For an 80-kg patient with burns over 30% TBSA, what is the calculated IV infusion rate of lactated Ringer's solution using the Parkland formula during the first 8 hours?

To determine the correct IV infusion rate of lactated Ringer's solution for a patient with burns using the Parkland formula, we need to apply the formula properly, which states that for the first 24 hours after a burn, 4 mL of fluid per kilogram of body weight per percentage of total body surface area (TBSA) burned should be administered.

For this patient:

1. Calculate the total fluid required for the first 24 hours:

• Weight of the patient: 80 kg

• TBSA burned: 30%

Using the Parkland formula:

[

\text{Total volume} = 4 , \text{mL} \times \text{weight (kg)} \times \text{TBSA (%)} = 4 , \text{mL} \times 80 , \text{kg} \times 30 = 9600 , \text{mL}

]

2. Determine the infusion rate for the first 8 hours:

Since this total volume is intended for the first 24 hours, to find the volume needed for the first 8 hours, we divide this total by 3 (
