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.
