Abstract

Background: Upper limb exercise has long been considered to be the main means to promote autogenous arteriovenous fistula (AVF) maturation, but in practice exercise intensity and compliance are both typically lacking. Several randomized controlled trials (RCTs) have demonstrated the good effects of functional resistance or pressure exercise in patients with AVF. However, many patients’ have difficulty complying with upper limb exercise programs without systematic health education. Therefore, we argue that resistance and pressure exercise supported by health education is actually the most beneficial for AVF patients. Methods: We randomly divided 114 patients into a control group and an experimental group of 57 patients each. In the control group, conventional care was used, and in the experimental group, online health education based on the IMB (Information-Motivation-Behavior skills) model and functional resistance and pressure upper limb exercises was implemented with the AVF side arm. The failure rate of AVF maturation, clinical maturation time, cephalic venous blood flow, vessel diameter, and vessel skin thickness were compared between the two groups. Results: Fifty-five cases were included for each in the final study. The primary outcome of this study was the failure rate of AVF maturation. Secondary outcomes included clinical maturation time, cephalic vein flow, vessel diameter, and vessel thickness. The failure rate of AVF maturation in the experimental group was significantly lower than that in the control group, and the clinical maturation time in the experimental group was significantly shorter than that in the control group. For the remaining three indicators, there were between-group effects, time effects, and interaction effects in both groups. Comparison between groups showed that there was no statistical difference in the observed indicators of cephalic vein flow, vessel diameter, or vessel thickness between the two groups before the intervention but that there was a statistical difference at the end of the 4th, 8th, and 12th weeks of the intervention. A 2 × 2 comparison also showed that there was a statistical difference between the three indicators at each time point within the two groups. Conclusion: IMB model-based online health education combined with functional resistance and pressure exercises can improve AVF maturation status and accelerate AVF maturation within 12 weeks of surgery.
