Must Cannulation Technique of Vascular Access in Patients Undergoing Haemodialysis: Contributions for a Safe Nursing Intervention

The aims of this study are to: * Determine the AVF (arteriovenous fistula) survival of patients submitted to MuST compared to those submitted to RL (rope-ladder). * Determine the AVF (arteriovenous fistula) complication rate of patients submitted to MuST compared to those submitted to RL (rope-ladder). * Analyze the intensity of pain perceived by the patient with each cannulation technique under study.

The MuST is based on the association between the RL technique in that it uses the entire length of the available vessel through progressive rotation, and the buttonhole (BH) cannulation technique since there are three specific cannulation sites for each cannulation day during the week, meaning that each site is only cannulated once a week (allowing the puncture site to heal in between cannulations).
