How is fluid repletion calculated for burn patients according to the Parkland formula?

The Parkland formula is a crucial tool used in the management of burn patients to calculate the amount of fluid resuscitation needed in the first 24 hours post-injury. The formula states that the total volume of crystalloid fluids required in this time frame is given by multiplying the patient's weight in kilograms by the percentage of total body surface area (TBSA) burned and then by 4 mL.

Therefore, the correct formulation is:

Total volume of fluids in the first 24 hours (mL) = 4 mL x body weight in kg x % TBSA burned.

This allows for adequate resuscitation of burn patients, taking into consideration their weight and the extent of their injuries. The combination of these parameters helps to guide clinicians in providing the necessary fluids to restore and maintain blood volume, support organ function, and prevent shock after significant burn injuries.

This formula specifically highlights the importance of the percentage of the body surface area affected by the burn, making it adaptable for patients with varying degrees and extents of burns. The fluid is typically administered in a two-phase approach, with half of the calculated volume given in the first 8 hours and the remaining half over the next 16 hours. By using this approach, caregivers
