Understanding brain injury after cardiac arrest

Delineating Between Pathophysiologic Phenotypes of Hypoxic Ischemic Brain Injury After Cardiac Arrest

NA · University of British Columbia · NCT05390060

This study is trying to see if different types of brain injuries after cardiac arrest affect how well oxygen gets to the brain, to help improve care for patients.

What this trial studies

This study aims to differentiate between two types of hypoxic ischemic brain injury (HIBI) in patients who have experienced cardiac arrest. It will evaluate patients' oxygen transport dynamics to determine if they exhibit normal or impaired oxygen delivery to the brain. The research will involve neuromonitoring and various assessments to explore the underlying mechanisms of oxygen transport limitations and their impact on clinical outcomes. By identifying these differences, the study seeks to improve management strategies for post-cardiac arrest patients.

Who should consider this trial

Good fit: Ideal candidates are adults over 19 years old who have experienced cardiac arrest and have a Glasgow Coma Scale score of 8 or less.

Not a fit: Patients with coagulopathy, severe traumatic brain injury, or those currently on anticoagulant medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better-targeted treatments for patients suffering from brain injuries after cardiac arrest.

How similar studies have performed: While there have been studies on hypoxic ischemic brain injury, this approach of differentiating between oxygen transport dynamics is novel and has not been extensively tested.
