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

Not Applicable
Completed
Conditions
Kidney Failure
Chronic Kidney Disease
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
NameTimeMethod
Percentage of successful cannulations8 weeks

A successful cannulation is defined as being able to insert a blunt needle in both canals at the first attempt.

Secondary Outcome Measures
NameTimeMethod
Fear of cannulation8 weeks

Patients describe on a Verbal Rating Scale (0-10) how strongly they fear the cannulation. Assessed once a week.

Difficulty of cannulation8 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 cannulation8 weeks

Patients describe on a VAS scale (0-10) how painful the cannulation was experienced. Assessed once a week.
