Radial artery cannulation in young children is challenging. A single-operator laser-assisted ultrasound-guidance system was invented to project the path of the target artery on the skin surface.

The hypothesis was that this system would improve the first-attempt success rate of radial arterial cannulation in young pediatric patients relative to traditional ultrasound guidance.

This single-center, prospective, parallel-group, randomized controlled study enrolled pediatric patients (n = 80, age less than 2 yr) requiring radial artery cannulation during general anesthesia.

The participants were randomized into the traditional ultrasound-guidance group or the single-operator laser-assisted ultrasound-guidance group. After inducing general anesthesia, ultrasound-guided radial artery cannulation was performed by two experienced operators.

The primary outcome was the first-attempt success rate. The secondary outcomes included the procedure time to success within the first attempt, midmost rate of first attempt, first needle-tip position, and average number of adjustments.
