Parkland Formula

The Parkland formula is used to estimate the required amount of replacement fluid such as blood etc., for the first 24 hours for a burn patient. The Parkland formula is mathematically expressed as V = 4 x Wt x BSA % where, Wt is the mass (weight) of the person in Kg, BSA % is the total burnt surface area of the body in percentage, and V is the volume in milliliters (mL). The formula uses the rule of nine to calculate the burn replacement amount.

Rule of Nine Burn Formula

Formula:

According to Parkland Formula
H24 = 4 * Wt * %BSA
H8 = H24 / 2
H16 = H24 / 2


Where,

Wt = Patient Weight
%BSA = Body Surface Area Affected
H24 = Total Fluid Over First 24 Hours
H8 = Fluid Over First 8 Hours
H16 = Fluid Over Next 16 Hours

Consider for example, a person weighing 65 kg with burns to 5% of his or her body surface area would require 4 x 65 x 5 = 1,300 mL of fluid (Blood or other serum) replacement within 24 hours. The first half is given in first 8 hours, and the other half in next 16 hours. The formula is based on the rule of nine and the rule is as follows :

Rule of Nine :

For Adults :
Each Arm : 9 %
Each Leg : 18 %
Head : 9%
Front Torso : 18 %
Back Torso : 18 %

For Children :
Each Arm : 9 %
Each Leg : 14 %
Head : 18%
Front Torso : 18 %
Back Torso : 18 %
