What is the expected urine output range for a patient with a crush injury?

For a patient with a crush injury, it is essential to monitor urine output as it can provide critical information about kidney function and overall fluid balance. The expected urine output range for such patients typically aligns with the body's physiological response to trauma and injury.

The correct answer indicates a range of 100-200 ml/hr, which is considered an appropriate output for maintaining adequate renal function in the context of a crush injury. This level of urine output suggests that the kidneys are effectively filtering blood and excreting waste products despite the potential for muscle injury, which can release myoglobin and other harmful substances into the bloodstream.

In cases of crush injuries, it is common to monitor for complications such as rhabdomyolysis, where muscle breakdown releases myoglobin; this can lead to problems such as acute kidney injury (AKI). Maintaining urine output within this expected range helps clinicians assess kidney health and can guide further treatment decisions.

Urine output lower than this range may indicate compromised renal perfusion or potential kidney damage, while outputs significantly higher could reflect excessive fluid resuscitation or other unrelated issues. Thus, understanding the normal urine output parameters for a patient with a crush injury is crucial for effective management and early detection of complications.
