In burn wound management, estimating the total burned surface area (TBSA) is critical for fluid resuscitation; misestimating by more than what percentage can increase morbidity?

In burn wound management, estimating the total burned surface area (TBSA) is critical for fluid resuscitation; misestimating by more than what percentage can increase morbidity?

• A. 5 percent
• B. 10 percent
• C. 15 percent
• D. 20 percent

Answer: (B)

Accurate TBSA estimation is crucial because it directly drives fluid resuscitation calculations. In burn management, formulas allocate a large volume of fluids based on how much of the body is burned; a misestimate changes the total fluids given in the first 24 hours and can push the patient toward under-resuscitation or over-resuscitation. Misestimating by about 10 percentage points can create a substantial fluid difference—roughly a few liters in a typical adult—which increases the risk of hypoperfusion and shock if under-resuscitated, or edema, pulmonary complications, and renal strain if over-resuscitated. That’s why errors beyond 10% in TBSA estimation are associated with higher morbidity. Smaller errors have less impact on the overall fluid plan.
