Name the Parkland formula and when it is used?

• A. 4 mL × body weight (kg) × %TBSA burned in first 24 hours; half in first 12 hours; rest over next 12 hours.
• B. 4 mL × body weight (kg) × %TBSA burned in first 24 hours; half in first 8 hours from time of burn; the rest over the next 16 hours; titrate to urine output.
• C. 2 mL × body weight (kg) × %TBSA burned in first 24 hours; half in first 6 hours; rest over 18 hours.
• D. 5 mL × body weight (kg) × %TBSA burned; distributed evenly over 24 hours.

Answer: (B)

The Parkland formula is a method for guiding fluid resuscitation in major burn patients. It uses 4 mL of fluid per kilogram of body weight per percent of TBSA burned to estimate the total fluid needed in the first 24 hours after the burn. The key timing is that half of that total volume should be given in the first 8 hours from the time of burn, with the remaining half given over the next 16 hours. The crystalloid most commonly used is Lactated Ringer’s, and the rate is adjusted based on urine output to ensure adequate perfusion without causing fluid overload (roughly 0.5 mL/kg/hour in adults). This approach explains why the correct option specifies 4 mL × body weight × %TBSA in 24 hours, with half in the first 8 hours and the rest over the next 16 hours, titrated to urine output. The other options either use the wrong multiplier, the wrong distribution over time, or omit the titration to urine output.
