According to the Rule of 9's, how much of the body surface area does the head of a child account for?

The Rule of 9's is a method used to calculate the total body surface area (TBSA) affected by burns in adults and children. In children, body proportions differ from those of adults, which is why the percentages for various regions can be different. According to this rule, the head of a child is assigned a value of 18% of the total body surface area.

This higher percentage compared to adults (where the head accounts for 9%) reflects the greater proportion of the head relative to their body size. Understanding this distinction is crucial for effective assessment and treatment of burn injuries in pediatric patients, as accurate estimations of TBSA are essential for fluid resuscitation and determining the severity of burns. In this context, recognizing the correct percentage specifically for children is vital for ensuring appropriate medical intervention.
