The Parkland formula is used to estimate initial fluid resuscitation requirements in burn patients. A common formula is 4 mL × body weight in kg × percent total body surface area burned.

Half of the calculated volume is typically given during the first 8 hours from the time of the burn, and the remaining half is given over the next 16 hours.

The first 8-hour period starts from the time of the burn injury, not from the time the patient arrives at the hospital.

No. The Parkland formula provides an initial estimate only. Ongoing resuscitation should be adjusted based on urine output, hemodynamics, lactate, and the overall clinical picture.
