An interventional study of Intensified Monitoring in Vascular Access Malfunction, Vascular Access Complication and Vascular Access Site Occlusion, sponsored by Shanghai Zhongshan Hospital. Status unknown. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2020-06-05.
Sponsored by Shanghai Zhongshan Hospital · Not applicable, Interventional, and Supportive care
Whether intensive monitoring and preemptive intervention has an positive clinical effect on arterio-venous fistula (AVF) maintenance is a new issue in hemodialysis (HD) patient management. This study aims to explore the clinical value of intensive monitoring and preemptive intervention on AVF, so to decide the best follow-up items and frequency.
Shanghai Zhongshan Hospital is the lead sponsor of 636 studies on the registry; 283 are open to participants now.

Exclusion Criteria:
In this group patients receive intensive monitoring and preemptive intervention. AVF surveillance refers to using non-invasive devices to check for the haemodynamic consequences of stenosis by measuring Qa every month. Clinical assessment refers to monitoring for any presence of stenosis by (i) physical examination, by means of visual inspection and presence of abnormal thrill, bruit or pulse and (ii) checking for signs of access dysfunction during dialysis: difficult cannulation, increase in dynamic arterial or venous pressure, inability to achieve the prescribed dialysis blood pump flow (Qb), prolonged bleeding after needle removal, access recirculation or a drop in Kt/V. Preemptive intervention is performed as long as problems are recognized, including health education and timely surgery.
Other: Intensified Monitoring
In this group patient receive traditional AVF monitoring, includes clinical assessment for any presence of stenosis by (i) physical examination, by means of visual inspection and presence of abnormal thrill, bruit or pulse and (ii) checking for signs of access dysfunction during dialysis: difficult cannulation, increase in dynamic arterial or venous pressure, inability to achieve the prescribed dialysis blood pump flow (Qb), prolonged bleeding after needle removal, access recirculation or a drop in Kt/V.
Apart from clinical assessment, use non-invasive devices to check for the haemodynamic consequences of stenosis by measuring Qa, using either indicator dilution techniques or duplex ultrasound every month.
