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 Results may not be published yet.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.

Summary

This study looks at whether brain activity measured before surgery can predict how much propofol (a common anesthesia drug) a person needs to reach deep anesthesia. Researchers will test 110 adults with cognitive tests and EEG scans before their operation. The goal is to make anesthesia dosing more personalized and safer.

What this could mean

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

Active substance
propofol
What this could lead to
If successful, this could help doctors tailor anesthesia doses to each patient, reducing risks and improving safety during surgery.
What could go wrong
This is a small observational study, not a treatment trial. It may not lead to a practical tool, and individual responses to anesthesia vary widely.
