About

Arteriovenous fistula is the preferred access for hemodialysis, and cannulation using a "button-hole" technique is increasingly recommended. By using the same two sites for cannulation there are reports of less risk of complications and less pain for the patient. However, button-hole cannulation can be difficult for the dialysis nurse, and failing cannulations can damage the AV fistula and increase patient discomfort. The investigators therefore will test whether a simple marking on the skin of the direction and angle of cannulation used in each specific patient could improve the probability of a successful and painfree cannulation.
