Application of Smart Glasses During Ultrasound Guided Peripheral Venous Access: a Randomized Controlled Crossover Pilot Study

Investigators aimed to explore the feasibility of smart glasses connected to a wireless ultrasound transducer for the peripheral venous access. Residents who have basic skills of ultrasound guided procedure participate in the simulation. Each participant plays the following two roles for ultrasound guided peripheral venous access; ultrasound guided peripheral venous access with and without wearing smart glasses. The order of performing two roles is determined by a randomized process and the gap between two roles are five days. The primary outcome is the time of successful blood aspiration, and secondary outcomes are first time success rate, the number of skin puncture, the number of needle redirection, the number of head movement, and subjective difficulty.
