Their age ranged from 5 … Body Surface Area: DISCLAIMER: All calculations must be confirmed before use. A formula to estimate the approximate surface area if height and weight be known. This review will discuss how to solve nursing dosage and calculation body surface area problems. The participants were 363 children who underwent cardiac surgery from 1991 to 2000. 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. These formulas all give slightly different results. Used Formula (Mosteller): Cato Software Solutions does not take any responsibility about … 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. 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). Nomogram Method . 1916; 17:863-871. 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. New Eng J Med. October 317:1098. The Mosteller formula is considered to be the most common body surface area equation today. 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. The Nomogram method is utilized to determine the correct pediatric medication dosage based specifically on the patient's size. It is also used in some cases to determine fluid requirements administered intravenously. 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). Arch Intern Med. 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 Body surface area is used to help calculate the most accurate medication dosage for a patient. The New England Journal of Medicine published it in the year 1987. Body surface area in square meters = the square root of " Wt(in Kg) x Ht(in meter) ÷ 3600" Mosteller RD. BSA is a measurement used in many medical tasks. It is probably not worth the trouble to debate about which formula may or may not be slightly better. The authors make no claims of the accuracy of the information contained herein; and these suggested doses are not a substitute for clinical judgement. There were many formulas developed in the past years for calculating the Body Surface Area. 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]). Pediatric dosage explained.
