Smart-glasses During the US-guided Radial Arterial Catheterization in Pediatric Patients: a RCT

The Usefulness of Smart-glasses During the Ultrasound-guided Radial Arterial Catheterization in Pediatric Patients: 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. 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.

Inclusion Criteria:

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

Exclusion Criteria:

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