At what angle should you insert a HDC (Hollow Drug Catheter)?

Inserting a Hollow Drug Catheter (HDC) at an angle of 30-45 degrees is considered optimal for ensuring proper placement while minimizing potential complications. This angle allows for effective access to the vascular system while maintaining enough control over the catheter's trajectory. When inserted at this angle, the risk of puncturing the arterial wall or causing significant trauma to surrounding tissues is reduced, as the catheter can more easily navigate the anatomy of the vessel.

In clinical practice, maintaining this angle also helps in achieving a balance between accessibility and safety. It supports proper visualization of the insertion site and allows for careful insertion, which is crucial for successful catheter placement and functionality. In contrast, steeper angles could pose a greater risk for complications, such as difficulty entering the vessel or increased chances of adverse effects. Therefore, the chosen angle of 30-45 degrees is aligned with established protocols that prioritize patient safety and effective catheterization.
