What is the surface area percentage of the back for an infant/toddler?

The surface area percentage of the back for an infant or toddler is commonly assessed as 18%. This value is essential for understanding fluid resuscitation and burn management in pediatric patients, as infants and toddlers have different body proportions compared to adults. The "Lund and Browder chart," a tool used for estimating body surface area in children, reflects that infants and toddlers have a larger head-to-body ratio, resulting in a unique distribution of surface area.

In practice, knowing that the back constitutes 18% of the total body surface area for this age group is critical during emergency situations when immediate calculations for fluid needs or burn coverage are necessary. This percentage helps healthcare providers make informed decisions about treatment plans tailored to the specific anatomical features of younger patients.
