简要总结
Head-mounted displays (HMD) in medical practice are current research topics. The goal of this clinical trial is to learn if HMD would improve the safety and efficacy in ultrasound-guided central venous catheterization. The main questions it aims to answer are: Does HMD reduce the procedure time and increase the catheterization success rate in ultrasound-guided central venous catheterization. Does HMD increase the satisfaction score of operators and patients. Researchers will compare HMD with the conventional ultrasound in central venous catheterization. Operators will receive either HMD or conventional ultrasound machine to guide internal jugular vein catheterization. The procedure time, puncture success rate, complication and satisfactory score will be recorded.

结局指标
主要结局
Total catheterization time
时间窗: From application of the ultrasound probe to skin to the end of catheterization
The total catheterization time is defined as the period between the probe positioning on the patient's skin and insertion of the catheter, irrespective of the attempt number of the venous catheterization.
