What is the surface area of a child?
What is the surface area of a child?
Average body surface area for children (9 years): 1.07 m2. Average body surface area for children (10 years): 1.14 m2. Average body surface area for children (12-13 years): 1.33 m2.
What is normal range for BSA?
1.7 m2
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.
How do I calculate my baby’s BSA?
The formula by Meban (BSA cm2 = 6.4954 × weight (g) 0.562 × crown-heel length (cm) 0.320) is possibly the best to estimate the body surface of newborns, followed by the Mosteller (√[(height in cm × weight in kg)/3600]) formula; however, the Boyd and Dubois formulas are not recommended for surface estimation of newborns …
How is body surface area measured?
The body surface area (BSA) of any adult, when derived from the arithmetic mean of the different values calculated from four independent accepted formulae, can be expressed accurately in Systeme International d’Unites (SI) units by the simple equation BSA = 1/6(WH)0.5, where W is body weight in kg, H is body height in …
Do babies have more surface area than adults?
Babies have a surface area to volume ratio three times that of adults and in toddlers the ratio is twice that of adults. Also, children tend to have more skin exposed and more cuts, abrasions and rashes than adults; this could easily lead to increased dermal absorption as a proportion of body weight.
Why do infants have a higher body surface area?
The body contains 2 major fluid compartments: the intracellular fluid (ICF) and the extracellular fluid (ECF). Infants’ and children’s higher body water content, along with their higher metabolic rates and increased body surface area to mass index, contribute to their higher turnover of fluids and solute.
How do you work out m2 of a child?
“A formula to estimate the approximate surface area if height and weight be known”. Archives of Internal Medicine 17 (6): 863-71….Table of average BSAs.
| ft2 | m2 | |
|---|---|---|
| Newborn child | 2.69 | 0.25 |
| Two-year-old child | 5.38 | 0.5 |
| Ten-year-old child | 12.27 | 1.14 |
| Adult female | 17.22 | 1.6 |
Is body surface area the same as BMI?
While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV.
Why do babies have more surface area?
At what age is a child’s liver fully developed?
Full maturity takes up to two years after birth to be achieved, and involves the normal expression of signalling pathways such as that responsible for the JAG1 genes (aberrations occur in Alagille’s syndrome), amino acid transport and insulin growth factors.
What is the average surface area of a human body?
Average Body Surface Area Values Adult Men 1.9 m 2 Adult Women 1.6 m 2 Child (12-13 years) 1.33 m 2 Child (10 years) 1.14 m 2
How do you calculate BSA (body surface area)?
BSA calculations involve various formulas that are used to calculate BSA (m 2) by using Weight (kg), height (cm). Here is a body surface area chart estimating average BSA of adults and children:
What is body surface area and why is it important?
Body surface area is used for a determining other medical measures. As examples, renal function is measured by the glomerular filtration rate (GFR) which is calculated in regard to the body surface area. The cardiac index is a measure of cardiac output divided by the body surface area, giving a better approximation of the required cardiac output.
What is the most widely used body surface area equation?
The DuBois and DuBois (Arch Intern Med 1916;17:863-71) BSA equation is the most widely used, … Values for body surface area (BSA) are commonly used in medicine, particularly to calculate doses of chemotherapeutic agents and index cardiac output.
