1.17 ESTIMATION OF BODY SURFACE AREA

               The body surface area is the measured or calculated surface of a human body. The body surface area is used in many measurements in medicine, including the calculation of drug dosages and the amount of fluids to be administered intravenously. The body surface area

 

can be calculated by various formulas without direct measurement. When weight and height are known, the formula of DuBois and DuBois (1) published in 1916 is recommended.

               (1) The body surface area (m2 ) = Height (cm)0.725 × Weight (kg)0.425 × 71.84 × 10–4

               The table of the body surface area from weight and height, which is calculated from the formula of DuBois and DuBois, is represented in the following pages.

               A simplified formula, which can be calculated for the body surface area, is commonly known as the Mosteller formula (2) published in 1987.

               (2) The body surface area (m2 ) = [Weight (kg) × Height (cm)/3600]1/2
