Burns are classified by depth and TBSA. What does TBSA stand for?

When evaluating burns, clinicians quantify how much of the body’s surface is affected, in addition to how deep the burns are. The standard term for the burned extent is Total Body Surface Area, abbreviated TBSA. This percentage expresses the burned portion of the entire body surface and is used to guide fluid resuscitation, treatment decisions, and prognosis. TBSA is estimated with charts like the rule of nines or the Lund and Browder chart, which adapted measurements help account for age and body proportions. For example, fluid needs are often calculated using the Parkland formula, which uses TBSA to determine the total fluid volume over the first 24 hours (4 mL × body weight in kg × TBSA%). Half of that is given in the first 8 hours, with the remainder over the next 16 hours. The correct term is Total Body Surface Area, not variants like Total Body Skin Area or Thermal Burn Surface Area, which are not the standard measurements used in burn assessment.
