Smart Glasses to Facilitate Ultrasound Guided Peripheral Intravenous Access in the Simulation Setting for Thai Emergency Medical Service Providers.

Purpose: The ultrasound-guided peripheral venous access (USGPIV) was reported as difficult for novices to perform. Smart glasses equipped with teleconference systems can display real-time ultrasound images to sonographers and consultants which can increase the success rate of this procedure. The purpose of this study was to assess the effectiveness of employing smart glasses for USGPIV. Patients and Methods: A randomized, simulation study was conducted in emergency medical service (EMS) providers at Srinagarind Hospital, Thailand, from January to April 2023. We randomized participants into two groups which included participants who wore smart glasses during procedures requiring USGPIV (the smart glasses group) and participants who performed USGPIV with no smart glasses (the non-smart glasses group). After participating in USGPIV cannulation training, the simulations were carried out. The primary outcome was the first-attempt success rate, with secondary outcomes including the procedure time and subjective difficulty. Results: Fifty participants were recruited for the study. The smart glasses group was superior to the non-smart glasses group both in terms of first-attempt success rate with no statistically significant (64% vs 60%; P = 0.460) and also demonstrated a shorter procedure time than the non-smart glasses group (25.5 sec vs 42.3 sec; P = 0.003). The participants reported the subjective difficulty score was higher in the smart glasses group (the visual analog scale, VAS = 8). Conclusion: In simulation scenarios, the smart glasses-assisted USGPIV could shorten the procedure time. However, our study did not find significant differences in the first pass success rate of USGPIV between the two groups.
