The Parkland fluid resuscitation formula for burn patients is used as follows: LR solution (4 mL/kg/% total body surface area burned) is administered intravenously in the first 24 hours, half of the volume is to be given in the first 8 hours and the other half over the next 16 hours. In this case, 40% × 4 mL/kg × 80 kg = 12,800 mL, half 6,400 mL over the first 8 hours.
