What is the percentage of body surface area represented by the head of a child?

The correct percentage of body surface area represented by the head of a child is indeed 12%. This is based on the "Lund and Browder chart," which is commonly used in pediatric burn assessments and is widely accepted in medical practice.

In children, the proportion of body surface area allocated to the head is greater compared to adults due to their smaller body size and larger head circumference relative to their body. Understanding this percentage is crucial for accurately assessing burn injuries and administering appropriate treatment, including fluid resuscitation for burns.

The values for adults are different, where the head represents about 9% of total body surface area. In pediatric care, knowing that the head contributes to 12% allows for a better understanding of the child’s anatomy, ensuring that calculations for medical interventions are precise and effective.
