About

The study will compare two different positions of the ultrasound machine during simulated CVC positioning.

The position of the ultrasound machine will be randomized. Group A will perform the procedure with the ultrasound monitor facing them, while subjects randomized to group B will perform the procedure with the ultrasound machine positioned at a 90° angle to their visual axis.

Full description

We will recruit medical trainees affiliated with the 'Anesthesia and Intensive Care' and 'Emergency Medicine' schools. Data collected for each participant will include: age, gender, specialty school, year of specialization training, expertise in using ultrasound for ultrasound-guided procedures. Once informed consent is obtained, subjects will be divided through simple randomization (a list generated in advance with Excel and subjected to the opaque envelope method) into two groups: A and B. All subjects will be asked to perform CVC placement using the simulator through an 'oblique in-plane' approach. Subjects randomized to group A will perform the procedure with the ultrasound monitor facing them, while subjects randomized to group B will perform the procedure with the ultrasound machine positioned at a 90° angle to their visual axis.
