Which assessment best estimates burn surface area in adults?

• A. Rule of Nines
• B. Lund and Browder chart
• C. Palm method
• D. Burn depth scale

Answer: (A)

In burn assessment, quickly estimating total body surface area burned is crucial for guiding fluid resuscitation and treatment decisions. The Rule of Nines provides a fast, standardized way to approximate TBSA by assigning whole regions of the body fixed percentages (for adults, major regions like head, each arm, trunk, legs, and the perineum sum to 100%). This makes it easy to perform at the bedside and align with common resuscitation protocols, which is why it’s the best choice for estimating burn area in adults when speed and practicality matter. The Lund and Browder chart offers greater accuracy because it accounts for age-related body proportions, but it is more detailed and particularly advantageous for children; in adults, the advantage of speed with the Rule of Nines often makes it the preferred initial method. The palm method, while handy for very rough checks of small burns, is not reliable for estimating total burn area. A burn depth scale, on the other hand, measures how deep the injury is rather than how extensive it is, so it doesn’t estimate surface area.
