Indicating Direction and Angle for Cannulating of AV-fistula in Hemodialysis Patients

Not Applicable

Completed

• Conditions: Kidney Failure; Chronic Kidney Disease
• Interventions: Procedure: No skin drawing; Procedure: Skin drawing

• Registration Number: NCT01536548
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Percentage of successful cannulations	8 weeks	A successful cannulation is defined as being able to insert a blunt needle in both canals at the first attempt.

Secondary Outcome Measures

Name	Time	Method
Fear of cannulation	8 weeks	Patients describe on a Verbal Rating Scale (0-10) how strongly they fear the cannulation. Assessed once a week.
Difficulty of cannulation	8 weeks	Nurse and patients describe on a Verbal Rating Scale (1-6) how difficult the cannulation was experienced. All dialysis sessions are scored.
Pain at cannulation	8 weeks	Patients describe on a VAS scale (0-10) how painful the cannulation was experienced. Assessed once a week.
