Dubois D, Dubois EF. There were many formulas developed in the past years for calculating the Body Surface Area. October 317:1098. The Mosteller formula is considered to be the most common body surface area equation today. Various Body Surface Area formulas have been developed over the years, originally by Dr.s Du Bois & Du Bois, followed by Gehan and George, Haycock, Boyd and Mosteller. We retrospectively compared body surface area (BSA) using the Mosteller formula square root(H x (w/360)) and a simple weight-based BSA formula ([4Wkg+7]/ [90+Wkg]). Nomogram Method . The participants were 363 children who underwent cardiac surgery from 1991 to 2000. For example, some medications ordered for a pediatric patient may be based on body surface area (BSA) and strong medications such as chemo agents (anticancer medications). Body surface area is used to help calculate the most accurate medication dosage for a patient. Simplified Calculation of Body Surface Area. This is the Mosteller formula, although it is not the best for infants and children but it the easiest to remember and execute at the bedside. 1916; 17:863-871. Used Formula (Mosteller): Cato Software Solutions does not take any responsibility about … The New England Journal of Medicine published it in the year 1987. A formula to estimate the approximate surface area if height and weight be known. Pediatric Dosage Calculations Pediatric Dosage Calculations Most drugs in children are dosed according to body weight (mg/kg) or body surface area (BSA) (mg/m2). Pediatric dosage explained. Arch Intern Med. The Nomogram method is utilized to determine the correct pediatric medication dosage based specifically on the patient's size. Estimating Percent Total Body Surface Area in Children Affected by Burns (A) Rule of "nines" (B) Lund-Browder diagram for estimating extent of burns (Adapted from The Treatment of Burns, edition 2, Artz CP and Moncrief JA, Philadelphia, WB Saunders Company, 1969) Author: changf It is probably not worth the trouble to debate about which formula may or may not be slightly better. Body Surface Area: DISCLAIMER: All calculations must be confirmed before use. CATO - Quality Management for Oncology Therapy. Care must be taken to properly convert body weig ht from pounds to kilograms (1 kg= 2.2 lb) before calculating doses based on body weight. BSA is a measurement used in many medical tasks. Body surface area in square meters = the square root of " Wt(in Kg) x Ht(in meter) ÷ 3600" Mosteller RD. It is also used in some cases to determine fluid requirements administered intravenously. This review will discuss how to solve nursing dosage and calculation body surface area problems. These formulas all give slightly different results. The authors make no claims of the accuracy of the information contained herein; and these suggested doses are not a substitute for clinical judgement. New Eng J Med. There are several methods available for estimating pediatric dosages, the most commonly used being dosing according to body weight or body surface area (BSA).. Doses are often expressed as mg/kg/day (similar to mg/kg) or mg/kg/dose and accompanied by a frequency of administration that can vary from once daily to every hour.
