|Official Title:||The Outcomes of Arteriovenous Fistula (AVF) Cannulated From Different Direction in Maintenance Hemodialysis Patients.|
|Study Start Date :||September 2012|
|Actual Primary Completion Date :||April 2013|
|Actual Study Completion Date :||April 2013|
Experimental: Same direction cannulation
The inserted direction of arterial needle is same as the direction of blood flow.
Other: Same direction cannulation
The puncture direction of the arterial needle is same as the blood flow in every hemodialysis session.
Active Comparator: Opposite direction cannulation
The inserted direction of arterial needle is opposite to the direction of blood flow.
Other: Opposite direction cannulation
The puncture direction of the arterial needle is opposite to the blood flow in every hemodialysis session.
- Prevalence of AVF aneurysm and stenosis. [ Time Frame: 12 months ]Compare the prevalence of AVF aneurysm and stenosis between two groups during 12 months.
- Proportions of AVF dysfunction in different groups. [ Time Frame: 12 months ]Compare the proportions of AVF dysfunction between two groups during 12 months.
- The size of venous aneurysm. [ Time Frame: 12 months ]Measure the maximum size of venous aneurysm by using ultrasonography at month 12.
- Diameter of venous stenosis. [ Time Frame: 12 months ]Measure the minimum diameter of venous stenosis by ultrasonography at month 12.
- Percentages of unsuccessful cannulations. [ Time Frame: 12 months ]Unsuccessful cannulations include mis-cannulation, cannulation ease, hematoma, more than once cannulation at arterial site.
- Events of AVF obstruction. [ Time Frame: 12 months ]AVF obstruction and the following treatments as central venous catheters and interventions will be recorded and compared between two groups during 12 months.
