Classic Parkland Formula for Adult Burns

Classic Parkland calculates 4 mL multiplied by a protocol-selected calculation weight in kilograms and qualifying burn TBSA percentage for the first 24 hours after a burn. This page reports that historical formula arithmetic and its fixed 50/50 allocation only.

The classic formula allocates one half of its unrounded total to the first 8 hours from burn occurrence and one half to the following 16 hours. This calculator does not convert either allocation into a fluid rate.

The historical formula’s first 8-hour allocation is measured from the time of injury rather than arrival. This page does not calculate delayed-resuscitation, prior-fluid, remaining-volume, or catch-up-rate arithmetic.

Use a qualifying burn TBSA assessment, not ordinary height-and-weight body surface area. The page describes superficial partial-thickness, deep partial-thickness, and full-thickness burns, while excluding superficial erythema, sunburn, and epidermal or first-degree burns.

No. It does not determine whether a person meets a resuscitation indication, whether intravenous fluid should begin, or which protocol applies.

This page preserves the classic 4 mL/kg/%TBSA Parkland model. The 2024 American Burn Association guideline addresses adults with burns at least 20% TBSA and recommends a 2 mL/kg/%TBSA starting approach to reduce total fluid, followed by response-guided titration. That separate approach is not calculated here and must not be mixed into this result.

Classic Parkland is the historical 4 mL/kg/%TBSA crystalloid formula. Modified Brooke is a separate lower-volume burn-resuscitation approach and is not calculated, ranked, or substituted by this page. The applicable burn-center protocol determines which approach, if any, is used.

This page limits itself to the classic first-day crystalloid arithmetic. Historical Parkland descriptions also included a later plasma context, but this calculator does not calculate any subsequent-day volume, plasma component, or treatment plan.

The applicable burn-center protocol chooses the calculation weight. This calculator accepts a submitted value in kilograms or pounds, converts pounds to kilograms without rounding before the formula, and does not choose actual, ideal, adjusted, or obesity-specific weight.

No. Pediatric body proportions, formulae, glucose needs, and maintenance-fluid requirements differ. This page does not calculate a pediatric formula or add pediatric maintenance fluid.

No. The page intentionally provides no hourly rate, catch-up calculation, prior-fluid adjustment, or remaining-volume plan. Those decisions require the applicable protocol and ongoing clinical assessment.

Fluid creep describes delivered burn-resuscitation volume exceeding formula estimates. Formula arithmetic should not be followed blindly; actual management requires response-guided reassessment.

They can change real-world assessment and fluid needs. This calculator does not adjust for those contexts or decide a treatment plan.

Sources: [3, 4, 5]

No. Reaching or exceeding a formula estimate neither proves fluid was appropriate nor means fluid should stop. Ongoing urine output, perfusion, and burn-center protocol assessment remain necessary.

Sources: [3, 4, 5]

No. It is an educational calculation of one historical first-day formula and does not diagnose burn severity, prescribe treatment, or replace a burn-center pathway.
