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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study watches 126 adults having gallbladder surgery to see if ups and downs in anesthesia depth (measured by BIS) relate to how well they recover. Patients fill out a recovery questionnaire before and after surgery. No extra treatments are given—just standard care. The goal is to learn whether keeping anesthesia more stable could help people feel better sooner.

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 adjust anesthesia to improve patient recovery after surgery.
What could go wrong
This is a small observational study, not a treatment trial. It only looks for a link, not a cause, and results may not apply to other surgeries or patients.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients aged 18 to 65 years undergoing elective laparoscopic cholecystectomy under general anesthesia. All participants will receive routine perioperative care according to standard clinical practice, including intraoperative bispectral index (BIS) monitoring. The study includes a single prospective observational cohort, and no experimental intervention or alteration of standard anesthesia management will be performed. Participants will be assessed preoperatively and postoperatively to evaluate changes in recovery quality following surgery.
