NCT ID NCT07013734

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 observational study looks at whether changing a patient's body position during surgery affects brain monitoring values in people under general anesthesia. Researchers will track brain activity, pain response, and brain oxygen levels while briefly moving the operating table into two positions. The goal is to see if these position changes alter the monitor readings, which could help improve how anesthesia depth is measured. Participants will also answer a short questionnaire about their memories before and after anesthesia.

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 positioning affects these monitors, it could lead to more accurate anesthesia monitoring and better patient safety during surgery.
What could go wrong
This is a small observational study, so it may not capture all factors. Results may not apply to all patients or surgeries, and the monitors' readings could vary for other reasons.
