What is the total body surface area percentage for both arms in a child?

In pediatric assessment, the percentage of total body surface area (TBSA) attributed to both arms combined is established as 16%. This is based on the "Rule of Nines," which provides a quick method for estimating the TBSA affected by burns or injuries in both children and adults, albeit with slightly different values for pediatric patients. For children, each arm represents 9% of the TBSA; thus, when calculating for both arms together, it totals 18%. However, accounting for the proportion of the child's overall body surface area makes the combined percentage for both arms approximately 16%.

This distinction is critical for emergency care providers when evaluating burn severity and determining fluid resuscitation needs. Understanding the differences in surface area percentages between adults and children is essential for accurate assessment and treatment planning.
