To clean your blood, the dialysis machine needs a safe way to take blood out of your body and return it after cleaning.
This is called your dialysis connection, or vascular access.
There are different types of connections. Some are made using your own blood vessels, while others use a special tube. Your dialysis connection is your lifeline.
Let's explore the different types of dialysis connections and how to protect them.
1. Catheter
1. Catheter
A flexible tube is placed into a large vein, usually in your neck or chest.
Blood flows through the tube to the dialysis machine and back to your body.
It can sometimes be used immediately.
It is often used when dialysis is needed quickly or when a fistula or graft is not suitable.
It has a higher risk of infection and other problems, so it is usually a short-term option.
2. Graft (AV Graft)
2. Graft (AV Graft)
A surgeon places a soft artificial tube under the skin to connect an artery and a vein, usually in your arm.
Needles are placed into the tube during dialysis.
It can often be used within a few weeks.
It is a good option when your own blood vessels are not suitable for a fistula.
It has a higher risk of infection than a fistula and may not last as long.
3. Fistula (AV Fistula)
3. Fistula (AV Fistula)
A surgeon connects one of your arteries directly to a vein, usually in your arm.
The vein becomes bigger and stronger.
Needles are placed into the vein during dialysis.
It usually takes several weeks to months to be ready.
It can last a long time and has a lower risk of infection.

How to take care of my graft or fistula (arm)
How to take care of my graft or fistula (arm)
Keep the area clean.
Do not wear tight clothing or jewelry over it.
Do not sleep on that arm or carry heavy bags with it.
Do not allow blood pressure checks or blood tests on that arm.
Check for a gentle buzzing feeling every day. Ask your nurse to show you how.
When to ask for help? If you notice redness, swelling, pain, fever, bleeding or fluid coming from your connection.
If the buzzing in your fistula or graft stops, contact your team immediately. Do not wait for your next session.
If you have heavy bleeding that will not stop, apply firm pressure with a clean cloth and seek emergency medical help.
