Abstract

Introduction: Patients with arteriovenous fistulas are advised to avoid carrying heavy objects draped over the fistula arm. Awareness gradually leads to overprotection and a reduction in the use of the fistula arm. However, restricting motion in the fistula arm leads to decreased quality of life and diminished muscle strength. The current safety recommendations regarding lifting heavy items with the fistula arm are primarily based on experience. Few studies have provided evidence clarifying the scope of safe activity and the influence of load bearing on the continued patency of arteriovenous fistulas. Methods: This prospective observation was based on a long-term follow-up study in which 86 hemodialysis recipients with arteriovenous fistulas were randomized into either a dumbbell group or a handgrip group. The dumbbell group exercised with 6-lb dumbbells, while the handgrip group squeezed rubber balls. Postintervention primary patency and adverse events at the 6-month follow-up were analyzed. Results: No significant difference in postintervention primary patency was observed between the dumbbell group and the handgrip group at 6 months (97.4% vs 95.0%). There were two participants with high-flow fistulas in the dumbbell group and three in the handgrip group, with no significant difference between the two groups (5.3% vs 7.5%). In both groups, there were no other adverse events reported regarding cardiac failure, aneurysm, puncture site hematoma, or hemorrhage. Conclusion: Hemodialysis patients can safely use their fistula arm to lift objects weighing less than 6 lb, which encourages increased motion and helps preserve the functionality of the fistula arm.
