The Syndrome of Inappropriate Antidiuresis. Antagonize action of ADH in the kidney. Mild chronic hyponatremia is associated with falls, unsteadiness, and attention deficits.

When symptoms of osmotic demyelination develop during the treatment of hyponatremia, case reports suggest that it may be possible to reverse the neurologic deficits by again lowering the serum sodium level. J Clin Pathol ; Most cases of hyponatremia that occur out of the hospital are chronic and minimally symptomatic, except in marathon runners, users of 3,4-methylenedioxymethamphetamine MDMA, also known as “ecstasy”and people who drink water to excess; in these groups, severe symptoms usually indicate acute hyponatremia and require rapid correction.

Int Urol Nephrol ; Dialysis patients hyponatremic predialysis.

Currently, conivaptan use is limited to the treatment of hospitalized patients; it might be considered particularly for those who have moderate-to-severe hyponatremia and symptoms but not seizures, delirium, or coma, which would warrant the use of hypertonic saline.

The traditional approach is to estimate a sodium deficit and is not physiologically based, because SIAD is characterized by a water excess, rather than a sodium deficit.

Although hyponafremia is the case in about one third of patients with SIADH 7 Figure 1in other patients with this condition, secretion of byponatremia vasopressin is fully suppressed, resulting in dilute urine, but at a serum sodium level lower than normal a “reset osmostat”.

Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they exist.

Should be done in ICU. Listeners will recall the pathophysiology of hyponatremia and develop a systematized approach to identifying the type and cause of hyponatremia, as well as how to safely manage hyponatremia.


J Am Soc Nephrol ;8: Therapeutic approach in patients with dysnatraemias.

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.

Current prescriptions for the correction of hyponatraemia and hypernatraemia: Causes and management of hyponatremia. Released if hypovolemia, or elevated plasma osmolality.


One theoretical concern hyponstremia that vasopressin-receptor antagonists might increase serum sodium levels too rapidly, putting patients at risk for osmotic demyelination. Summary and Recommendations The patient described in the vignette apparently has chronic hyponatremia attributable to SIAD; she has no neurologic symptoms. Average person with normal renal function must drink more than 18L per day to drop sodium, or more than 2L in an hour e.

Physical exam can help for grossly hypo- or hypervolemic patients, but euvolemia can be difficult to differentiate from mild hypovolemia, or hypervolemia.
