Burns are classified according to the depth of injury. A first-degree burn presents with pain and redness; only the epidermis is involved. Sunburns and blisters are examples of first-degree burns. A second-degree burn presents with pain, redness, and blistering; the epidermis and the superficial layer of the dermis are involved. Depending on the extent of the burn, excision of the burned skin layers and grafting may be needed to promote proper healing of the injury. With a third-degree burn, the epidermis and dermis are damaged. Third-degree burns may require excision down to fascia and routinely involve skin grafting, which may be sagged with allograft placement performed initially. A fourth-degree burn extends to bone, muscle, and tendon (National Burn Repository, 2010).
