What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether placing a balloon in the main artery (aorta) during CPR helps restart the heart more often than standard CPR alone. The balloon is inserted through the leg and inflated to block blood flow below the chest, potentially sending more blood to the heart and brain. Researchers are recruiting 98 adults who suffer cardiac arrest in the hospital.

What this could mean

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

Active substance
balloon catheter (REBOA) placed in the aorta
What this could lead to
If it works, this could provide a new way to improve blood flow during CPR, potentially increasing survival after cardiac arrest.
What could go wrong
This is a relatively small, early-stage trial, so results may not be conclusive. The balloon procedure itself carries risks like vessel damage or bleeding.

Study facts

What this study's own registry entry says, in plain language.

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.

Participants

About 98 people

The number the study aims to enrol. It can still change while the study runs.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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: * patients suffering from in hospital cardiac arrest (IHCA), including patients with out of hospital cardiac arrest (OHCA) and return of spontaneous circulation (ROSC), transported to the emergency department, where they suffer a second arrest (IHCA) * successful placement of a femoral artery introducer sheath * any electrical cardiac activity seen in the initial rhythm analysis * ongoing effort of resuscitation as determined by study-independent resuscitation lead Exclusion criteria: * IHCA in the operating room, on intensive care unit or in the cardiac catheter laboratory * hospital visitors suffering from cardiac arrest * asystole seen in the initial rhythm analysis * (presumed) age under 18 years * known "do not resuscitate"-order * known or obvious pregnancy * traumatic cardiac arrest * known aortic pathologies that render cannulation impossible * known allergies to radiographic contrast agents
