Abstract

OBJECTIVE: Estimation of the surface area involved is vital to evaluation and treatment of burns. Common teaching suggests the palm approximates 1% of the total body surface area (TBSA). However, early century literature suggests the palmar surface of the entire hand approximates 1% of the TBSA. We sought to determine whether the palm or the entire palmar surface of the hand approximates 1% TBSA in children. DESIGN: A prospective, convenience sample. MATERIALS AND METHODS: Using height, weight, and standard nomograms, body surface area was determined. A photocopy of the hand was used to determine the surface area of the palm and the entire palmar surface of the hand. RESULTS: In 91 children, the mean percent of the TBSA represented by the entire palmar surface was 0.94% (95% confidence interval (C.I.) 0.93-0.97), and the mean percent of the TBSA represented by the palm was 0.52% (95% C.I. 0.51-0.53). CONCLUSION: The entire palmar surface of a child's hand more closely approximates 1% TBSA, while the palm approximate 0.5% TBSA.
