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-pilotâ„¢ device.
