How many treatments should a buttonhole be used to achieve optimal results?

The optimal number of treatments for a buttonhole technique, which is used in hemodialysis to create a consistent and accessible access point for needles, is generally 8-12 treatments. This range allows for adequate healing and maturation of the site, ensuring that the buttonhole becomes a reliable and less painful access point for subsequent treatments.

During these initial treatments, the area is conditioned to reduce the risk of complications such as infection or thrombosis. After approximately 8-12 treatments, patients typically report improved comfort and efficiency in their dialysis sessions. This approach balances the need for creating a durable access site while minimizing potential complications that could arise with underdeveloped or overused sites.
