Predicting outcomes for comatose patients after cardiac arrest

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

Observational Assistance Publique - Hôpitaux de Paris · NCT05321459

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.

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.

Who should consider this trial

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.

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.

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

Eligibility criteria

Show full inclusion / exclusion criteria
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).
* Opposition by the trusted person or by the patient once he/she wakes up
