Parkland Burn Formula IV Fluid Resuscitation Calculator

Calculate initial Lactated Ringer's IV fluid resuscitation requirements for acute second- and third-degree thermal burns using the Parkland / Baxter formula.

Rule of Nines (exclude 1st-degree superficial erythema)
First 50% must be given within 8 hours of INJURY TIME, not hospital arrival

Calculation Results

Total 24-Hour Lactated Ringer's Volume: 10,500 mL (10.5 Liters) 4 mL × 75 kg × 35% TBSA
First 8 Hours Fluid Infusion Rate: 875 mL / hour (5,250 mL infused over remaining 6.0 hrs)
Next 16 Hours Fluid Infusion Rate: 328 mL / hour (Remaining 5,250 mL over 16 hrs)
Clinical Target Urine Output: 37 - 50 mL / hour (0.5 mL/kg/hr)

Frequently Asked Questions

What is the Parkland formula for burn resuscitation?

The classic Parkland (Baxter) formula calculates 24-hour crystalloid (Lactated Ringer's) fluid requirements for severe burns: Volume (mL) = 4 mL x Weight (kg) x %TBSA burn. The first half is administered over the first 8 hours from time of injury, and the remaining half over the next 16 hours.

Why does the first 8-hour clock start from the time of injury?

Massive capillary leak and fluid extravasation begin immediately upon thermal injury. If a burn patient arrives at the trauma center 3 hours after the accident, the entire first 50% volume must be infused over the remaining 5 hours.

What IV fluid is indicated for burn resuscitation?

Lactated Ringer's (LR) is the standard crystalloid. Normal saline (0.9% NaCl) is avoided because large infusion volumes cause severe hyperchloremic metabolic acidosis.

What is the primary clinical endpoint used to titrate IV fluid rates?

Urine output is the gold standard indicator of end-organ perfusion. In adults, fluids are titrated to maintain a target urine output of 0.5 mL/kg/hour (30 to 50 mL/hr).
