Isaksson developed a simple formula for estimating the body surface area of a patient from height and weight. This formula is simple and requires only simple arithmetic. The author is from Sahlgren's Hospital in Gothenburg, Sweden.
Parameters:
(1) height in centimeters
(2) weight in kilograms
estimated body surface area in square meters =
= 1 + (((weight in kilograms) + ((height in cm) - 160)) / 100)
This can rearranged to:
estimated body surface area in square meters =
= (0.010 * ((height in cm) + (weight in kilograms))) - 0.60
Limitations:
• The formula is inaccurate for subjects with a body surface area < 0.8 square meters. This would correspond to infants and young children.
• The formula may underestimate body surface area for subjects with body surface areas > 2.2 square meters. This is about -5%, but the error is less than for that of DuBois and DuBois.
