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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 repeatedly inflating and deflating a blood pressure cuff on a leg can reduce brain damage in people who survive a cardiac arrest outside the hospital. The procedure, called remote ischemic post-conditioning (RIPOST), is started within 4 hours after the heart restarts. Researchers will measure brain injury markers in the blood and organ failure scores in 48 adults in the ICU. The goal is to see if this simple, non-drug approach improves neurological outcomes.

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

Inclusion Criteria: * Out-of-hospital cardiac arrest with stable return of spontaneous circulation (ROSC \> 20 minutes) * Patient receiving invasive mechanical ventilation for coma (Glasgow score \< 8) * Availability of a lower limb without intravenous infusion or tension cuff positioned on it * Randomization and application of the first session of the tested procedure within 4 hours after ROSC * Consent of a next-of-kin or inclusion in emergency procedure Exclusion criteria : * Age \< 18 y.o or pregnancy * Patient unable to walk without assistance, unable to support himself properly without assistance, bedridden, incontinent and requiring nursing constant attention and care (corresponding to a mRS equal to 4 or 5) * Interval between cardiac arrest and ROSC (no flow + low flow) estimated \> 60 minutes * Unwitnessed cardiac arrest with asystole as first rhythm * In-hospital cardiac arrest * Refractory cardiac arrest (no ROSC considered as stable) * Cardiac arrest from traumatic, hemorrhage, stroke or hanging supposed origin * Mean arterial pressure \< 65mmHg persisting despite appropriate vascular filling and vasopressor and/or inotropic support * Active uncontrolled bleeding * Contraindication or not possible to use a pneumatic tourniquet on none of the two lower limbs (amputations, intravenous infusion positioned on both lower limbs, tourniquet size incompatible with patient morphology) * Implementation of extracorporeal arteriovenous circulation for refractory cardiac arrest or refractory cardiogenic shock before inclusion * Patient already included in this study * Inclusion in another interventional study which purpose is to improve prognosis after a cardiac arrest * Judicial protection measure * Patient without French social security
