Final answer:
Due to the large third-degree burn of the skin, a skin graft is typically required. These burns destroy the skin's full thickness and underlying sensory functions. In severe cases, excision or amputation followed by grafting is necessary.
Step-by-step explanation:
Due to the large third-degree burn of the skin, a skin graft was indicated. Third-degree burns penetrate and destroy the full thickness of the skin, including both the epidermis and dermis, which can impair nerve endings and sensory function. Treatment of such burns often requires medical interventions such as excision (debridement) or in severe cases, amputation, followed by the grafting of skin from an unaffected area of the body or from skin grown in tissue culture.
A fourth-degree burn is even more severe than a third-degree burn, as it reaches underlying muscles and bones, leading to possible damage of nerve endings. In these cases, the rule of nines can be used to estimate the extent of the burn in relation to the body's total surface area, which is crucial for appropriate treatment planning. Special medical attention is critical to manage the dehydration, electrolyte imbalance, risk of infection, and to support tissue repair in patients with severe burns.
