Central venous catheterization
Central venous catheterization is a core skill set for care of critically ill patients. Whether it is for fluid resuscitation, vasopressor administration, multiple drug infusions, hemodialysis or other indication, it is vital that front-line health care providers are able to perform this skill safely and competently. In the following video clips and images, we will highlight selected fundamental points to enhance your understanding and performance of this procedure.
Please check out this excellent video by New England Journal of Medicine. While this video discusses internal jugular cannulation exclusively, the Seldinger technique (over-the-wire technique) and execution of the procedure is similar regardless of site.
Pre-performance venous assessment
Prior to set-up sonographically interrogate the access site to ensure patency of internal jugular vein and optimal access site. Many beginners turn the head to the contra-lateral side, which can lead to significant anatomical distortion.
Ensure your probe is always capturing the tip of the needle, as it easy to confuse the shaft. In this clip, we see in short axis we don't appear to enter the vein, but in the long axis we are. Be careful!
Confirmation of wire placement
After insertion of the wire, it should be visualized for its anatomical course.
