Overview
Brief Summary
Arteriovenous fistulae are preferred among methods of providing blood access for hemodialysis. For each hemodialysis treatment, the fistula is cannulated usually with two needles. One, the arterial needle, allows the blood to be withdrawn from the patient into the dialysis circuit and then it is returned by the second or venous needle. The success of arteriovenous fistula cannulation is dependent on many variables and these are affect the dialysis adequacy.
Detailed Description
As hemodialysis prescriptions are usually three times weekly (4 to 8 h), a fistula or graft for hemodialysis will be punctured twice each dialysis treatment or at least 312 times per year. To allow healing of the tissues damaged during each cannulation, optimal cannulation practice is required by rotation of the needle insertion sites each dialysis treatment. Vascular access (VA) has been justly described as both the lifeline and the Achilles' heel of hemodialysis therapy, making blood purification itself possible while simultaneously often constituting a limiting factor in treatment adequacy.

Outcomes
Primary Outcomes
Number of Fistula Needle Direction
Time Frame: up to 12 weeks
The hemodialysis nurse who cannulate the patient's fistula fill the data form. There is two options about fistula direction as antegrade or retrograde.
Number of Cannulation Method
Time Frame: up to 12 weeks
The hemodialysis nurse who cannulate the patient's fistula fill the data form. There is three options about cannulation method as puncture, buttonhole, and rope ladder methods.
Number of Fistula Needle Rotated
Time Frame: up to 12 weeks
The researchers look to the fistula needle while it inserts to the fistula. There is two options as needle rotation is yes or no.
Number of Arterial and Venous Needle Been on the Same Line
Time Frame: up to 12 weeks
The researchers look to the arterial and venous line whether they are the same venous line.
