When treating a patient with a crush injury, which fluids can be used?

• A. Normal Saline
• B. Lactated Ringer's
• C. Dextrose 5% in water
• D. Albumin

Answer: (A)

Crush injuries require rapid volume expansion with an isotonic crystalloid to maintain kidney perfusion and flush out toxic myoglobin. The fluid of choice is normal saline because it stays in the intravascular space, expands volume effectively, and does not introduce potassium or sugar that could complicate rhabdomyolysis management. Lactated Ringer's contains potassium and lactate; with muscle breakdown, potassium shifts can worsen hyperkalemia, making this less ideal as a routine initial choice. Dextrose-containing fluids deliver free water after metabolism and can lead to hyponatremia and suboptimal resuscitation early on. Albumin, a colloid, is not routinely required for crush injury resuscitation and is more costly with less clear benefit in this setting. So, normal saline is the best initial fluid for managing crush injuries.
