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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 applying pressure to the left side of the neck (left paratracheal pressure) during anesthesia induction changes oxygen levels in the brain. It includes 70 adults undergoing elective surgery with general anesthesia. Each participant will have brain oxygen measured continuously under three conditions: no neck pressure, left paratracheal pressure, and standard cricoid pressure. The goal is to see if this alternative maneuver, which may reduce regurgitation risk, also maintains adequate brain oxygenation.

What this could mean

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

Active substance
Left paratracheal pressure (a manual neck pressure maneuver) compared with cricoid pressure during anesthesia induction
What this could lead to
If left paratracheal pressure proves safe for brain oxygenation, it could become a preferred method to prevent regurgitation during anesthesia, potentially improving patient safety.
What could go wrong
This is a small, early-stage crossover study in 70 patients, so results may not apply broadly. The pressure could still affect brain oxygen in some individuals, and the study only measures short-term effects during anesthesia induction.

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.

Participants

About 70 people

The number the study aims to enrol. It can still change while the study runs.
