Using magnesium to protect the brain after cardiac arrest

Neuroprotection Following Cardiac Arrest: A Randomized Control Trial of Magnesium

PHASE1 · NYU Langone Health · NCT06455514

What this trial studies

This pilot interventional study aims to evaluate the safety and feasibility of administering magnesium sulfate as a neuroprotective treatment in patients who have achieved Return of Spontaneous Circulation (ROSC) following cardiac arrest. The study will measure serum markers of neuronal injury at specific time points after ROSC to gather preliminary data. With a limited sample size, the primary goal is to assess the precision and stability of these measures to inform future larger trials.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 who have achieved ROSC within 2 hours of cardiac arrest.

Not a fit: Patients with traumatic cardiac arrests or those who are expected to have life support withdrawn within 72 hours may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve neurological outcomes for patients who survive cardiac arrest.

How similar studies have performed: While this approach is novel, similar studies exploring neuroprotection after cardiac arrest have shown promise, indicating potential for success.
