What is required when cannulating an AV Fistula?

When cannulating an AV fistula, the use of a tourniquet is essential for several reasons. A tourniquet aids in engorging the veins, making them more prominent and easier to access. This is crucial for successful cannulation as the veins need to be clearly visible and accessible for needle insertion. Proper application of the tourniquet allows for better visualization and facilitates a more straightforward process, minimizing discomfort and the likelihood of complications.

Although other items such as antiseptic wipes and local anesthetics may be relevant in the overall process of preparing for cannulation, the primary need during the actual cannulation phase is to ensure clear access by using a tourniquet. The pressure bandage has its role in post-cannulation care, but it is not a necessary requirement during the cannulation itself.
