Brief summary
Real-time ultrasound guidance for central venous catheter catheterism is recommended in order to reduce complication, in particular for internal jugular site1. Nevertheless, the usefulness of ultrasound guidance for subclavian approach remains controversial, in particular because needle visualisation is more complex as compared to jugular site2,3. New magnetic devices (Needle-pilotTM device, Samsung Healthcare) could theoretically allow a better needle visualisation and a better success rate. The investigators hypothesize that such device could improve the feasibility of subclavian catheterism. As this device has not been evaluated in patients, the investigators decided to perform a simulation study on a human torso mannequin. This methodology has been already used by Vogel et al in 20154. The main objective aims to compare the procedure time between conventional real time ultrasound guidance and guidance with Needle-pilot™ device.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| First puncture success delay | during the procedure | comparison of time (in seconds) between first puncture and successful blood-aspiration on a subclavian venous torso mannequin. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Failure Rate | during the procedure | Failure is defined as a puncture time \> 300 seconds. The criterion corresponds to an absolute value: failure or not |
| Cutaneous wall | during the procedure | Counting the number of times each participant will puncture the wall of the mannequin before succeeding in puncturing the vessel with the 2 techniques and comparing this number between groups. |
| Posterior wall | during the procedure | Number of posterior vessel wall penetration |
| Puncture comfort | immediately after the procedure | Operator puncture comfort feeling is assessed from 0 to 10 by each participants for each technique. |
