Receive invasive blood pressure monitoring during emergency cardiac arrest treatment

Receive invasive blood pressure monitoring during emergency cardiac arrest treatment | stella

What is this trial?

The FEMART-1 Pilot Study is testing whether paramedics can safely insert a small arterial catheter (a thin tube placed in an artery in the groin) to continuously monitor blood pressure in patients experiencing life-threatening cardiac arrest. This monitoring could help paramedics give better medications and care during the ambulance ride to the hospital.

When the heart stops, doctors need to know whether blood pressure is adequate to keep the brain and organs alive. Current methods can miss dangerous drops in blood pressure. This trial tests whether real-time invasive monitoring could help paramedics catch and treat blood pressure problems faster, potentially preventing the heart from stopping again and improving brain function after survival.

Do you qualify?

You likely qualify if…

you experienced cardiac arrest outside a hospital that was not caused by trauma
you are between 18 and 70 years old
your heart rhythm was one of three specific abnormal patterns (ventricular fibrillation, pulseless ventricular tachycardia, or pulseless electrical activity)
you either had ongoing chest compressions when paramedics arrived, or your heart restarted on its own

You likely don't qualify if…

you have trauma (injury from an accident) as the cause of your cardiac arrest
you have a terminal illness such as advanced cancer, advanced dementia, or end-stage heart or lung disease
you have a medical order stating you do not want resuscitation (DNR order)
you have severe blockages or known disease in the arteries of your legs
you are severely obese, have severe bleeding disorders, or are pregnant or possibly pregnant

What participation looks like

If you join this study, paramedics will provide you with standard life-saving treatment for cardiac arrest. Half of participants will receive an additional procedure: a small tube placed in an artery in the groin to continuously monitor blood pressure during transport to the hospital. All participants will receive standard hospital care. The study will track your recovery, including heart function and brain outcomes, during your hospital stay.
