The Parkland formula calculates the volume of Lactated Ringer's required for fluid resuscitation in burn patients over the first 24 hours. Accurate TBSA estimation and weight are essential for appropriate resuscitation.
Parkland Formula
If patient arrived delayed, enter hours elapsed since burn to adjust first-period rate.
How to Use the Parkland Formula Calculator
The Parkland formula calculator computes burn resuscitation fluid volumes. Enter the patient's weight and the TBSA of partial or full-thickness burns.
Example Calculation
A 70 kg patient with 25% TBSA burns: 4 × 70 × 25 = 7,000 mL LR over 24 hours. 3,500 mL in the first 8 hours (437 mL/hr) and 3,500 mL over the next 16 hours (219 mL/hr). If the patient arrives 2 hours after the burn, give 3,500 mL in the remaining 6 hours (583 mL/hr).
Clinical Considerations
The Parkland formula is a starting estimate. Actual resuscitation should be titrated to urine output (target 0.5–1 mL/kg/hr in adults). Avoid over-resuscitation (fluid creep), which can cause abdominal compartment syndrome. Use the Lund-Browder chart for pediatric TBSA estimation.
FAQ
Is this Parkland formula calculator free?
Yes, completely free with no signup required. Always confirm with burn specialist guidance.
What is the Parkland formula?
Parkland formula: 4 mL × weight (kg) × %TBSA burned = total volume of Lactated Ringer's over 24 hours. Half is given in the first 8 hours from time of burn, and the other half over the next 16 hours.
What fluid is used in the Parkland formula?
Lactated Ringer's (LR) solution is the standard fluid. Normal saline is avoided for large-volume resuscitation due to hyperchloremic acidosis risk. Colloids may be added after 24 hours.
When is the 8-hour clock started?
The 8-hour clock starts at the time of the burn, not at hospital arrival. If a patient arrives 2 hours after the burn, the first half of fluids must be given in the remaining 6 hours.
What burns are included in the Parkland calculation?
Only partial-thickness (second-degree) and full-thickness (third-degree) burns count toward the TBSA percentage. Superficial (first-degree) burns are excluded.
