Approach to Polyuria in the ICU
摘要
Polyuria, defined as urine output exceeding 3 L per day in adults, is a significant concern in critically ill patients. It can lead to dehydration, electrolyte imbalances, and hemodynamic instability, complicating the management of patients in the Intensive Care Unit (ICU). Polyuria may result from various etiologies, including endocrine disorders, renal dysfunction, fluid imbalances, or as an adverse effect of medications.
