Evaluation of a simplified augmented reality device for ultrasound-guided vascular access in a vascular phantom.

Abstract:

STUDY OBJECTIVE:To investigate whether a novel ultrasound device may be used with a simplified augmented reality technique, and to compare this device with conventional techniques during vascular access using a vascular phantom. DESIGN:Prospective, randomized study. SETTING:Anesthesiology and Pain Medicine departments of a university-affiliated hospital. PARTICIPANTS:20 physicians with no experience with ultrasound-guided techniques. MEASUREMENTS:All participants performed the vascular access technique on the vascular phantom model using both a conventional device and the new ultrasound device. Time and the number of redirections of the needle until aspiration of dye into a vessel of the vascular phantom were measured. MAIN RESULTS:The median/interquartile range of time was 39.5/41.7 seconds versus 18.6/10.0 seconds (P < 0.001) and number of redirections was 3/3.5 versus 1/0 (P < 0.001) for the conventional and novel ultrasound devices, respectively. CONCLUSION:During vascular access in a vascular phantom model, the novel device decreased the time and the number of redirections significantly. The device successfully improved the efficiency of the ultrasound-guided vascular access technique.
