Question
How to calculate the burn area of a child?
Answer
The calculation of a child’s burn area is slightly modified based on the adult formula. The calculation for an adult’s body surface area is as follows: the head, face, and neck each account for 3%, totaling 9%; the anterior and posterior trunk each accounts for 13%, plus the perineum’s 1%, totaling 27%; the hands account for 5%, the forearms 6%, and the upper arms 7%, totaling 18%; the buttocks 5%, the thighs 21%, the lower legs 13%, and the feet 7%, totaling 46%.
