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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

After a cardiac arrest, many patients remain comatose and are at risk of further brain injury. Doctors currently measure brain oxygen by drawing blood from the jugular vein and sending it to a lab, which takes time. This study tests a special catheter that can measure oxygen levels continuously, right at the bedside. Researchers will enroll 25 comatose patients to see if the new method is accurate compared to standard lab tests.

What this could mean

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

Active substance
PediaSat Oximetry Catheter (device)
What this could lead to
If accurate, this catheter could give doctors real-time brain oxygen data, helping them detect and treat secondary brain injury faster in comatose patients after cardiac arrest.
What could go wrong
This is a small, early feasibility study with only 25 participants at one hospital. The catheter may not prove accurate enough, and results may not apply to all patients.

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: • Adults (\>=18 years old) resuscitated from out-of-hospital or in-hospital cardiac arrest who remain comatose (motor Glasgow coma scale \<=4) for at least 30 minutes when examined off sedation/neuromuscular blockade. Exclusion Criteria: * Cardiac arrest due to traumatic brain injury, intracranial bleeding, or ischemic stroke * Cervical spine fracture * Need for immediate prone positioning for severe hypoxemic respiratory failure * Marked hemodynamic instability precluding priority of any neuromonitoring (multiple recurrent cardiac arrests, norepinephrine equivalents \> 1.5 mcg/kg/min) * Moribund neurological status based upon initial clinical, radiographic and historical assessment (e.g. diffuse cerebral edema or herniation on head computed tomography) * Pregnancy * Prisoners
