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
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 This study
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 Results may not be published yet.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.

Summary

This completed trial tested a new multi-modal monitoring system that combines EEG, brain oxygen levels, blood pressure, and heart rate to better measure anesthesia depth. Researchers enrolled 330 patients undergoing non-cardiac surgery under general anesthesia. The goal was to see if the system could accurately detect when anesthesia is too deep or too shallow, potentially improving patient safety.

What this could mean

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

Active substance
Multi-modal Intelligent Anesthesia Monitoring System
What this could lead to
If successful, this system could help anesthesiologists more accurately monitor how deep a patient is under anesthesia, reducing risks of awareness or overdose.
What could go wrong
This is a device development study, not a treatment trial. It may not outperform existing monitors or work well across all patient types.
