In pediatric burn assessments, what percentage of the body volume do the arms account for?

In pediatric burn assessments, the percentage of body surface area attributed to the arms is typically structured within the framework of the "Lund and Browder chart," which is a tool used to estimate the total body surface area affected by burns in children. According to this chart, the arms together account for an estimated 9% of total body surface area.

Specifically, each arm is assigned approximately 4.5% of the total body surface area when considering burns. This total may be adjusted based on the child's age and body proportions, but generally for pediatric assessments, the combined percentage assigned to both arms is recognized as 9%. This systematic approach enables healthcare professionals to accurately assess burn severity and fluid resuscitation needs in pediatric patients.

This understanding is crucial because accurate burn assessment impacts treatment plans and outcomes for young patients. The other options do not reflect the commonly accepted values for pediatric burn assessments, as the figures they present do not align with established guidelines in the relevant medical literature.
