LESLEY C. DINWIDDIE

Of the many issues currently being addressed to improve arteriovenous access for dialysis, cannulation has received little attention. This session was planned to address the specific challenges encountered in cannulation for dialysis.

Leading off the program, Lesley Dinwiddie, MSN, RN, University of North Carolina-Chapel Hill, North Carolina, addressed “The Challenges of Cannulation in Dialysis Today.” She noted that the Dialysis Outcomes Quality Initiative (DOQI) recommendation for the creation of more fistulas has led to the need for more expert decision making with respect to when and how to cannulate access. Patient anxiety at the prospect of being cannulated by someone whose cannulation skills are unknown or have been experienced as lacking was discussed. The need for dedicated expert cannulators and the promotion of self-cannulation were discussed.

Gaye Case, BSN, RN, Renal Care Group, Jackson, Mississippi, presented “Access Preservation: Single versus Multiple Cannulators.” This unique study compared the access history of 84 hemodialysis patients divided into two groups: those on home hemodialysis and those who dialyzed in-center. Only licensed staff can-nulated in-center patients and there was relatively little staff turnover. Data collected were numbers of accesses, access throm-boses, and infections. The audience indi-cated by a show of hands that they believed the access of the home hemodialysis patients who had a single cannulator for more than 90% of their sticks would have better survival. Surprisingly, there was little difference in access survival, but there were considerably more thromboses in the in-center group.

The benefits and challenges of selfcannulation, as well as the buttonhole technique, were the subject of home hemodialysis patient, George Harper, MEd, Rome, Georgia. Due to pressing patient advocate duties George had at home (testimony at the State Senate), he could not be present but sent a hard copy of his presentation. The presider presented his excellent tips on self-cannulation based on 20 years of experience, as well as his motivation to learn this art. Harper strongly encouraged the professionals in the audience to promote self-cannulation. He also detailed his experience with the buttonhole technique of cannulation, and the presentation concluded with a 3-minute video clip demonstrating self-cannulation of his buttonholes.

Rounding out the program was the presentation of Deborah Brouwer, RN, VASCA, Inc., McMurray, Pennsylvania, who was a nursing representative on the Vascular Access Committee of the DOQI. She pointed out at the beginning of “Cannulation Camp Revisited” that current knowledge of cannulation is based on experiential art and theory, and is not sci-entifically tested. Cannulation of a new arteriovenous fistula was discussed, including choice of staff, patient educa-tion, needle size, the use of only one nee-dle and the catheter (and how to choose which needle: arterial vs venous), pain control, tourniquet use, and needle removal. The differences in technique for the matured fistula followed, and finally, graft cannulation was reviewed.
