About this study
Official title: Ultrasound-guided Subclavian Venous Catheterization. A Randomized, Single-blind, Controlled Superiority Trial Comparing Standard Ultrasound Guidance and a New Needle-steering Device
Up to two-thirds of intensive care unit patients require central venous catheterization for which ultrasound-guided placement is now recommended. In this context, the team performed a prospective randomized simulation trial on a mannequin ("reduced torso model"), to compare the standard ultrasound guidance technique with an ultrasound-guided technique assisted by a new needle-steering device. The preliminary results show a statistically significant improvement in subclavian venipuncture (shorter success time, fewer multiple skin punctures, fewer punctures of the posterior wall of the subclavian vein and needle redirection, greater comfort) and argue for a clinical trial to test the performance of this new device in situation with intensive care unit patients.
The hypothesis is that the needle-steering device will result in a better success rate of subclavian venous cannulation, at first puncture, compared with the conventional ultrasound-guided technique.
Read the detailed description
Central venous catheterization is required in up to two-thirds of intensive care unit patients. Ultrasound-guided placement is now recommended over the "blind" technique to decrease the risk of mechanical complications and duration of the procedure. Although the subclavian site is recommended as first-line because of a lower risk of catheter-related infection and thrombosis (than with internal jugular and femoral sites), this approach is underused (< 20% of regular users). There is also a very low use of ultrasound guidance for subclavian catheterization (< 30% of cases), due to technical difficulties such as more complex visualization of the needle.
New magnetic devices theoretically allow better visualization of the needle, a higher success rate and a lower complication rate. In this context, the team performed a prospective randomized simulation trial on a phantom ("reduced torso model"), comparing the standard ultrasound guidance technique with an ultrasound-guided technique assisted by a new needle-steering device in subclavian central venous catheterization (study in progress). The results of this study show a statistically significant improvement in subclavian venipuncture (shorter success time, fewer multiple skin punctures, fewer punctures of the posterior wall of the subclavian vein and needle redirection, greater comfort).
These preliminary results argue for a clinical trial of the practical performance of this new device in intensive care unit patients.
The hypothesis is that the needle-steering device will result in a higher success rate of subclavian venous cannulation at first puncture compared with the conventional ultrasound guidance technique.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Up to two-thirds of intensive care unit patients require central venous catheterization for which ultrasound-guided placement is now recommended.

The preliminary results show a statistically significant improvement in subclavian venipuncture (shorter success time, fewer multiple skin punctures, fewer punctures of the posterior wall of the subclavian vein and needle redirection, greater comfort) and argue for a clinical trial to test the performance of this new device in situation with intensive care unit patients.

Questions about this trial
What is this clinical trial studying?
A study testing Subclavian venipuncture for catheter placement using the needle-steering device in people with Ultrasound Guidance and Central Venous Catheterization, run by Centre Hospitalier Universitaire de Nīmes at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Successful catheter insertion at first skin puncture: Control group (time frame: Day 0). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06050902, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2026.
