Parkland formula is used for which patients?

• A. Burn victims
• B. Stroke victims
• C. Sepsis
• D. Renal failure

Answer: (A)

The Parkland formula is used to guide fluid resuscitation in patients with major burn injuries. When a large burn disrupts the skin, huge fluid losses and inflammatory responses can cause hypovolemia, so rapidly establishing the right amount of IV fluid is crucial to maintain tissue perfusion. The formula calculates the total fluid for the first 24 hours as 4 mL × body weight in kilograms × percent TBSA burned, with Lactated Ringer’s as the usual fluid. Half of that volume is given in the first 8 hours from the time of burn, and the remaining half over the next 16 hours. This timing matches the period of greatest capillary leak and fluid loss, helping prevent shock and organ dysfunction. Monitor response with urine output (about 0.5 mL/kg/hr in adults, with adjustments for children) and adjust as needed to avoid overload. This approach is specific to burn injuries and isn’t used for stroke, sepsis, or renal failure, where fluid management depends on different causes and targets.
