Question

A patient weighing 187 lbs. has 38% total body surface area burns. Using the Parkland formula, how much fluid should this patient receive over the first eight hours after the burn occurred?

Record your answer as a whole number. ______

Answer 1

To calculate the fluid needs for the first 8 hours after a burn using the Parkland formula, convert the patient's weight to kilograms, then multiply by 4 mL and the percentage of body surface area burned. Divide this number by two to find the requirement for the first 8 hours, which for a patient weighing 187 lbs with 38% burns, is 6,460 mL.

Step-by-step explanation:

To calculate the fluid requirement for a patient using the Parkland formula, the following formula is used:

(4 mL × patient's weight in kg × percentage of total body surface area burned) ÷ 2 = Fluid requirement for the first 8 hours

First, we need to convert the patient's weight from pounds to kilograms by dividing by 2.2:

187 lb ÷ 2.2 = ~85.0 kg (rounded to the nearest whole number)

Then, we multiply 4 mL by the patient's weight in kilograms and the percentage of body area burned:

4 mL × 85.0 kg × 38% = 12,920 mL

Finally, we divide this number by 2 to get the fluid requirement for the first 8 hours:

12,920 mL ÷ 2 = 6,460 mL

Therefore, a patient weighing 187 lbs with 38% total body surface area burns should receive 6,460 mL of fluid over the first eight hours after the burn occurred.
