Summary

This study tests a new laser-assisted ultrasound technique to help doctors place a small tube (catheter) into the wrist artery of children under 2 years old during major surgery. The goal is to see if this method improves first-attempt success and reduces complications compared to standard ultrasound. About 360 children will take part.
