Treating the syndrome of inappropriate ADH secretion with isotonic saline. The treatment of hyponatremia: Utility and limitations of biochemical parameters in the evaluation of hyponatremia in the elderly.

J Clin Pathol ; N Engl J Med ; Crit Care Med ; Clin Chim Acta ; The Clinical Problem Hyponatremia, defined as an excess of water in relation to the sodium in the extracellular fluid, is the most common electrolyte disorder in hospitalized patients.

Mild chronic hyponatremia is associated with falls, unsteadiness, and attention deficits.

Am Heart J ; Loop diuretics also increase the rate of increase in the serum sodium level. Int Urol Nephrol ; J Am Soc Nephrol ; Successful long-term treatment of hyponatremia in syndrome of inappropriate antidiuretic hormone secretion with SR B, an orally active, nonpeptide, vasopressin V-2 receptor antagonist.

One theoretical concern is that vasopressin-receptor antagonists might increase serum sodium levels too rapidly, putting patients at risk for osmotic demyelination. Ann Intern Med ; In the absence of symptoms, gradual correction of the hyponatremia is appropriate and should involve adequate solute intake including salt and protein and fluid restriction, starting at ml per day of water on the basis of the formula shown in Figure 2.


A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone. Her thyroid function and adrenal function were normal. Incidence and prevalence of hyponatremia. A year-old woman noted an unpleasant, sweet taste in her mouth. Myelinolysis after correction of hyponatremia.

In a double-blind, hyponatremoa trial, in patients assigned to conivaptan for 4 days, yyponatremia compared with those assigned to placebo, the serum sodium levels increased by 6 mmol per liter. Vasopressin-Receptor Antagonist Therapy A more recent option for treating SIAD is conivaptan Vaprisol, Astellas Pharmaa vasopressin-receptor antagonist approved by the Food and Drug Administration in for intravenous treatment of euvolemic hyponatremia 34 and approved in for intravenous treatment of hypervolemic hyponatremia 35 Table 3.


The incidence and pathophysiology of hyponatraemia after subarachnoid haemorrhage.

NEJM — The Syndrome of Inappropriate Antidiuresis

J Clin Endocrinol Metab ; Measurement of the serum level of arginine vasopressin is not recommended routinely, because urinary osmolality above mOsm per kilogram of water is usually sufficient to indicate excess of circulating arginine vasopressin. Acid-base and electrolyte disorders: Therapeutic approach in patients with dysnatraemias.

Hypouricemia in the syndrome of inappropriate secretion of antidiuretic hormone.

Prevention of hospital-acquired hyponatremia: Other formulas incorporate amounts of salt and water infused and excreted 3940 ; these add precision, but at the price of complexity.

The rate of change in serum sodium levels must be monitored every 2 to 3 hours, and the infusion adjusted as needed. Current prescriptions for the correction of hyponatraemia and hypernatraemia: Initial reports suggested that secretion of arginine vasopressin hyponatreemia SIADH was independent of plasma osmolality.
