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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a detailed, color-coded brain wave monitor (Density Spectral Array) helps anesthesiologists use less medication compared to a standard single-number monitor (Bispectral Index). 45 adults undergoing gynecological cancer surgery were observed. The goal was to see if the newer monitor leads to more personalized anesthesia and pain relief, potentially reducing drug amounts and improving recovery.

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 show that a more detailed brain monitor helps anesthesiologists use less medication, potentially leading to faster recovery after surgery.
What could go wrong
This is a small, completed observational study with only 45 participants. Results may not apply to other surgeries or patient groups, and the benefit over standard monitoring may be minimal.

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 female patients aged 18-65 years, with an ASA physical status of I-III, who are scheduled for elective gynecological oncology surgery under general anesthesia at a single tertiary oncology center. Participants are selected from patients who meet the inclusion criteria and do not require premedication, ensuring a standardized group for monitoring anesthesia depth and drug consumption.

Ages

18 to 65 years

Sex
