Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Burns can be caused by heat, electricity, chemicals, friction, or radiation. Skin barrier damage can lead to infection, fluid loss, and electrolyte abnormalities. Long-term consequences include permanent scarring, loss of sensation, and in severe cases loss of extremities due to inadequate circulation. Burns are assessed by determining the percentage of body surface area (BSA) involved, the depth, and the area of the body involved. A common system used to estimate BSA is following the “rule of nines.” This system breaks up the body into zones that each equate to 9% of BSA (see figure). Some clinicians use the palm of the patient’s hand as an approximate equivalent to 1% BSA.
