A 24-year-old with 50% total body surface area burns requires fluids. According to the Parkland formula, how much LR is needed in the first 24 hours for a 75 kg patient with 50% burns?

A 24-year-old with 50% total body surface area burns requires fluids. According to the Parkland formula, how much LR is needed in the first 24 hours for a 75 kg patient with 50% burns?

• A. 12 L
• B. 15 L
• C. 20 L
• D. 8 L

Answer: (B)

Parkland formula uses 4 mL of lactated Ringer’s solution per kilogram of body weight per percent TBSA burned to estimate fluid needs in the first 24 hours after a burn. For this patient: 4 mL × 75 kg × 50% = 15,000 mL, or 15 L in the first 24 hours. Half of that (7.5 L) should be given in the first 8 hours from injury, with the remaining 7.5 L over the next 16 hours. Therefore, the total LR needed in the first 24 hours is 15 L.
