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

Fresenius Medical Care Deutschland GmbH101 enrolled

Overview

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).

Outcomes

Primary Outcomes

Vascular access survival rate

Vascular access (VA) survival rate at 12 months and determined by the percentage of fistulas in use from the beginning of the study to the date of the first clinical intervention by angioplasty or vascular surgery, to maintain or restore patency - "unassisted patency".

Time frame: 12 months after start of study

Secondary Outcomes

Arteriovenous fistula survival rate

Arteriovenous fistula (AVF) survival rate at 12-month and determined by the percentage of fistulas in use from the study start to the date of access abandonment due to dysfunction, patient abandonment, or death, treatment change modality or study end.
