Etiology, Clinical Approach, and Therapeutic Consequences of Hyponatremia
Goce Spasovski
Abstract:A perturbation in the water balance rather than any change in salt content is the main cause of hyponatremia, the most frequent electrolyte abnormality, defined as a serum sodium concentration <135 mEq/L. Hyponatremia may be divided between mild (Na > 120 mEq/L) or severe (Na < 120 mEq/L) hyponatremia, and is most frequently observed in elderly ICU hospitalized patients. Based on tonicity, hyponatremia may be hypotonic (a decreased concentration of the solute), isotonic, and hypertonic (falsely low so… Show more
