The cleaned blood then flows out of the machine through another tube placed into a nearby vein in the same arm. Most people have 3 dialysis sessions every week. Each session lasts about 3 or 4 hours.
Dialysis Access Site?
Before you can begin hemodialysis there need to be a way to remove the blood from the body (a few ounces at a time) and then return it. You arteries and venis are usually too small, so you will need surgery to create a vascular access site.

There are 3 kinds of vascular access site:- A. V. Flstula, A. V. Graft & Catheter - Permacath
- A. V. fistula (also called an arteriovenous fistula or A-V fistula), which is made by joining an artery and a vein under the skin in your arm. When the artery and vein are joinded, the pressure inside the vein increases, making the walls of the vein thicker & stronger. The stronger vein can then receive the needles used for hemodialysis. An A-V fistula usually takes 4 weeks to mature before it can be used for hemodialysis. The fistula can be used for many years.
- A.V graft (also called an arteriovenous graft or A-V graft), which is made by joining an artery and vein in your arm with a plastic tube. The plastic tube is placed under your skin, joining the artery to a vein. The graft is usually ready to use about 3 weeks after the surgery. A-V grafts are usually not as long lasting as A-V fistulas, but a well-cared-for graft can last several years.
- A Hemodialysis Catheter, which is inserted into a vein in the neck or below the collarbone for short-term use until your A-V fistula or A-V graft is healed and ready to use. A catheter is not used for permanent access
Investigation
You will most likely need some special tests to help the doctors decide the best type is vascular access and the best place to secure he access. The most common test is Doppler ultrasound.
Before surgery, you may have an elclectrocardiogram (ECG Or EXG), blood tests urine tests, and a chest x-ray to give your surgeon the latest information about your health. You may be given something to help you realx (a.mild tranquillizer) before you are taken into the operating room.
The surgeon will then create the A-V fistula or the A-V graf in one of your arms.
