According to the material, half of the Parkland-calculated fluid should be given in which time frame?

• A. In the first 4 hours
• B. In the first 12 hours
• C. In the first 8 hours
• D. In the first 24 hours

Answer: (C)

In burn resuscitation, fluids are guided by the Parkland formula: 4 mL × body weight (kg) × %TBSA burned, given as lactated Ringer’s in the first 24 hours. The key timing rule is that half of that total should be infused in the first 8 hours from the time of burn, with the remaining half given over the next 16 hours. This early surge matches the period of greatest capillary leakage and fluid loss, helping to rapidly restore intravascular volume and tissue perfusion. If you start later, the goal is still to deliver half within the initial 8-hour window from injury. Monitor urine output to gauge adequacy (about 0.5 mL/kg/hr in adults, with adjustments for children). For example, a 70 kg patient with 50% TBSA burns would receive about 7 L in the first 8 hours and the other 7 L over the next 16 hours.
