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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tracks 120 adults having heart surgery to see if continuous monitoring of blood pressure and brain oxygen levels can predict problems like confusion, memory loss, or kidney injury afterward. Researchers will measure how long and how severely these levels drop during surgery. No extra treatments are given—just standard care. The goal is to find better ways to spot high-risk patients early.

What this could mean

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

What this could lead to
If successful, this could help doctors identify patients at higher risk for brain or kidney problems after heart surgery, allowing for earlier, personalized care.
What could go wrong
This is an observational study, not a treatment trial. It may find no strong link between the monitoring measures and outcomes, or the results may not apply to all heart surgery patients.

Who can take part

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

Who is studied

Adult patients (≥18 years) undergoing cardiac surgery, with or without cardiopulmonary bypass. Patients must provide written informed consent, have a preoperative Glasgow Coma Scale score of 15, no history of dementia or cognitive impairment, and be oriented and cooperative prior to surgery. Continuous intraoperative monitoring of mean arterial pressure (MAP) and cerebral regional oxygen saturation (rSO₂) is performed. Emergency surgeries and patients with pre-existing cognitive impairment are excluded.

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.
