Active removal of brain hemorrhage using irrigation

Active Removal of IntraCerebral Hematoma Via Active Irrigation of the Ventricular System

NA · IRRAS · NCT05118997

This study is testing if a new method using the IRRAflow® system can help clear brain bleeding faster and improve recovery for patients with spontaneous intracerebral hemorrhage compared to standard treatments.

What this trial studies

This study evaluates the effectiveness of active irrigation using the IRRAflow® system combined with tPA infusion in clearing intracerebral and intraventricular hemorrhage compared to traditional passive drainage methods. It is a multicenter, randomized, controlled trial that aims to determine if this innovative approach can improve neurological outcomes for patients suffering from spontaneous intracerebral hemorrhage. The primary focus is on reducing the time required for hemorrhage clearance and assessing patient recovery through established neurological scales.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who require external ventricular drainage for spontaneous intracerebral hemorrhage.

Not a fit: Patients under 18 years old, those without a need for external ventricular drainage, or those with severe coagulopathy or fixed and dilated pupils may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to faster recovery and improved neurological outcomes for patients with brain hemorrhages.

How similar studies have performed: Other studies have explored similar interventions, but this specific approach using active irrigation with IRRAflow® is relatively novel.
