Summary
Dysnatremia is the most common electrolyte disorder in elderly ICU patients; encompassing both hyponatremic and hypernatremic conditions. Dysnatremia is the most common electrolyte disorder in hospitalized patients. It is a common finding at Intensive Care Unit (ICU) admission [1,2,3]. Hyponatremia is a pathologic condition defined as a serum sodium < 135 mmol/L. It is the most common electrolyte disorder in hospitalized patients. Presence of severe hyponatremia on hospital admission has been demonstrated to be independently associated with an increased risk for ICU admission and poor prognosis [5]. Hyponatremia is often a marker of severity of underlying disease [6,7]
