How do you calculate body surface area?
How do you calculate body surface area?
The most commonly used formula now is that of Mosteller, published in 1987 in The New England Journal of Medicine. According to Mosteller’s “simplified calculation of body-surface area In metric terms” the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.
How do you find the surface area of chemotherapy?
These measurements are used to calculate body surface area using the Du Bois method3 (BSA (m2) = Wt (kg) 0.425 x Ht (cm) 0.725 x 0.007184). If a patient started more than one chemotherapy regimen during the reporting period, only their first regimen with a valid height and weight recorded was included.
How does DuBois calculate body surface area?
A formula to estimate the approximate surface area if height and weight be known….meters inches.
| Body Surface Area | |
|---|---|
| Formula : | BSA (m2) = |
| Mosteller : | = √ height (cm) x weight (kg) 3600 |
| DuBois & DuBois : | = 0.20247 x height (m)0.725 x weight (kg)0.425 |
| Haycock : | = 0.024265 x height (cm)0.3964 x weight (kg)0.5378 |
Why is body surface area used?
Values for body surface area (BSA) are commonly used in medicine, particularly to calculate doses of chemotherapeutic agents and index cardiac output. Various BSA formulas have been developed over the years.
Why do we use body surface area for chemotherapy?
Dosing based on body surface area (BSA) is generally used in an effort to normalize drug concentrations. This is because it is well recognized that measures of many physiologic parameters that are responsible for drug disposition, including renal function and energy expenditure, can be normalized by use of BSA.
How do you calculate body surface area for a burn?
The Wallace Rule of Nines is a clinically efficient and accurate method to calculate the total body surface area of a burn. It is calculated by dividing the body into percentages of 9….What is the Wallace Rule-of-Nines?
| Rule-of-9s | Total | Subdivision |
|---|---|---|
| Back | 18% | – |
| Each Arm | 9% | Anterior Arm = 4.5% Posterior Arm = 4.5% |
What is normal BSA range?
The average adult BSA is 1.7 m2 (1.9 m2 for adult males and 1.6 m2 for adult females). This number is used to calculate dosages for cytotoxic anticancer agents.
