What does internal access typically refer to in the context of dialysis?

In the context of dialysis, internal access typically refers to the establishment of a vascular access that is created within the body to facilitate the process of dialysis. This includes both grafts and fistulas.

A graft involves surgically inserting a synthetic tube that connects an artery to a vein, providing a site for dialysis treatment. A fistula, on the other hand, involves directly connecting an artery to a vein, generally in the arm, which allows for blood to flow more easily during dialysis. Both methods are considered internal because they utilize the patient's own blood vessels, thus minimizing the risks associated with external access methods like catheters.

This timing of vascular access is critical for ensuring sufficient blood flow during treatments, which is essential for effective dialysis. Internal access methods, such as grafts and fistulas, generally have longer lifespans and lower infection rates compared to external options like catheters, contributing to better overall patient outcomes in dialysis.
