Abstract

Introduction: Arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. Whether acute arm movement impacts arteriovenous fistula (AVF) blood flow is unknown.

Methods: In this cross-sectional analysis, we evaluated AVF blood flow using an ultrasound device at resting and after three muscle movements for proximal (elbow flexion, shoulder adduction and abduction) or distal AVF (fist extension and flexion, fingers squeeze), without and with a 2 kg load.

Results: We included 23 patients (14 men), 53 ± 13 years, 26.1% with diabetes, on dialysis for a median time of 5.2 months. At rest, blood flow in proximal and distal AVF were 4355 (2470, 7233) mL/min and 2286 (2063, 2442) mL/min, respectively. There was no significant difference between blood flow at resting and any movement before and after load in either proximal or distal AVF (p > 0.05 for all comparisons).

Conclusion: Acute arm movement with or without load does not significantly alter the blood flow of mature AVF. These results demystify the general belief that patients should avoid AVF arm movement.

负荷和运动对动静脉瘘流动的影响。

动静脉瘘（AVF）是血液透析首选的血管通路。急性手臂运动是否影响动静脉瘘（AVF）血流尚不清楚。方法：在横断分析中，我们使用超声设备评估静置时和近端（肘关节屈曲，肩部内收和外展）或远端（拳头伸展和屈曲，手指挤压）三次肌肉运动后的AVF血流量，没有和有2kg负荷。结果：我们纳入23例患者（14名男性），53±13岁，26.1%患有糖尿病，透析时间中位数为5.2个月。静息时，近端和远端AVF血流分别为4355 (2470,7233)mL/min和2286 (2063,2442)mL/min。静息血流量和负荷前后任何运动的血流量在近端和远端均无显著差异（p < 0.05）。结论：有负荷或无负荷的急性手臂运动对成熟AVF的血流量无显著影响。这些结果揭开了人们普遍认为患者应避免动臂运动的神秘面纱。

期刊介绍： The Journal of Vascular Access (JVA) is issued six times per year; it considers the publication of original manuscripts dealing with clinical and laboratory investigations in the fast growing field of vascular access. In addition reviews, case reports and clinical trials are welcome, as well as papers dedicated to more practical aspects covering new devices and techniques. All contributions, coming from all over the world, undergo the peer-review process. The Journal of Vascular Access is divided into independent sections, each led by Editors of the highest scientific level: • Dialysis • Oncology • Interventional radiology • Nutrition • Nursing • Intensive care Correspondence related to published papers is also welcome.
