What is the typical urine output for a patient diagnosed with severe head injury?

In cases of severe head injury, it is crucial to monitor urine output as an indicator of kidney function and overall fluid balance. The typical urine output for an adult is generally around 30-50 mL per hour, which translates to approximately 720 to 1200 mL over 24 hours.

Choosing 250 mL as a typical output in this scenario is reasonable because it can reflect a decreased urine output that may occur due to various factors associated with traumatic brain injury, including altered level of consciousness, hormonal imbalances, or indications of possible brain injury-related complications such as diabetes insipidus.

Furthermore, this output is significant when considering potential changes in renal perfusion and function resulting from trauma. Urine output tends to decrease in the acute phase following a severe head injury, making 250 mL a plausible value if one considers monitoring over a shorter period, such as a few hours, where the output might be lower due to inflammatory responses or fluid accumulation.
