Hyponatremia | Establishment of an Algorithm for a Clinical Classfication of Hypoosmolar Hyponatremia

Hyponatremia research study

What is the primary objective of this study?

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.

Who is eligible to participate?

Inclusion Criteria: - hypoosmolar hyponatremia with serum sodium concentration ≤129 mmol/l and serum osmolality ≤ 280 mosm/kg; - age > 18 years; - letter of agreement. Exclusion Criteria: - gravidity and lactation; - restricted decision-making-ability

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?


Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
