Total body surface area
Total Body Surface Area (TBSA)
Total Body Surface Area (TBSA) is a measure of the percentage of the body covered by burns, used to help guide treatment decisions including fluid resuscitation and becomes part of the guidelines to determine transfer to a burn unit.
Pronunciation
To-tal Body Sur-face Area
Etymology
The term "Total Body Surface Area" is derived from the English language. "Total" comes from the Latin word "totus", meaning whole. "Body" is derived from the Old English "bodig", meaning the physical structure of a human. "Surface" comes from the French "surface", meaning the outside part or uppermost layer of something. "Area" is derived from the Latin "area", meaning a vacant piece of level ground.
Calculation
The calculation of TBSA is critical for the prognosis and treatment of burn patients. The most common method of estimating TBSA is the Rule of Nines, which allocates 9% (or multiples thereof) to major body parts. Another method is the Lund and Browder chart, which provides a more accurate way of estimating TBSA in children.
