Question
How to calculate the burn area of a child?
Answer
The Chinese nine-segment method: This involves dividing the human body into 11 equal parts, with each part equal to 9% of the body surface area. The head and neck account for one nine, or 9%. If the head and neck are burned, the burn area should be 9%. Within the head and neck, they can be further divided into the scalp, face, and neck, each accounting for 3%. If only the face is burned, the estimated burn area would be 3%. The calculation of a child’s body surface area differs slightly from that of an adult, as children have relatively larger heads and smaller limbs. Therefore, children of different ages can be calculated using the following formula.
