What is a significant advantage of using the axillary vein for central venous access?

Using the axillary vein for central venous access has a significant advantage of lower infection risk compared to internal jugular placement. The axillary vein is located deeper within the body under the pectoralis major muscle and is less exposed to external contamination than the internal jugular vein, which is more superficial and exposed to the environment. The axillary region also tends to be less frequently accessed, which further contributes to a reduced risk of infection for procedures involving central venous catheters.

In addition, the anatomical positioning of the axillary vein minimizes patient discomfort and procedural complications related to access, embodying a strategic benefit for patients requiring long-term central venous access. This aspect is particularly beneficial for patients needing frequent blood draws or therapies, as it can reduce the number of invasive procedures and limits the potential sites where infection could occur.

While considerations regarding the suitability for chronic kidney disease, success rates of insertion, and risks of thrombosis are important in a broader context of vascular access, they do not convey the same advantage in terms of current infection control practices and sterile procedural protocols as those presented by the lower infection risk with axillary vein access.
