Using hydrocortisone and vasopressin to improve outcomes after cardiac arrest

HYdrocortisone and VAsopressin in Post-REsuscitation Syndrome

Phase 3 Interventional Assistance Publique - Hôpitaux de Paris · NCT04591990

This study is testing if using hydrocortisone and vasopressin can help improve survival and brain recovery in adults who have had a cardiac arrest and are struggling with serious health issues afterward.

What this trial studies

This clinical trial aims to evaluate the effectiveness of arginine-vasopressin (AVP) and hydrocortisone compared to norepinephrine in improving survival and neurological recovery in patients who have experienced cardiac arrest and subsequent hemodynamic failure. The study will involve adult patients who have been successfully resuscitated and are experiencing post-resuscitation syndrome, characterized by multiple organ failures and hemodynamic instability. Participants will be randomly assigned to receive either AVP, hydrocortisone, a placebo for AVP, or a placebo for hydrocortisone, with the goal of assessing the impact on day-30 survival rates and neurological outcomes. The trial will be conducted in multiple intensive care units across various locations.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have experienced cardiac arrest and have been resuscitated but are still in shock requiring vasopressor support.

Not a fit: Patients with traumatic or neurological causes of cardiac arrest, uncontrolled hemorrhage, or those with known adrenal insufficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment approach could significantly improve survival rates and neurological recovery for patients after cardiac arrest.

How similar studies have performed: Other studies have explored hormonal therapies in similar contexts, but this specific combination of AVP and hydrocortisone in post-resuscitation syndrome is relatively novel.
