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.

Interventions

PROCEDURESkin drawing

Mark direction and angle for cannulation with a pencil on the skin

PROCEDURENo skin drawing

Standard practice; i.e. no marks on skin to help find correct direction and angle for introducing needles

Design outcomes

Primary

MeasureTime frameDescription
Percentage of successful cannulations8 weeksA successful cannulation is defined as being able to insert a blunt needle in both canals at the first attempt.

Secondary

MeasureTime frameDescription
Difficulty of cannulation8 weeksNurse and patients describe on a Verbal Rating Scale (1-6) how difficult the cannulation was experienced. All dialysis sessions are scored.
Fear of cannulation8 weeksPatients describe on a Verbal Rating Scale (0-10) how strongly they fear the cannulation. Assessed once a week.
Pain at cannulation8 weeksPatients describe on a VAS scale (0-10) how painful the cannulation was experienced. Assessed once a week.
