollers, and seatbelts that are left in hot cars. There are a variety of skin grafts, some that provide temporary cover and others that are for permanent wound coverage. Allograft, cadaver skin or homograft is human cadaver skin donated for medical use.
Cadaver skin is used as a temporary covering for excised cleaned wound surfaces before autograft permanent placement. Cadaver skin is put over the excised wound and stapled in place. After surgery, the cadaver skin may be covered with a dressing.
This temporary covering is removed before permanent autografting. Xenograft or heterograft is skin taken from a variety of animals, usually a pig. Heterograft skin became popular because of the limited availability and high expense of human skin tissue. Wound coverage using heterograft is a temporary covering used until autograft. Autograft is skin taken from the person burned, which is used to cover wounds permanently. Because the skin is a major organ in the body, an autograft is essentially an organ transplant.
Autograft is surgically removed using a dermatome a tool with a sharp razor blade. Only the top layer of skin is used for donor skin. The site the skin is taken from will heal on its own.
There are two types of autografts used for permanent wound coverage:. A surgeon will begin the operation by removing skin from the donor site. Once skin is removed from the donor site, the surgeon will carefully place it over the transplant area and secure it with a surgical dressing, staples, or stitches.
This also allows fluid to drain from under the skin graft. Fluid collection under the graft may cause it to fail. The doctor also covers the donor area with a dressing that will cover the wound without sticking to it.
The hospital staff will watch you closely after your surgery, monitoring your vital signs and giving you medications to manage the pain. The graft should start developing blood vessels and connecting to the skin around it within 36 hours. This may also happen if you smoke or have poor blood flow to the area being grafted. When you leave the hospital, your doctor will give you a prescription for painkillers to help minimize the pain.
The donor site will heal within one to two weeks, but the graft site will take a bit longer to heal. Second- and third-degree burns can cause scars.
