Implementing the buttonhole method using the Biohole peg in a busy dialysis unit: a report of the development of current practice.

A report outlining experience gained from the practice of introducing the buttonhole (BH) method of arteriovenous cannulation using the Biohole device, a polycarbonate sterile peg, to form the tunnel tracks. The author's findings are discussed informally and compared with current published literature to provide encouragement to nursing colleagues who are interested in introducing this method of needling, using the peg, into a typically busy haemodialysis unit.
