What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 lung ultrasound can accurately confirm the position of a double-lumen breathing tube used in lung surgery. Researchers will compare ultrasound results with the standard method (fiberoptic bronchoscopy) and simple listening (auscultation) in 100 adults undergoing planned lung surgery. If ultrasound proves reliable, it could offer a faster, noninvasive alternative for checking tube placement.

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 lung ultrasound is a reliable, quick, and noninvasive way to check breathing tube placement during lung surgery.
What could go wrong
This is a small observational study, not a treatment trial. Ultrasound may not be as accurate as the gold standard, and results may not apply to all patients or settings.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients aged 18-65 years undergoing elective thoracic surgery requiring one-lung ventilation with a double-lumen endobronchial tube at Izmir City Hospital will be included in this study. Patients will be recruited consecutively after providing written informed consent. The position of the double-lumen tube will be evaluated using auscultation and lung ultrasonography and confirmed by fiberoptic bronchoscopy as part of routine clinical practice.

Ages
