The Hospitalist’s Role in the Perioperative Management of Hyponatremia
Hyponatremia is the most common electrolyte abnormality that occurs in hospitalized patients, and it is recognized as a serious in-hospital complication. It is a complex electrolyte disorder that results mainly from water imbalances and dysregulation of arginine vasopressin. Hyponatremia is associated with increased morbidity and mortality among geriatric patients and patients with heart, liver, or neurologic diseases. The following educational activity discusses the pathophysiology of hyponatremia, outlines methods for differentiating the cause, and provides examples of how to manage hyponatremia in various situations commonly faced by hospitalists.
