Subclavian Vein Ultrasound Guided Cannulation in Adult
France100 participantsStarted 2009-04
Plain-language summary
There is actually two techniques of subclavian vein ultrasonography-guided venous catheterization : the axial and longitudinal approach. Currently, nothing makes it possible to privilege one technique compared to the other. This study aims to determine the best ultrasonography-guided method.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patient requiring the installation of a central venous catheter in subclavian site
* Installation of catheter under general anaesthesia
* Oral consent of the patient
Exclusion Criteria:
* Thrombosis in subclavian vein
* Urgency of central venous catheterization.
* Insertion of central vein catheter other than subclavian
* Insertion of subclavian catheter under loco-regional anaesthesia
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.
1This trial looked at ultrasound-guided subclavian vein cannulation during cardiac surgery — is this the technique your team uses when placing central lines for my procedure, or do you use a different approach?
2Since this study measured how quickly a guidewire could be placed in the vein, does a faster insertion time actually translate to a meaningful safety benefit for me as a cardiac surgery patient?
3The trial is now completed — has your team seen or adopted any findings from studies like this one that changed how you perform central line placement during cardiac surgery?
4Are there specific risks tied to subclavian vein access in cardiac surgery patients that I should understand, regardless of whether ultrasound guidance is used?
5If ultrasound guidance isn't routinely available in your facility for this procedure, what alternative technique would be used for my central line, and how does that affect the risk profile?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
