The prospective clinical diagnosis of hyponatremia is often very difficult- but requirement for an appropriate and riskless treatment of hyponatremia. This study try to establish an algorithm handling a prospective clinical categorization of hyponatremia and approving together the start of an appropriate symptomatic therapy.
