NCT ID NCT07596446

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 Results may not be published yet.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

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

Summary

This study tests whether paramedics can safely place a small tube in the leg artery of people having a cardiac arrest outside the hospital. The tube allows continuous blood pressure monitoring, which may help doctors give the right amount of medication to keep the heart pumping. The goal is to see if this approach is feasible and safe, and whether it can prevent another cardiac arrest during transport.

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

Inclusion Criteria: \* Non-traumatic out-of-hospital cardiac arrest (OHCA). Patients meeting criteria for one of the following clinical scenarios: Group A - ECPR-like group: * Refractory cardiac arrest, including cardiac arrest occurring in the presence of the EMS crew. * Age 18-70 years. * Effective bystander cardiopulmonary resuscitation. * Initial rhythm of ventricular fibrillation (VF), pulseless ventricular tachycardia (pVT), or pulseless electrical activity (PEA). Group B - post-ROSC group: * Return of spontaneous circulation (ROSC) after non-traumatic OHCA. * Age 18-70 years. Exclusion Criteria: * Trauma as the probable primary cause of cardiac arrest. * Known severe comorbidity, including: * terminal stage of incurable disease (advanced malignancy, advanced dementia, terminal pulmonary disease, terminal heart failure, or palliative care status), * established do-not-resuscitate (DNR) status, * severe pre-existing neurological disability (CPC 3 or CPC 4), * known severe peripheral arterial disease or known occlusion of lower limb arteries, * suspected pulmonary embolism with indication for thrombolytic therapy, * known severe hematological disease associated with severe thrombocytopenia, * morbid obesity. * Known or suspected pregnancy.
