How is the Parkland burn formula calculated?

The Parkland burn formula is specifically designed to estimate the fluid resuscitation needs for burn patients in the first 24 hours following a burn injury. The correct approach involves taking into account both the patient’s weight and the percentage of total body surface area (TBSA) that has been burned.

Using the formula, the calculation is performed by multiplying the weight of the patient in kilograms by 4 mL for every percentage of TBSA burned. This means that for a patient who has a certain percentage of their body burned, you would compute the total fluid requirement by considering both their weight and the extent of the burn injury. The resulting number is the total volume of crystalloids required in the first 24 hours, with half of this volume administered in the first 8 hours post-injury and the remainder over the following 16 hours.

This formula is crucial in the management of burn victims, as proper fluid resuscitation can significantly impact outcomes in severe burn injuries. It's also worth noting that this calculation reflects the need for a more aggressive resuscitation approach in patients with larger burns, as opposed to less extensive injuries, which is why simply multiplying by other factors (like 1 mL, 2 mL, or 3 m
