Feasibility Study of Novice-Performed Lung Ultrasound for Pneumothorax Detection After Cardiac Surgery
Canada120 participantsStarted 2025-09-16
Plain-language summary
What is the purpose of this study? This study is being done to find out if medical trainees (such as residents and fellows) can learn to use lung ultrasound to detect a collapsed lung (pneumothorax) after heart surgery.
Who is participating in the study? Adults who have recently had heart surgery and are having their chest tubes removed in the intensive care unit may be able to join.
What will happen during the study? After chest tubes are removed, a trained medical trainee will use a small ultrasound device to check the lungs at the bedside. The patient will also have a chest X-ray, which is the usual test. The results from the ultrasound will be compared to the chest X-ray and reviewed by expert doctors.
What is the goal of the study? The goal is to see if it is possible to train medical trainees to use lung ultrasound safely and accurately in real hospital settings. The results will help plan a larger study in the future.

Inclusion Criteria:
* Age 18 years or older
* Undergoing cardiac surgery
* Scheduled for chest and/or mediastinal chest tube removal in the cardiovascular intensive care unit (CVICU)
Exclusion Criteria:
* Severe chronic lung disease that may impair lung ultrasound interpretation, including:
* Subcutaneous emphysema
* COPD or emphysema with FEV₁ \< 50% predicted
* Interstitial lung disease with FEV₁ \< 75% predicted
* Documented history of pneumothorax prior to chest tube removal requiring intervention
* Mechanical ventilation at the time of eligibility screening
* Inability to undergo lung ultrasound or chest X-ray (e.g., due to hemodynamic instability or positioning limitations)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
