Simple buttonhole method

Constant Site (Buttonhole) Method

"Available data are suggesting that insertion of the hemodialysis needles in exactly the same spot for consecutive dialyses (the "buttonhole method) may be associated with fewer complications as compared with using different needle insertion sites for each dialysis. The buttonhole method is becoming popular among home hemodialvsis patients. This paper will describe the origin of the method, ear...

A simple method to create buttonhole cannulation tracks in a busy hemodialysis unit.

The preference for fistulae as the hemodialysis access of choice has led to a significant number of accesses that are less than ideal for cannulation. Buttonhole cannulation is ideal for such accesses, but the technique for creation provides major challenges. In 12 patients, buttonhole tunnel tracks were created by leaving the polyurethane catheter of a Clampcath hemodialysis needle indwelling ...

Should buttonhole cannulation be discontinued?

The arteriovenous fistula remains the preferred type of vascular access because of its higher patency and lower infection rates (1). Cannulation of the fistula remains a challenge for patients, caregivers, and nurses, often resulting in increased pain, stress, and vessel injury. The use of rotating puncture sites along the entire length of the fistula, or rope-ladder cannulation (RLC), was inte...

Sharp versus Blunt Dialysis Needle Use with Buttonhole Method: Open Randomised Trial.

BACKGROUND Current protocols recommend the use of a blunt needle to access the arteriovenous fistula via a buttonhole. This study aims to demonstrate whether a sharp needle can be used at the same buttonhole site without causing complications. GOAL To measure and compare fistula cannulation failures between the use of blunt and sharp needles. PLAN: Open-crossover randomised controlled trial. ...
