In Crush Syndrome, what is the recommended Normal Saline bolus for adults?

• A. 1 liter
• B. 0.5 liter
• C. 2 liters
• D. 750 ml

Answer: (A)

In crush injury management, the priority is rapid volume restoration to support kidney perfusion and help flush out myoglobin released from damaged muscles. An adult is typically given about 1 liter of normal saline as an initial bolus. This amount provides a quick boost in intravascular volume to improve blood pressure and urine output without overloading a patient who may have concurrent injuries or evolving edema. Smaller amounts, like 0.5 liter or 750 mL, may not restore perfusion quickly enough, while a large 2-liter bolus can risk fluid overload in some patients. After the bolus, continue isotonic fluids at a brisk rate with careful monitoring to achieve a urine output goal (often around 200–300 mL/hour in adults) and adjust based on response and signs of fluid balance.
