Arteriovenous Fistula Cannulation

The arteriovenous (AV) fistula is the primary approach for dialysis. Thanks to its high rate of patency and a great capacity to cure puncture wounds.

The most common type of arteriovenous fistula is one that forms at the patient’s wrist and links the radial artery to the cephalic vein. A fistula can be created in the upper arm by linking the brachial artery to the axillary vein or another upper arm vein, all of which go to the subclavian vein. A leg fistula can also develop in individuals with limited access choices.

It’s important to decide on the access needle location prior to skin preparation and needle cannulation because the placement of access needles and their orientation might vary.

AV fistulas with deep, tiny, or stiff vessels might be difficult to cannulate on the first try. Thus, vein finders are quite important.  

SIFVEIN-5.2, for example, has a maximum scan depth of 10 millimetres, making it ideal for mapping out the veins in the arm and forearm. This permits safe catheter placement into a collapsed central vein, as well as repeated direct puncture of a femoral vein.

An indwelling dual lumen catheter is not required with the SIFVEIN-5.2, which lowers the risk of bloodstream infection.

It’s possible to utilize vein finder real-time guidance to adjust the needle tip placement when the traditional technique of inserting a needle fails (no blood return, difficulty advancing the catheter, and so on).

Therefore, using a vein finder allows for real-time guided and precise vascular cannulation, which may have a major influence on patients as well as hospital budgets.
