Smart-glasses During the Ultrasound-guided Radial Arterial Catheterization in Pediatric Patients by Trainees

The Usefulness of Smart-glasses During the Ultrasound-guided Radial Arterial Catheterization in Pediatric Patients by Less Experienced Trainees: a Randomized Controlled Trial

The primary objective of the study is to evaluate the effect of smart glasses (Head-mounted display Moverio BT-300 (Epson Inc., USA)) on the first-attempt success rate of radial artery cannulation in pediatric patients by less experienced trainees. This study hypothesizes that the use of smart glasses improves the hand-eye coordination and the first-attempt success rate of radial artery cannulation. This is a single-center, randomized, placebo-controlled study comparing the real-time ultrasound image through smart glasses (intervention group) or the ultrasound machine's monitor (control group) during the radial arterial cannulation in pediatric patients undergoing general anesthesia by less experienced trainees.

Inclusion Criteria:

• General anesthesia
• Arterial cannulation for hemodynamic monitoring, multiple blood sample

Exclusion Criteria:

• Unstable vital signs, significant arrhythmia or hypotension, Shock
• High risk of peripheral ischemia
• Skin disease, infection, hematoma, recent cannulation at theradial artery
