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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 observational study tests a spectroscopic sensor that measures oxygen levels in muscle tissue during vascular surgery. It aims to see if the sensor can detect changes in oxygenation when blood flow is temporarily blocked and then restored. The study involves 30 adults undergoing peripheral arterial bypass surgery. The goal is to understand if this technology could help surgeons monitor tissue health in real time.

What this could mean

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

Active substance
SpectroCor Monitoring System (spectroscopic sensor)
What this could lead to
If successful, this could lead to better real-time monitoring of tissue oxygenation during surgery, potentially reducing complications from ischemia.
What could go wrong
This is a small observational study, so results may not apply broadly. The sensor's accuracy and clinical benefit remain unproven.
