Fluid resuscitation in burns (Parkland formula)
Surgery · exam-style practice question with explanation
Using the Parkland formula, how much fluid does a 60 kg adult with 30% total body surface area burns need in the first 24 hours, and how is it given?
- A. 1,800 mL, all in the first 8 hours
- B. 3,600 mL, evenly over 24 hours
- C. 7,200 mL, half in the first 8 hours from the time of the burn
- D. 7,200 mL, half in the first 16 hours
Show the answer and explanation
Answer: C. 7,200 mL, half in the first 8 hours from the time of the burn
The Parkland formula is 4 mL × body weight (kg) × % TBSA burned of crystalloid such as Ringer's lactate: 4 × 60 × 30 = 7,200 mL. Half is given in the first 8 hours counted from the time of the burn, and the rest over the next 16 hours. Adjust to urine output.
Key point: Parkland: 4 mL × kg × %TBSA; half in the first 8 hours from the burn.
