Ultrasound-guided central venous access using Google Glass

Area of Science:

• Medical technology
• Procedural training
• Point-of-care ultrasound

Background:

• Ultrasound use is standard for bedside procedures, but screen viewing can cause head movements.
• Head movements may lead to hand instability, especially in novices.
• Google Glass offers a head-mounted display for real-time visualization.

Purpose of the Study:

• To assess Google Glass feasibility for ultrasound-guided procedures.
• To evaluate its impact on medical practitioners of varying training levels.
• To explore potential benefits of head-mounted display technology in procedural guidance.

Main Methods:

• Forty participants with diverse training levels were randomized.
• One group used Google Glass for ultrasound-guided central line placement.
• The control group used traditional ultrasound equipment.
• Eye and hand movements were analyzed via video recording.

Main Results:

• All participants successfully completed the procedure.
• Google Glass users had longer procedure times across all training levels.
• Increased needle redirections were observed in the Google Glass group.
• A reduction in head movements was noted with Google Glass use.

Conclusions:

• Ultrasound-guided procedures are feasible with Google Glass.
• While increasing procedure time and needle redirections, Google Glass use reduced head movements.
• This technology shows potential for improving procedural stability by minimizing head movements.
