Parkland formula

The Parkland formula is a burn formula used to estimate the amount of replacement fluid required for the first 24 hours in a burn patient so as to ensure they remain hemodynamically stable. The milliliter amount of fluid required for the first 24 hours -usually Ringer's lactate- is four times the product of the body weight and the burn percentage (i.e. body surface area affected by burns). The first half of the fluid is given within 8 hours from the burn incident, and the remaining over next 16 hours. Only area covered by second-degree burns or greater is taken into consideration, as first-degree burns do not cause hemodynamically significant fluid shift to warrant fluid replacement.
