A 45-year-old construction worker sustains full-thickness burns over 35% TBSA. Parkland formula for fluid resuscitation in the first 24 hours after a burn injury requires calculation of 4 mL × weight (kg) × %TBSA burned. For a 70 kg patient with 35% TBSA burn, how much Ringer's lactate should be given in the first 8 hours?
- A 4900 mL ✓
- B 3920 mL
- C 9800 mL
- D 2450 mL
Correct answer: A. 4900 mL
Explanation
Parkland formula: Total fluid in 24 hours = 4 × 70 kg × 35 = 9800 mL Ringer's lactate. Half of this (4900 mL) is given in the first 8 hours from the time of injury (not from admission), and the remaining half (4900 mL) is given over the next 16 hours. The 8-hour clock starts from the time of burn injury, not arrival at hospital. Therefore, 4900 mL should be administered in the first 8 hours. Children require additional maintenance fluid (D5 Ringer's lactate or 0.45% NaCl). The Parkland formula is used for burns >20% TBSA in adults.
