Burns Fluid Resuscitation
The Parkland Formula Calculator estimates first-24-hour IV fluid resuscitation volumes for a burns patient using the Modified Parkland Formula (3 mL x %TBSA x weight in kg) with Lactated Ringer's Solution. It splits the total into a Phase 1 rate (first 8 hours from the time of burn, adjusted for any fluid already given and for time already elapsed) and a Phase 2 rate (the remaining half over the following 16 hours), and separately calculates a Holliday-Segar maintenance fluid rate to run alongside resuscitation fluid. It also includes a Rule of Nines reference table for estimating %TBSA by age band and flags that this method is less accurate in children, linking out to the app's Lund & Browder Chart calculator for paediatric TBSA estimation.
This calculator uses the Modified Parkland Formula at 3 mL/kg/%TBSA of Lactated Ringer's Solution for the total 24-hour volume, split into the Phase 1 and Phase 2 rates described in the tool.
No — the app instructs entering the actual time elapsed since the burn injury itself, not since hospital arrival, and caps entry at 7 hours (enter 7 if more time has passed).
Separately — the calculator computes a Holliday-Segar maintenance rate that is meant to be prescribed and run as its own IV line, in addition to the Parkland resuscitation fluid.
Because children's body proportions, especially head and legs, differ from adults', the app flags this limitation directly and links to its Lund & Browder Chart calculator for more precise paediatric %TBSA estimation.
The tool lists a paediatric target of 1 mL/kg/hr and an adult target of 0.5-1 mL/kg/hr (30-50 mL/hr), with guidance to increase the rate 10-20% if urine output is below target and decrease it 10-20% if above target.
