What this Trial Is About
This research focuses on patients who are considered for extracorporeal cardiopulmonary resuscitation (eCPR), a rescue treatment using extracorporeal membrane oxygenation (ECMO) to support the heart and lungs during cardiac arrest. The study aims to explore whether it is possible to perform neuroprognostication very early, even before ECMO starts, using automated pupillometry and cerebral near-infrared spectroscopy (cNIRS). This could help improve patient selection and predict neurological outcomes sooner than current guidelines recommending assessments 72 hours after cardiac arrest. Participants will have their pupils assessed with an automated pupillometry device and their brain oxygen levels monitored using a cerebral near-infrared spectroscopy system. These measurements will be taken before ECMO initiation, shortly after ECMO starts at several intervals within the first three hours, and during follow-up at 24, 48, and 72 hours after ECMO initiation. The study will evaluate the feasibility of these early assessments and collect data to analyze neurological outcomes and survival at 1, 6, and 12 months. During the study, patients will undergo repeated non-invasive monitoring using these diagnostic tests without affecting their clinical treatment. Researchers will record and interpret the measurements to determine the reliability and usefulness of early neuroprognostication. The study will monitor neurological outcome and mortality over time to understand the potential predictive value of these early assessments. Participation duration varies with the follow-up period extending up to one year after treatment.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Patients 18 years or older evaluated for eCPR treatment at the Department of Emergency Medicine
You will not qualify if you...
- Return of spontaneous circulation before ECMO initiation
- Severe facial trauma or deformity preventing use of automated pupillometry device
- Scalp injuries, dressings, or conditions interfering with near-infrared spectroscopy sensor placement
- Pre-existing eye conditions preventing reliable pupillometry such as enucleation, opaque cornea, or severe anisocoria unrelated to neurological status
