In this single-center, prospective, randomized study, emergency physicians performed one puncture with each device in a randomized order. No emergency physicians used a pocket-sized ultrasound for central vascular catheter insertion in clinical practice. A medium-fidelity training model was used. Each image was judged based on an image quality scale from 0 to 5. Twenty emergency physicians were included: nine females (45%), median experience 2.5£¿years [2.0;4.3]. The median time to achieve a puncture with the conventional ultrasound device was 22£¿s [17;26] versus 28£¿s [13;43] with the pocket-sized ultrasound (p£¿=£¿0.43). Eighteen (90%) emergency physician punctures were successful with the conventional ultrasound device versus 18 (90%) with the pocket-sized ultrasound (p£¿=£¿1). The image quality was 4 [3;5] in the conventional ultrasound device group versus 4 [3;5] in the pocket-sized ultrasound group (p£¿=£¿0.32). Pocket-sized ultrasound and conventional ultrasound device performances are not statistically different for internal jugular vein-guided ultrasonography in a training model. These results must be confirmed in a clinical study %K Emergency medicine %K point-of-care systems %K ultrasonography %K central venous catheters %U https://journals.sagepub.com/doi/full/10.1177/1129729818812733
