What percentage of body surface area is allocated for the head in the pediatric rule of nines?

In the pediatric rule of nines, the percentage of body surface area allocated for the head is 18%. This is an important guideline used in estimating the total body surface area affected by burns in children. The reasoning behind this allocation reflects the proportionally larger size of a child's head compared to that of an adult when considering overall body surface area. For children up to the age of about 16, the head is given a greater weight in surface area assessments, which assists in better management and treatment of burns.

In contrast, for adults, the head accounts for a smaller percentage of body surface area (approximately 9%). The pediatric rule of nines helps healthcare providers quickly calculate fluid resuscitation needs and the severity of burns in pediatric patients, making it an essential tool in emergency medical care for children.
