The aim of this clinical trial is to investigate the advantages of single-operator laser-assisted ultrasound-guidance comparing with traditional ultrasound guidance in peripheral venous catheterization.The primary question addressed is whether single-operator laser-assisted ultrasound-guidance could improve the first-attempt success rate of peripheral venous catheterization compared with traditional ultrasound guidance.

Ultrasound Guided Peripheral Vein Catheterization With or Without Laser-Assisted.
Other interventionIn group T, ultrasound-guided peripheral vein cannulation was performed using dynamic needle tip positioning technique. In group L, ultrasound-guided peripheral vein cannulation was performed using dynamic needle tip positioning technique with laser-assisted.
First-attempt success rate
The completion of the cannulation was defined as the presentation of the arterial waveform on the monitor.
