A 50-year-old man with a 30% total body surface area burn is admitted 6 hours post-injury. Using the Parkland formula, what is the total fluid requirement for the first 24 hours, and how should it be administered?

• A 3 mL × weight (kg) × %TBSA; half in first 8 hours, half in next 16 hours
• B 2 mL × weight (kg) × %TBSA; one-third in first 8 hours, two-thirds in next 16 hours
• C 4 mL × weight (kg) × %TBSA; one-third in first 8 hours, two-thirds in next 16 hours
• D 4 mL × weight (kg) × %TBSA; half in first 8 hours, half in next 16 hours ✓

Explanation

The Parkland formula calculates 4 mL × body weight (kg) × %TBSA burn as the total crystalloid requirement for the first 24 hours. Half of this volume is given in the first 8 hours from the time of injury, and the remaining half over the subsequent 16 hours. This is the standard formula taught in ATLS and used in Indian burn management protocols.
