Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 21 to 79 who are comatose following a return of spontaneous circulation after cardiac arrest.
✕Probably not a fit
Patients aged 80 and older, pregnant individuals, or those with limitations on care may not benefit from this study.

What this trial studies
This proof of concept study evaluates an individualized blood pressure management strategy aimed at enhancing cerebral blood flow in patients who have experienced out-of-hospital cardiac arrest. The approach involves using advanced monitoring techniques, including transcranial Doppler ultrasound and near-infrared spectroscopy, to tailor blood pressure targets for each patient. The effectiveness of this strategy will be assessed by measuring levels of neuron-specific enolase, a biomarker for brain injury, at baseline and 72 hours post-intervention. The study aims to recruit 49 patients to determine if this personalized approach can reduce brain injury compared to standard care.
Why it matters
Potential benefit: If successful, this study could lead to improved brain recovery and outcomes for patients who suffer cardiac arrest.
How similar studies have gone: While this approach is innovative, similar studies targeting cerebral perfusion have shown promise, but this specific strategy is relatively novel.
