Burn Fluid Resuscitation (Parkland) Calculator

Burn Fluid Resuscitation (Parkland) Calculator for Emergency. The 24-hour period starts at injury, not hospital arrival. A delayed presentation therefore requires reconciliation of elapsed time and fluids already given. The tool intentionally does not turn a remaining volume into a catch-up rate; ongoing perfusion, urine output, fluid balance and specialist assessment determine titration.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

The historical Parkland volume is 4 times body weight in kilograms times burned TBSA expressed in percentage points, yielding milliliters over the first 24 hours. The comparison output uses 2 mL/kg/%TBSA, the ABA 2024 recommended starting volume for its adult population with burns of at least 20% TBSA. Both arithmetic results retain the same measured weight and burn-area estimate.

When to use this calculator

Use this side-by-side calculation for learning or checking a burn-team estimate in the stated adult thermal-burn population. The guide does not prescribe resuscitation for smaller burns, children, electrical injury or special physiological circumstances. Superficial epidermal burns are not included in the TBSA input.

Inputs used

  • Adult thermal burn, partial/full-thickness TBSA at least 20%, assessed by the burn team?
  • Body weight (kg)
  • Partial/full-thickness burned TBSA (%)

Clinical interpretation

The 24-hour period starts at injury, not hospital arrival. A delayed presentation therefore requires reconciliation of elapsed time and fluids already given. The tool intentionally does not turn a remaining volume into a catch-up rate; ongoing perfusion, urine output, fluid balance and specialist assessment determine titration.

Worked example

For a 70 kg adult with 30% qualifying TBSA, the historical calculation is 4 x 70 x 30 = 8400 mL. The ABA initial-volume comparison is 2 x 70 x 30 = 4200 mL. These are different starting frameworks, not an acceptable range from which to choose arbitrarily.

Limitations and safety notes

Neither number is a fixed requirement or a ceiling. Measurement errors in TBSA are multiplied by weight and coefficient, so an area estimate should be checked before using the result. No urine-output protocol, colloid algorithm or pediatric maintenance allowance is implemented. The ABA publication is cited, not reproduced or presented as endorsing this software.

Frequently asked questions

Why show two different volumes?

The named historical formula uses 4 mL/kg/%TBSA, while the ABA 2024 guideline recommends starting eligible adults at 2. The difference is clinically important.

Does 30% mean I enter 0.30?

No. Enter 30 percentage points. Weight in pounds is converted to kilograms by the unit selector.

Does the output tell me the infusion rate?

No. It does not account for elapsed time, prior fluids or response sufficiently to prescribe a rate.
