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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether using a brain function monitor during surgery can help anesthesiologists adjust anesthesia dosing to improve recovery. Researchers will compare recovery speed and side effects in young adults (ages 18-45) having planned surgeries, with half receiving standard care and half using the monitor. The goal is to see if this approach leads to earlier discharge and less nausea, grogginess, or pain after surgery. The study also explores whether men and women respond differently to anesthetics with or without this monitoring.

What this could mean

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

Active substance
Sedline Brain Function Monitor (a device that tracks brain activity during anesthesia to guide anesthetic dosing)
What this could lead to
If effective, this approach could help people wake up from anesthesia faster, with fewer side effects like nausea and grogginess, and possibly reveal sex-based differences in anesthetic response.
What could go wrong
This is a small pilot study, so results may not be definitive. The monitor's guidance might not consistently improve recovery, and individual responses to anesthesia vary widely.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * American Society of Anesthesiology Physical Status Classification Grade of 1(normal, healthy patient) to Grade 3 (patient with severe disease) * Between ages 18-45 years old * Planned surgery duration between 60-240 minutes General-endotracheal-tube-anesthesia or general anesthesia with laryngeal mask airway * Subjects capable of giving informed consent or * Subjects who have an acceptable surrogate capable of giving consent on behalf of the subject * All contraception methods will be allowable for any subject in this study. Participants may opt-out of a pregnancy test if they would prefer to proceed with surgery without one. Pregnant women will not be strictly excluded from this study if they meet all other criteria. Exclusion Criteria: * American Society of Anesthesiology Physical Status Classification Grade of 4,5,6 (diseases that are life threatening or no possibility of survival) * Listed allergies to any commonly used anesthetic agents * History of seizures, as a seizure while using brain monitoring may influence the anesthesia provider in a way that is not aligned with the purpose of this study * Any patient undergoing emergency surgery, as can not be ensured that consent will be able to be properly obtained * Patient refusal to participate in study * Any patient undergoing surgery that would prevent placement of the Sedline monitor leads (for example - surgery on the patient's forehead/scalp) * Patients who receive neuraxial anesthesia or a peripheral nerve block as part of their anesthetic * Patients who are taking gender-affirming hormonal medications, as this can affect the response to anesthetics * The duration of surgery scheduled \<60 minutes
