Using Angiotensin II to Treat Vasoplegic Shock

Angiotensin II Stress Test. Renin Kinetics During Treatment of Vasoplegic Shock With Angiotensin II in Relation to Hemodynamic Response to Treatment With Angiotensin II.

Observational University Medical Centre Maribor · NCT06539234

This study is testing if giving angiotensin II can help adults with a specific type of shock improve their blood pressure and reduce the time they spend in the ICU.

What this trial studies

This observational study investigates the effects of angiotensin II infusion in patients experiencing distributive shock who have not achieved adequate blood pressure despite receiving other vasopressors. Patients aged 18 and older with a specific type of shock will receive an angiotensin II infusion, and blood samples will be collected before and after treatment to measure renin levels. The primary focus is on the number of days free from organ failure and ICU stay, while secondary outcomes include the need for additional vasopressors and other interventions. The study aims to better understand the role of renin in shock severity and the effectiveness of angiotensin II in managing blood pressure.

Who should consider this trial

Good fit: Ideal candidates are adults with distributive shock lasting less than 72 hours who have not responded to standard vasopressor treatments.

Not a fit: Patients with severe comorbid conditions such as acute coronary syndrome or significant liver disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve blood pressure management in patients with vasoplegic shock and reduce the incidence of complications.

How similar studies have performed: Previous studies have indicated that angiotensin II can be effective in managing shock, suggesting potential success for this approach.
