When sodium, bicarbonate, osmolality, or an infusion rate is changing, clean arithmetic matters. Parkland Formula Calculator focuses on the exact variables shown in the tool and returns the estimate its engine supports.

What this calculator does

Parkland Formula Calculator uses Adult or child, Weight, Head burn, Torso burn, Arm burn, Additional arm burn, Leg burn, and the remaining fields shown to calculate Parkland resuscitation-fluid estimate. Where supported, it also shows TBSA used, First 8 hours, and Next 16 hours so the primary result is easier to check. It follows the exact field flow and engine behavior in this plugin rather than describing a different calculator with the same name. Fluid and electrolyte formulas are sensitive to units, timing, ongoing losses, kidney function, and rapidly changing physiology. They are most useful as structured estimates alongside repeat measurements and bedside assessment.

How to use it

Enter or select Adult or child, Weight, Head burn, Torso burn, Arm burn, Additional arm burn, and the remaining fields shown. Use the units offered by the calculator and keep paired laboratory or treatment values from the same clinical episode whenever the formula assumes that. If an entry is unknown, do not substitute a guess simply to obtain a number.

How the calculation works

If you enter a total burn percentage directly, the calculator uses it; otherwise it sums the body-area burn entries. It then multiplies weight × TBSA × 4 mL for adults or 3 mL for children, with half of the calculated 24-hour volume shown for the first 8 hours and half for the next 16 hours.

Example

Using the sample values prefilled in this calculator, the primary result is 10080 mL / 24 h (Parkland resuscitation fluid), TBSA used is 36%, and First 8 hours is 5,040 mL. This example demonstrates the plugin’s own calculation path; replace the sample inputs with verified values before interpreting a real result.

How to interpret the result

Treat the volume as a starting 24-hour resuscitation estimate. The clinically important interpretation comes from response to fluids, urine output, perfusion, and burn-team reassessment.

Limitations and notes

Parkland is an initial burn-resuscitation estimate, not a fixed prescription. Timing is counted from the burn, not arrival, and fluids should be titrated to clinical endpoints. Pediatric burns may require maintenance glucose-containing fluids in addition to resuscitation.
