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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares lung ultrasound performed by medical trainees to standard chest X-rays for detecting pneumothorax (collapsed lung) after chest tube removal in heart surgery and trauma patients. Researchers will enroll 60 adults to see if the ultrasound method is accurate and practical. If it works, it could offer a safer, faster, and less painful way to diagnose this serious condition.

What this could mean

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

Active substance
lung ultrasound
What this could lead to
If successful, this could show that lung ultrasound performed by trainees is a reliable, safer, and less painful alternative to chest X-rays for detecting pneumothorax after chest tube removal.
What could go wrong
This is a small pilot study (60 participants) focused on feasibility, not yet proving accuracy. Results may not apply to all patients or settings, and novice operators may miss signs.

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

About 60 people

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

Started

Sep 2023

Expected to finish

Dec 2025

An estimate. End dates often move.

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

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: * Age ≥ 18 years old. * Cardiac and trauma patients who have had a chest/mediastinal tube removed within the past two hours in the CVICU, trauma bay, or ward. Exclusion Criteria: * Patients who had a PNX prior to mediastinal chest tube removal that required intervention. * Patients on mechanical ventilation. * Patients with subcutaneous emphysema due to impaired pleural line visualization.
