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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a pulse oximeter placed in the throat (oropharynx) can accurately measure blood oxygen levels during surgery. Researchers compared readings from the throat sensor to standard finger or toe sensors and to blood tests. The goal was to see if this new approach is feasible for patients who cannot use traditional sensors.

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 provide a new way to monitor oxygen levels in patients where standard finger or toe sensors cannot be used.
What could go wrong
This is a small feasibility study, not a large trial. The new method may not be as accurate or reliable as standard pulse oximetry, and it may not work for all patients.

Study facts

What this study's own registry entry says, in plain language.

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

100 people

The number who actually took part.

Started

Jan 2024

Finished

Jan 2025

Lead sponsor

Other sponsor

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.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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

Inclusion Criteria: * Patients undergoing a surgical procedure with general anesthesia and requiring an invasive arterial cannula Exclusion Criteria: * Patients in whom an arterial cannula is not indicated for the surgical procedure * Patients in whom a peripheral pulse oximeter value cannot be obtained * Patients in whom an invasive arterial cannula cannot be placed * Patients with any type of intra-oral pathology or injury * Patients in whom access to the oropharynx is restricted or not feasible for any clinical reason
