About This Calculator

The Parkland formula (also known as the Baxter formula) estimates the total crystalloid fluid requirement for burn resuscitation in the first 24 hours following a major burn injury. It is one of the most widely used formulas for guiding initial fluid resuscitation in burn patients. The calculated volume is divided: half given in the first 8 hours from the time of burn, and the remaining half over the next 16 hours.

Formula

Total Fluid (mL) = 4 × Weight (kg) × BSA (%)
First 8 hours: 50% of total volume
Next 16 hours: 50% of total volume

Interpretation

Total Fluid (mL)Consideration
≤ 5,000Standard resuscitation
5,001 – 10,000Large volume — close monitoring
> 10,000Massive — risk of fluid overload

Frequently Asked Questions

What fluid is used in the Parkland formula?

The Parkland formula uses Lactated Ringer's solution (crystalloid). Colloid solutions are generally not given in the first 24 hours in the classic Parkland approach, though some modified protocols include colloid after 8–12 hours.

Why is the first 8 hours calculated from time of burn, not admission?

Fluid losses begin at the time of burn injury, not hospital arrival. The first 8 hours of resuscitation are measured from the time of the burn. Any prehospital fluids given should be subtracted from the first 8-hour volume.

What is fluid creep in burn resuscitation?

Fluid creep refers to the tendency to administer volumes exceeding the Parkland calculation. This can cause complications including abdominal compartment syndrome, pulmonary edema, and extremity compartment syndrome. Urine output (0.5–1 mL/kg/hr in adults) should guide titration.
