Question

Can you provide more information about the Parkland formula and how it is calculated, as well as the considerations for dividing the fluid replacement over the initial 8 hours and the subsequent 16 hours?

Answer 1

The Parkland formula calculates fluid needs for burn patients by using 4 mL of lactated Ringer's solution per kg of body weight per percent of TBSA burned, with half given in the first 8 hours and the remainder over the next 16 hours.

Step-by-step explanation:

The Parkland formula is used to calculate the total fluid replacement needed for burn victims in the first 24 hours after injury. It is calculated as 4 mL of lactated Ringer's solution per kilogram of body weight per percentage of total body surface area (TBSA) burned. During the initial 8 hours after the burn, half of the calculated fluid volume is administered, and the remaining half is given over the subsequent 16 hours. This division is crucial for preventing fluid overload and complications such as pulmonary edema.

Calculating Parkland Formula

Here's how to apply the Parkland formula:

1. Multiply the patient's weight (in kg) by the percentage of TBSA burned.
2. Multiply this result by 4 mL.
3. Administer 50% of the calculated volume in the first 8 hours from the time of the burn.
4. Give the remaining 50% over the next 16 hours.
