Ultrasound device will be used to locate artery for puncture.
Artery puncture without ultrasound guidanceProcedure or surgery
Blood drawn from radial artery according to conventional procedure, without ultrasound guidance.
| Study group | Role | What they receive |
|---|---|---|
| With ultrasound guidance | Experimental | In this group of patients, ultrasound guidance will be used when drawing blood from the radial artery. Receives: Procedure: Artery puncture with ultrasound guidance |
| Without ultrasound guidance | Active comparator | In this group of patients, no ultrasound guidance will be used when drawing blood from the radial artery. Receives: Procedure: Artery puncture without ultrasound guidance |

The primary outcome is the main question the study is designed to answer.
Is only one puncture attempt necessary to attain the radial artery? yes/no
Measured: maximum two hours
Secondary outcomes (6)
The number of puncture attempts required to attain the radial artery
Measured: maximum two hous

Questions about this trial
What is this clinical trial studying?
A study testing Artery puncture with ultrasound guidance and Artery puncture without ultrasound guidance in people with Radial Artery and Ultrasonography, 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 3 inclusion and 9 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 17 Nov 2025. 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?
Is only one puncture attempt necessary to attain the radial artery? yes/no (time frame: maximum two hours). 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 NCT01189188, which also lists 2 linked publications.
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 17 Nov 2025.
