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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 observational study is testing whether non-invasive monitors that track brain electrical activity and oxygen levels can help determine the best blood pressure to maintain during major non-cardiac surgery in people over 60. The goal is to see if these monitors can reliably guide blood pressure management to protect brain health and reduce the risk of postoperative delirium. Participants will wear forehead sensors before, during, and after surgery, and complete daily thinking and memory questionnaires.

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 study could help doctors set personalized blood pressure targets during surgery to reduce the risk of postoperative delirium and cognitive decline.
What could go wrong
This is a small observational study (100 participants) that only monitors data without changing care, so it cannot prove that tailored blood pressure improves outcomes. Results may not apply to all 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

Patients above the age of 60 scheduled to undergo major non-cardiac surgeries including but not limited to vascular, hepatobiliary, or complex spine surgeries requiring general anesthesia with arterial catheterization for monitoring.

Ages

60 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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: * Age ≥ 60 years * Undergoing any non-cardiac surgeries including but not limited to vascular, hepatobiliary, or complex spine surgeries requiring general anesthesia with arterial catheterization for monitoring Exclusion Criteria: 1. Non-English speaking (Justification: cognitive assessment instruments are not validated in a sufficient range of languages, and the research team lacks polylingual capabilities or the financial resources to hire interpreters for the duration of all proposed assessments.) 2. Cognitive impairment as defined by total MoCA score \< 10 (justification: baseline cognitive dysfunction will confound primary outcome measure) 3. Significant visual impairment (justification: will be difficult for patients to draw individual components in MOCA score) 4. Emergent surgery (justification: insufficient time to initiate intervention) 5. History of stroke within the last 3 months (justification: cognitive dysfunction secondary to stroke can confound outcome measures
