What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether starting ECMO (a heart-lung bypass machine) right at the location of a cardiac arrest, rather than waiting until the patient reaches the hospital, could improve survival with good brain function. Researchers enrolled 65 adults with refractory cardiac arrest. The goal was to see if early ECMO could raise survival from around 5% to 20%.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ECMO (extracorporeal membrane oxygenation)
What this could lead to
If pre-hospital ECMO works better, it could significantly increase survival rates for people who suffer a cardiac arrest outside the hospital.
What could go wrong
This is a small, completed study with only 65 participants, so results may not apply broadly. ECMO carries risks like bleeding and infection, and the benefit over standard care is not yet proven.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Eligible patients have the following combination of criteria: * Adults over 18 years of age and under 65 years of age * And Refractory cardiac arrest (defined by the failure of professionals to resuscitate at the 20th minute of cardiac arrest with a minimum of 3 Automatic External Defibrillator (AED) or equivalent analyze * And Beginning of external cardiac massage within the first 5 minutes after cardiac arrest (no flow \< 5 min.) with shockable rhythm or the presence of signs of life during resuscitation (any rhythm): spontaneous movement, absence of mydriasis and/or pupillary response, spontaneous breathing movements * And Medical cause of the cardiac arrest * And End-Tidal CO2 (ETCO2) above 10 mm Hg at the time of inclusion * And Absence of major co-morbidity. And Extra-corporeal Membrane Oxygenation (ECMO) team available and on-site before the 40th minute Exclusion Criteria: * Children under 18 years of age * Adults over 65 years of age * Period of more than 5 minutes without cardiac massage after collapsing * Known co-morbidity that compromises the prognosis for short or medium-term survival * Cardiac arrest during transportation times
