Hemodialysis access monitoring and surveillance, how and why?
Hemodialysis access is the 'life line' for patients on renal replacement therapy. Vascular access failure and complications are the second leading cause for hospitalization of patients on hemodialysis. The concept of access monitoring is based on the basic tenet that identification of patients at risk of developing future access failure, coupled with elective intervention will decrease the inci...
متن کاملSurveillance and Monitoring of Dialysis Access
Vascular access is the lifeline of a hemodialysis patient. Currently arteriovenous fistula and graft are considered the permanent options for vascular access. Monitoring and surveillance of vascular access are an integral part of the care of hemodialysis patient. Although different techniques and methods are available for identifying access dysfunction, the scientific evidence for the optimal m...
متن کاملDynamic venous access pressure ratio test for hemodialysis access monitoring.
BACKGROUND Early recognition of arteriovenous graft (AVG) dysfunction in hemodialysis (HD) patients followed by prompt corrective procedures reduces AVG thrombosis rates and lengthens access survival. We developed a method to prospectively monitor AVGs that uses an algorithm to calculate venous access pressure (VAP) during HD from the venous drip chamber pressure (VDP). METHODS Sham HD with b...
متن کاملSurveillance of Hemodialysis Vascular Access with Ultrasound Vector Flow Imaging
The aim of this study was prospectively to monitor the volume flow in patients with arteriovenous fistula (AVF) with the angle independent ultrasound technique Vector Flow Imaging (VFI). Volume flow values were compared with Ultrasound dilution technique (UDT). Hemodialysis patients need a well-functioning vascular access with as few complications as possible and preferred vascular access is an...
متن کاملSurveillance of arteriovenous hemodialysis access: a systematic review and meta-analysis.
OBJECTIVES Hemodialysis centers regularly survey arteriovenous (AV) accesses for signs of dysfunction. In this review, we synthesize the available evidence to determine to what extent proactive vascular access monitoring affects the incidence of AV access thrombosis and abandonment compared with clinical monitoring. METHODS We searched electronic databases (MEDLINE, EMBASE, Cochrane CENTRAL, ...
