Calculating Body Surface Area Bsa And Determining Drug Dosage Based On Bsa

Calculating Body Surface Area Bsa And Determining Drug Body surface area (bsa) based dosing is a useful way to mitigate patient size variation in medication regimens. using bsa may help prescriber's dose more optimally to improve drug efficacy, minimize drug toxicity, and account for some changes in pharmacokinetics depending on patient factors. dubois formula for bsa dosing. This review will demonstrate step by step how to calculate the following: body surface area of a patient based on weight and height (both kilograms, centimeters, pounds, and inches will be reviewed) calculating the child’s dose based on the child’s bsa and the normal adult dose. calculating the amount of medication you will administer based.

Ppt Body Surface Area And Advanced Pediatric Calculations Powerpoint In example one, the question says, calculate the body surface area for a patient who weighs 70 kg and is 167.6 cm tall. based on the height, which is in centimetres and the weight which is in kilograms, the most appropriate form of the equation to use would be bsa in meters squared, being equal to the square root of the patient's height in centimetres, times the patient's weight in kilograms. It is calculated by multiplying the person's height in cm with his her weight in kilograms and dividing the value by 3600. then take the square root of the resulting value to get the bsa as stated below: bsa = [ (w x h) 3600] 0.5. a simpler version of this formula is stated below: bsa = 0.016667 × w0.5 × h0.5. Body surface area (bsa) based dosing is a useful way to mitigate patient size variation in medication regimens. using bsa may help prescriber's dose more optimally to improve drug efficacy, minimize drug toxicity, and account for some changes in pharmacokinetics depending on patient factors. The first step is to calculate the bsa of a subject from his her weight and height using one of the formulas listed in table 14.1. in the old days, use of biexponential formulas was cumbersome. graphic representation of those formulas, known as nomograms , was created for easy reading of bsa values (fig. 14.2).
