Worked Example: Reference Calculation: Parkland Burn Fluid

Compute Parkland 4 mL/kg/%TBSA resuscitation schedule split 50% / 50%.

  1. Enter the reagent concentrations, assay readings, or clinical laboratory parameters.
  2. Compute the standard formula: Total24h_mL = 4 mL × Weight_kg × %TBSA; First8h_mL/hr = (Total24h / 2) / 8; Next16h_mL/hr = (Total24h / 2) / 16.
  3. Review the primary result, supporting reference intervals, and 3 SVG visualizations.
Result: Evaluates Parkland Burn Fluid via Total24h_mL = 4 mL × Weight_kg × %TBSA; First8h_mL/hr = (Total24h / 2) / 8; Next16h_mL/hr = (Total24h / 2) / 16.

Parkland Formula 24-Hour Burn Resuscitation & 8-Hour Infusion Rate Calculator: inputs, method, and how to read the result

Compute Parkland 4 mL/kg/%TBSA resuscitation schedule split 50% / 50%.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Patient Weight Kg: Patient body weight in kilograms.
  • Burn Tbsa Pct: Second- and third-degree burn Total Body Surface Area (% TBSA).

What the calculation includes

With the default values shown, Total 24-Hour Crystalloid Volume is 8,000 mL. The calculation follows Parkland Burn Fluid Reference Equation; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Patient Weight Kg from 80 kg to 88 kg changes Total 24-Hour Crystalloid Volume from 8,000 mL to 8,800 mL. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses standard IUPAC atomic weights, 25°C (298.15 K) reference thermodynamics, and published clinical literature equations.
  • Educational and laboratory reference tool only; clinical scoring calculators do not replace professional medical judgment or institutional protocols.

Scope: IUPAC / NIH Laboratory & Clinical Reference Standard Check the assumptions and limitations against your situation before relying on the estimate.
