Which burn fluid resuscitation formulas use Body Surface Area (BSA) in their calculations?

• A. Brooke Formula and Parkland Formula
• B. Brooke Formula Only
• C. Parkland Formula Only
• D. ISR Rule of Tens

Answer: (A)

In burn resuscitation, fluid needs are guided by how big the person is and how much of the body surface is burned. The amount you give depends on weight and the extent of burn expressed as percent TBSA. That percent TBSA ties directly to body surface area, so these formulas use body surface area in their calculations. The Parkland formula prescribes 4 mL per kg per percentTBSA burned, given over the first 24 hours with half in the first 8 hours. The Brooke formula uses 2 mL per kg per percentTBSA burned, also over 24 hours with half in the first 8 hours. Since both require the percent TBSA burned, they incorporate the body surface area aspect of the patient’s burn. The ISR Rule of Tens is a different, simpler heuristic and does not rely on the same weight × TBSA × 24-hour structure.
