d) 6 lt
Show Answer
Correct Answer – B
Answer: B. 4 lt
Parkland formula most commonly used IV fluid – Lactated Ringer’s Solution
Fluid calculation
- 4 x weight in kg x %TBSA burn
- Give 1/2 of that volume in the first 8 hours
- Give other 1/2 in next 16 hours
- Warning: Despite the formula suggesting cutting the fluid rate in half at 8 hours, the fluid rate should be gradually reduced throughout the resuscitation to maintain the targeted urine output, i.e., do not follow the second part of the formula that says to reduce the rate at 8 hours, adjust the rate based on the urine output.
Example of fluid calculation - 50-kg man with 40% TBSA burn
Parkland formula: - 4 x 50 x 40 = 8,000 ml
- Give 1/2 in first 8 hours = 4,000 ml in first 8 hours
- Adjust fluid rate to maintain urine output of 50 ml/hr
