In the pediatric Rule of Nines, what percentage of TBSA does the head account for?

In the pediatric Rule of Nines, the head accounts for 18% of the total body surface area (TBSA). This is a key aspect of the pediatric assessment for burn victims since children have a proportionally larger head compared to adults. The Rule of Nines is a quick method for estimating the extent of burns across different age groups, and in children, the head's surface area is notably higher in relation to the rest of the body.

For infants and young children, the body surface area proportions differ significantly from adults. In adults, the head accounts for about 9% of the total body surface area. Understanding these differences is crucial for properly assessing burn injuries and determining the appropriate treatment and fluid resuscitation needs. This specific percentage reflects the anatomical variances in infants and children and is an essential factor in pediatric emergency care.
