How are burns classified and know how to use the rule of nines and how to measure burns.
One quick way to estimate the surface area that has been burned is to compare it to the size of the patient’s palm, including their fingers, which is roughly equal to 1% of the patient’s TBSA. This technique is called the rule of palm. Another useful measurement system is the rule of nines, which divides the body into sections, each of which is approximately 9% of TBSA (FIGURE 27-19). Remember that the head of an infant or child is relatively larger than the head of an adult, and the legs are relatively smaller. When you calculate the extent of burn injury, include only partial-thickness (second-degree) and full-thickness (third-degree) burns. Document superficial (first-degree) burns, but do not include them in the body surface area estimation of extent of burn injury.
___burns involve only the top layer of skin, the epidermis. The skin turns red but does not blister or burn through this top layer. The burn site is often painful. Sunburn is a good example of a superficial burn.
Superficial (first-degree)
____burns involve the epidermis and some portion of the dermis. These burns do not destroy the entire thickness of the skin, nor is the subcutaneous tissue injured. Typically, the skin is moist, mottled, and white to red. Blisters are present. Partial-thickness burns cause intense pain.
• Partial-thickness (second-degree)
___burns extend through all skin layers and may involve subcutaneous layers, muscle, bone, or internal organs. The burned area is dry and leathery and may appear white, dark brown, or even charred. Some full-thickness burns feel hard to the touch. Clotted blood vessels or subcutaneous tissue may be visible under the burned skin. If the nerve endings have been destroyed, a severely burned area may not have feeling and the surrounding less severely burned areas may be extremely painful.
• Full-thickness (third-degree)
