Question: 1 / 830

According to the Parkland formula, how much crystalloid should be administered per hour to a 70-kg patient with severe burns to 50% of his BSA?

300-400 mL

500-600 mL

800-900 mL

The Parkland formula is a widely recognized guideline used to estimate the fluid resuscitation needs for patients with severe burns. According to this formula, the total volume of crystalloid solution required in the first 24 hours after the burn injury is calculated using the patient's weight in kilograms and the percentage of total body surface area (BSA) burned. The formula is:

Total fluid = 4 mL x Body Weight (kg) x %BSA burned.

For a 70-kg patient with burns covering 50% of the BSA, the total fluid needed in the first 24 hours would be calculated as follows:

Total fluid = 4 mL x 70 kg x 50 = 14,000 mL.

This total is to be given over the first 24 hours, so to find the hourly rate, you divide the total volume by 24 hours:

Hourly fluid rate = 14,000 mL / 24 hours ≈ 583 mL per hour.

This value falls within the range of 500-600 mL, which suggests that the option indicating 800-900 mL would be an overestimation for the initial hourly rate and would not adhere to the guidelines provided by the Park
