Brief summary
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.
Interventions
DEVICESmart glasses
The real-time ultrasound image is displayed through head-mounted display Moverio BT-300 (Epson Inc., USA) during the radial arterial cannulation.
DEVICEControl
The real-time ultrasound image is displayed by the ultrasound machine's monitor during the radial arterial cannulation.
