In this article, we extensively discuss the usage of central venous catheters（CVCs）, CVC-related complications and risks, criteria for CVC thickness, multiple approaches of real-time ultrasound-guided CVC puncture techniques, determination of ideal CVC insertion lengths, and the peripherally inserted central catheter insertion method. It is important to understand the characteristics of ultrasound to be able to perform real-time ultrasound-guided CVC insertion more accurately and safely and to learn approaches other than the ones with which the attending anesthesiologist is familiar. Understanding the condition of the target vessel during the pre-scan procedure and ability to switch to another approach if necessary are crucial for better management in each case.
