A 30-year-old woman sustains 35% TBSA full-thickness burns. Using the Parkland formula, the fluid requirement in the first 8 hours from the time of injury (not from hospital arrival) is: (Patient weight 60 kg)

• A 4200 mL Ringer's lactate ✓
• B 2100 mL Ringer's lactate
• C 8400 mL Ringer's lactate
• D 3150 mL Ringer's lactate

Explanation

Parkland formula: 4 mL x weight (kg) x %TBSA = total fluid in 24 hours. For this patient: 4 x 60 x 35 = 8400 mL total in 24 hours. Half (4200 mL) is given in the first 8 hours from time of burn injury; the remaining half (4200 mL) is given over the next 16 hours. Ringer's lactate is the resuscitation fluid of choice. The 8-hour clock begins from the time of injury, not hospital arrival.
