    Introduction: Since the introduction of the wearable head-up displays, there has been much interest in adopting these devices in clinical settings. Increasingly, more studies are being published in literature about their use to increase efficacy of workflow in the hospitals and clinics. In this study, we report the use of a novel video capture and streaming device that has capability to stream ultrasound images to a head-up display screen on Google Glass. This system was successfully utilized in supraclavicular nerve block.

    Methods: We devised a novel video capture and streaming device that is capable of broadcasting videos via a password wireless network to a wearable head-up display. This system was connected to the ultrasound machine via High Definition Multimedia Interface (HDMI). Voice controlled video streaming software was installed on Google Glass.

    Results: Ultrasound images were transmitted to Google Glass head-up display in real time without delays. The senior author (SRC) wore Google Glass to perform supraclavicular nerve block. He did not break the line of his sight towards the needle and did not divert his attention to look at the ultrasound monitor. The patient underwent the procedure without complications.

    Conclusions: Head-up display allowed the clinician to monitor ultrasound images without stopping the procedure and turning his head to view the ultrasound screen. Head-up display has potential to enhance efficacy of ultrasound-guided procedures by eliminating the need to divert attention while performing critical procedural steps.

    Patient Care: Head-up display system that is capable of projecting ultrasound images in the direct line of sight can be beneficial in performing ultrasound-guided procedures. Future trials are needed to test the same system in different types of ultrasound-guided procedures to refine and modify the current prototype to improve head-up display system that is optimized for ultrasound guided procedures. The operating surgeon wore the device without looking at the normal ultrasound output screen, and successfully finished the clinical procedure. Advancement in head-up display technology has potential to increase safety and efficacy of ultrasound-guided procedures.

    Learning Objectives: 1) Describe the potential role of wearable computing device in ultrasound-guided procedures 2) Discuss in small groups shortcomings of the currently available head-up display system and suggest improvement that can be made 3) Identify an effective way to utilize wearable head-up display system in surgical procedures
