In the baby/small child Rule of Nines, what percentage is allocated to the perineum?

• A. 6%
• B. 1%
• C. 10%
• D. 13%

Answer: (A)

In infants, the Rule of Nines is adjusted to match how their bodies are proportioned. The diaper region around the perineum represents a larger surface area relative to body size in babies than in adults, so it’s given a bigger share on the pediatric chart. That’s why the perineal area is allocated about 6% of total body surface area in the baby chart. This helps clinicians estimate burn size more accurately in young children. The other values are closer to adult proportions or would over- or underestimate the real pediatric surface area for that region.
