The Parkland formula for fluid resuscitation in burns calculates 4 mL × body weight (kg) × %TBSA burned of Ringer's lactate. For a 70 kg patient with 40% TBSA burns, total fluid in the first 24 hours is 11,200 mL. According to the Parkland formula protocol, how much is given in the first 8 hours?
- A 2800 mL
- B 3733 mL
- C 5600 mL ✓
- D 7467 mL
Correct answer: C. 5600 mL
Explanation
The Parkland formula gives half the total 24-hour volume in the first 8 hours from the time of burn (not from hospital admission), and the remaining half over the next 16 hours. For this patient: total = 4 × 70 × 40 = 11,200 mL. Half of 11,200 = 5,600 mL in the first 8 hours. The time is measured from the time of injury, so if the patient arrives 2 hours post-burn, the 5,600 mL must be delivered in the remaining 6 hours.
