What is the acceptable urine output for a trauma patient?

In trauma patients, monitoring urine output is critical as it serves as an important indicator of renal perfusion and overall fluid status. An acceptable urine output for an acute care setting, particularly following trauma, is generally considered to be around 0.5 mL/kg/hour. For an average adult weighing around 70 kg, this translates to approximately 30 mL/hour. Therefore, a urine output of 50 cc/h is above the minimum threshold and reflects adequate kidney function and perfusion, especially important in trauma management.

A urine output below 30 cc/h may raise concern regarding renal perfusion and could indicate potential issues such as hypovolemia or renal failure. Values like 15 cc/h would be indicative of oliguria and warrant immediate investigation. Meanwhile, a urine output of 100 cc/h, although reflecting well-functioning kidneys, would generally be considered excessive in a trauma context and may suggest fluid overload or other underlying issues. Thus, while all these values are important indicators in clinical practice, the choice reflecting a balance of adequacy and safety in a trauma setting is appropriately represented by 50 cc/h.
