What is the goal of fluid resuscitation in crush injuries?

The goal of fluid resuscitation in crush injuries primarily focuses on correcting hypovolemia and diluting elevated potassium levels in the body. Following a crush injury, a significant release of myoglobin and potassium from damaged muscle cells into the bloodstream can occur, leading to complications such as acute kidney injury and hyperkalemia.

By administering fluids, particularly isotonic saline, medical personnel can help restore blood volume, ensuring adequate blood flow to organs and tissues while mitigating the risks associated with high potassium levels. This process involves supporting the kidneys' ability to filter excess potassium out of the bloodstream. Proper fluid resuscitation helps prevent potentially life-threatening complications and is crucial for stabilizing the patient following a crush injury.

The other choices, while relevant to fluid management in general, do not encapsulate the primary reasons for fluid resuscitation in the context of crush injuries.
