Burn fluid resuscitation: historical estimates

Calculates a theoretical 24-hour volume using explicitly selected coefficients and records the volume already administered. Does not provide a recommended infusion rate or replace clinical titration.

Calculate with transparency

Check the population, units and version. The result shows the formula or classification; it does not make an automatic treatment decision.

Method · Limits of application

Baxter–Shires 1968 / modified Brooke; mathematical comparison in adults

ABA 2024 recommends starting the estimate with 2 mL/kg/% in adults with burned TBSA ≥ 20%. Parkland 4 is an explicitly selected historical comparison. This is not a recommended infusion rate and does not replace monitoring-guided titration.

Conditions of use

Check the conditions of application before calculating. The result presents the documented formula or criteria; it does not establish a diagnosis or prescription.

Method version

Baxter–Shires 1968 / modified Brooke; mathematical comparison in adults

Formula and criteria

Theoretical 24 h total = coefficient × weight × burned TBSA. The first half corresponds to the first 8 h after the burn. Remaining = maximum of zero and (theoretical total − volume already administered).

Population and limitations

Synthetic cases checked (4)

Synthetic cases for checking the implementation, with no patient data.
