The British National Formulary (BNF),1 Martindale’s Pharmacopoea2 and many other reference textbooks state that the most reliable methods for calculation of children’s drug doses are those based on body surface area (BSA). Doses may be calculated by bodyweight or body surface area.

Ancel Keys, a physiology professor, used Quetelet's equation as part of a 1972 published report on obesity and created the name body mass index or BMI. Authoritative and practical information on the selection and clinical use of medicines. British Journal of Anaesthesia 1997; 78: 601­605 COMMENTARIES Calculation of drug dosage and body surface area of children J. These links are aimed at physicians and pharmacists. 59th edn. Body Surface Area. Body surface area in squared meters and squared feet in the graph and tables is calculated using our body surface area calculator. Calculate body surface area given the height and weight. BNF Publications. For body surface area calculations in paediatrics, see BNF for Children. Dubois D, Dubois EF. Example. While widely used in population health studies, the BMI equation has been critiqued for its use in individual diagnoses for determining whether someone is overweight or obese. Input Weight: kg : lbs : Input Height: cm: in : Body surface area (m 2) = The calculation is from the formula of DuBois and DuBois: BSA = (W 0.425 x H 0.725) x 0.007184. where the weight is in kilograms and the height is in centimeters. This principle has been com- … 1916; 17:863-871. A man measuring 165 cm and weighing 63 kgs, according to boyd's formula will have body surface area of = 0.0003207 x 165 0.3 x 63000 (0.7285 - (0.0188 x log(63000)) BSA = 1.7164 m 2 Arch Intern Med. A formula to estimate the approximate surface area if height and weight be known. A. LACK AND M. E. STUART-TAYLOR A large number of children's drug dosage rules have been described,3­5 almost all using percentages of an adult dose to calculate an appropriate child's dose--the notable exception being the commonly used "n" mg kg91 … Body surface area (BSA), as the name suggests, is the calculated or estimated surface area of a person’s body.

BNF- 59 (2010) British National Formulary. Arch Intern Med. Dubois D, Dubois EF. TBSA burns You can quickly estimate the total body surface area of a burn by using the "rule of nines" in adults.In babies and young children, different percentages are used because the ratio of the combined surface area of the head and neck to the surface area of the limbs is typically larger in children than that of an adult(See table below).
