Kropparealet

Kropparealet, also known as the body surface area (BSA), is a measure of the total surface area of the human body. It is an important parameter in various medical and scientific fields, including pharmacology, physiology, and nutrition. The BSA is used to calculate drug dosages, assess fluid requirements, and evaluate nutritional status.

The most commonly used formula to calculate BSA is the Mosteller formula, which is based on the weight (W) in kilograms and the height (H) in centimeters:

BSA (m2) = √(W × H) / 60

Another widely used formula is the Du Bois and Du Bois formula, which is based on the weight (W) in kilograms and the height (H) in meters:

BSA (m2) = 0.007184 × W^0.425 × H^0.725

Both formulas have their advantages and limitations, and the choice of formula may depend on the specific application and population being studied.

BSA is an essential tool for healthcare professionals, researchers, and clinicians, as it helps to standardize measurements and ensure accurate treatment plans. It is particularly useful in pediatrics, where the BSA can vary significantly among children of different ages and sizes. Additionally, BSA is used in the assessment of burn injuries, where the extent of the burn is often expressed as a percentage of the total body surface area.
