An access is needed for you to get hemodialysis. Using the access, blood is removed from your body, cleaned by a dialyzer, then returned to your body.
Usually the access is put in a person's arm. But it can also go in your leg. It takes a few weeks to a few months to get an access ready for hemodialysis.
Taking good care of your access helps make it last longer.
Prevent Infection in Your Access
Keep your access clean. Wash the access with soap and water every day to decrease your risk of infection.
DO NOT scratch your access. If you scratch open your skin at the access, you could get an infection.
To prevent infection:
- Avoid bumping or cutting your access.
- DO NOT lift anything heavy with the arm with the access.
- Use your access for hemodialysis only.
- DO NOT let anyone take your blood pressure, draw blood, or start an IV in the arm with the access.
Keep Blood Flowing Through Your Access
To keep blood flowing through the access:
- DO NOT sleep or lie on the arm with the access.
- DO NOT wear clothes that are tight around the arms or wrists.
- DO NOT wear jewelry that is tight around the arms or wrists.
Checking Your Access
Check the pulse in your access arm. You should feel blood rushing through that feels like a vibration. This vibration is called a "thrill."
Have the nurse or technician check your access before every dialysis.
When to Call the Doctor
Call your health care provider if:
- You have any signs of infection, including redness, pain, pus, drainage, or you have a fever over 101°F (38.3°C).
- You do not feel a pulse at your access.
