When abdominal compartment syndrome is suspected, decreased urine output is a critical symptom to monitor closely. This condition occurs when the pressure within the abdominal cavity increases to a level that compromises the function of the abdominal organs and can affect renal perfusion.

Decreased urine output typically signals renal impairment, which can occur due to inadequate blood flow to the kidneys caused by elevated intra-abdominal pressure. As the kidneys receive less perfusion, their ability to filter waste and produce urine diminishes, leading to oliguria or anuria. Thus, monitoring urinary output is essential for early detection of renal compromise and progression of compartment syndrome.

The other symptoms mentioned, such as increased serum sodium levels, elevated hemoglobin levels, and increased appetite, are not directly associated with abdominal compartment syndrome and do not provide immediate, actionable insights into the state of the patient's renal function or the severity of the condition. In acute settings, a focus on renal function, as indicated by urine output, is paramount for effective management and intervention.
