Dialysis Access Management
What Is Dialysis Access Management?
VASCULAR ACCESS (OR HEMODIALYSIS) IS A WAY TO REACH THE BLOOD FOR HEMODIALYSIS
Hemodialysis is a type of treatment for kidney failure (end-stage kidney disease or ESRD). It uses a machine that holds a filter called a dialyzer. As blood flows through the dialyzer, waste is removed and fluid and chemicals are balanced.
HOW HEMODIALYSIS IS DONE
Two needles are inserted into a blood vessel (called an arteriovenous fistula or AV fistula) or an arteriovenous graft (or AV graft), usually in your arm. Each needle is attached to a tube. One tube carries your blood into the dialyzer, where it’s cleaned. Clean blood returns to your body through a second tube and needle. If this treatment has to be done in an emergency, a plastic tube (catheter) is inserted into a large vein, typically in the neck or groin. This catheter helps carry blood to and from the dialysis machine.
YOUR EXPERIENCE: PROBLEMS TO WATCH FOR
- Hemodialysis usually takes about 3 to 5 hours. It’s usually done 3 times a week.
- You’ll have a regular schedule for your hemodialysis. Many centers have evening and weekend hours as well as weekday hours to help you continue working. Some centers also offer overnight treatments.
- A trained nurse or technician connects you to the dialysis machine. He or she watches for problems and makes sure you are comfortable.
- During treatment, only a small amount of blood (about 1 cup) is out of your body at any one time.
During your treatments, you may have a headache, muscle cramps, nausea and vomiting, chest and back pain, itching, and fever and chills. Make sure you tell your nurse or technician if you have any of these symptoms.
Some people are able to learn to use dialysis at home. Home dialysis lets you schedule treatments when it’s most convenient. You may have more frequent treatments, but for shorter periods of time. You may also do overnight treatments.
Get immediate medical help or call your doctor, nurse or dialysis technician if you have any of these symptoms after treatment:
- Chest or back pain
- Tiredness (fatigue)
- Bleeding from the needle site
- Shortness of breath
- Fever or chills
- Headache or lightheadedness
- Nausea or vomiting
- Muscle cramps
- Pain, warmth, or redness at your access site
- Inability to feel your blood flow (called a thrill) in your AV fistula or graft
