What are the Schwartz and Bartter criteria for diagnosing SIADH?
They developed the classic Schwartz and Bartter criteria for diagnosing SIADH, which has not changed. SIADH is characterized by impaired water excretion leading to hyponatremia with hypervolemia or euvolemia. This activity reviews the causes, presentation, and diagnosis of SIADH and highlights the interprofessional team’s role in its management.
Which medications are used to treat SIADH?
Vasopressin receptor antagonists such as conivaptan (IV) or tolvaptan (oral) are also available and approved for severe persistent SIADH. These drugs prevent ADH-mediated free water retention by antagonizing V2 receptors and correct hyponatremia. Tolvaptan is hepatotoxic and should not be given to patients with liver disease.
What are the symptoms of SIADH and sidah?
Additionally, SIDAH causes levels of electrolytes, like sodium, to fall as a result of water retention. A low sodium level or hyponatremia is a major complication of SIADH and is responsible for many of the symptoms of SIADH. Early symptoms may be mild and include cramping, nausea, and vomiting.
