Predicting outcomes for comatose patients after cardiac arrest

Official title: New Predictive Tool of Awakening in Comatose Patients in the Intensive Care Unit

Run by Assistance Publique - Hôpitaux de Paris · NCT05321459 · Data updated 2026-11-12

This study is trying to see if a new method can help doctors predict how well comatose patients will recover after a cardiac arrest by using different tests and a special algorithm.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old who are admitted to the ICU for coma following cardiac arrest and show persistent coma on day 3.

Probably not a fit

Patients who have a decision to limit resuscitation therapies or those unable to undergo auditory evoked potentials due to specific conditions will not benefit from this study.

What this trial studies

This study evaluates the prognosis of comatose patients following cardiac arrest in the intensive care unit using a multimodal approach. It combines clinical examinations, serum biomarkers, imaging, and electrophysiological tests, including auditory evoked potentials (AEP). A novel algorithm developed from AEP signals generates a probability map to classify patients' neurological prognosis as either good or bad. The goal is to apply this algorithm to a large cohort of patients to improve the accuracy of prognosis predictions at three months post-event.

Why it matters

Potential benefit: If successful, this approach could significantly enhance the ability to predict neurological outcomes in comatose patients, leading to better-informed treatment decisions.

How similar studies have gone: Preliminary studies have shown promise in using similar multimodal approaches for prognosis prediction, but this specific algorithm application is novel.

Inclusion Criteria:

* Age above18 years old
* Patient affiliated to a French Heath Care Insurance
* Admitted in the intensive care unit (ICU) for coma post extra- or intra-hospital cardiac arrest (CA) with shockable or non-shockable rhythm
* Persistent coma on day 3 after post CA, defined by the inability to respond to a verbal command in an appropriate manner (motor Glasgow components ≤ 3) and at the time of neurophysiological recordings (D3-D7 ± week -end).

Exclusion Criteria:

* Decision to limit resuscitation therapies taken by the resuscitation team
* Inability to perform the auditory evoked potentials (AEP) (deafness, skin lesion or any condition preventing to record AEP).
