Which of the following is NOT recommended for temporary access in hemodialysis?

The subclavian vein is not recommended for temporary access in hemodialysis primarily due to the risk of complications associated with this site. Although it can be technically more accessible and offers some benefits in terms of flow, the subclavian vein has several significant drawbacks. One of the key concerns is the higher chance of complications, such as pneumothorax, which occurs when the pleural space is inadvertently punctured during catheter placement. Additionally, using the subclavian vein can lead to long-term complications, such as venous occlusion or stenosis, which can further complicate future dialysis access.

In contrast, the external jugular, femoral, and internal jugular veins are more commonly used for temporary hemodialysis access. These sites pose fewer risks for immediate complications and are generally more straightforward to cannulate. The internal jugular vein, in particular, is often preferred for its relatively straight course and direct access to the central venous system, which allows for better blood flow during dialysis procedures. By understanding the risks associated with each site, particularly for temporary dialysis access, practitioners can make more informed decisions to enhance patient safety and care.
