PYZOCHA, DO, Madigan Army Medical Center, Tacoma, Washington Am Fam Physician. Hyponatremia and hypernatremia are common findings in the inpatient and outpatient settings. Sodium disorders are associated with an increased risk of morbidity and mortality. Plasma osmolality plays a critical role in the pathophysiology and treatment of sodium disorders. Hyponatremia and hypernatremia are classified based on volume status (hypovolemia, euvolemia, and hypervolemia). Sodium disorders are diagnosed by findings from the history, physical examination, laboratory studies, and evaluation of volume status. , which increases following the administration of oral salt. We analyze the use of an oral salt load followed by furosemide for the acute/short-term treatment of euvolemic SIADH hyponatremia. Methods: Retrospective analysis of nine patients with SIADH-induced hyponatremia and moderate hyponatremic encephalopathy receiving 45 g of oral salt, followed 3 h later by 20 mg furosemide i.v. Serum sodium levels (SNa), serum potassium (SK), and urinary sodium (UNa) were measured at baseline, and 1216 h following salt administration. All blood pressure levels were below 130/85 mm Hg before and after salt administration. In six out of nine patients, a SNa level was available from 24 h or less previously (PSNa). Conclusions: The oral administration of 45 g of salt followed by furosemide was useful for the acute/short-term treatment of euvolemic SIADH-hyponatremia in our patients. However, this therapy should not be attempted in severe hyponatremia, since a minimum 4 mmol/l SNa rise was not assured.
This video explains why thiazide diuretics are more likely to cause hyponatremia than loop diuretics. Plasma sodium concentration is a ratio of. Doctors give unbiased, trusted information on whether Furosemide can cause or treat Low Sodium Dr. Legha on lasix and hyponatremia Lasix furosemide causes sodium wasting, so it classically causes a hyponatremia.
