Using the parkland formula, calculate the hourly rate of fluid replacement with lactated ringerâs solution during the first 8 hours for a client weighing 75 kg with total body surface area (tbsa) burn of 40%. record your answer using a whole number.

The Parkland formula is

V = 4mA

where

V = volume of replacement fluid (mL) required within the first 24 hours after a burn injury,

m = body mass, kg

A = percent of body surface area covered with burns.

The first half of the fluid should be delivered in the first 8 hours.

Because we are concerned with fluid replacement within the first 8 hours, the Parkland formula is valid to be used.

Given:

m = 75 kg

A = 40%

Therefore

V = 4*75*40 = 12,000 mL = 12 L

This is the fluid replacement required in the first 24 hours.

Because half of this amount should be delivered in the first 8 hours, the amount of fluid replacement is

6,000 mL in 8 hours, or

6000/8 = 750 mL per hour.

Answer: 750 mL every hour
