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 Results may not be published yet.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.

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 wave patterns, measured by EEG, can help explain why some children become confused and agitated after waking up from anesthesia (emergence delirium). Researchers will monitor children aged 2 to 8 who are having eye surgery under general anesthesia. They will measure the children's anxiety before surgery, their brain wave activity during surgery, and their level of confusion after waking up. The goal is to see if brain wave patterns link pre-surgery anxiety to post-surgery confusion.

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 identify children at risk for emergence delirium before they wake up from anesthesia.
What could go wrong
This is an observational study with 80 children, so results may not apply to all pediatric surgeries or age groups.
