How to Protect the IAVF(arteriovenous fistula) in Kidney Disease

IAVF(arteriovenous fistula) is a permanent vascular conduit which can be used for
a long time.
Usually, the artery would flow through the capillary, in which the blood would exchange substances with the tissues, then it would converge in the vein, then flows back to the heart, forming a artificial blood circuit. In other words, the blood would not flow through the capillaries again; it flows straight back to the heart through the vein.
Internal fistula has a high blood volume like artery, and can also be easily pierced like vein. After the surgery, the walls of the vein would gradually thicken. Only if the patients can take care of the fistula and secure its smoothness can the process be done successfully.Creatinine 12.21: Is It Good to Make Fistula Now

2. During dialysis, patients should lie down in a comfortable position. Patients should not bend their arms in which the fistula is located too much, which could make puncture needles pierce the blood vessels, causing subcutaneous bleeding.
3.After the needles are pulled out, the best way to stop bleeding is punctiform oppression, in which method the thumb and index finger would oppress the puncture spot for twenty minutes.

Patients need to observe the throbbing of the fistula and the vibration of the blood vessels on a regular basis. If they find anything abnormal, they should get in touch with the doctors in the dialysis units.
6. On non-dialysis days, they should do moderate blood vessel filling exercise, and massage their blood vessels softly.What Can I Do When My Dialysis Stops
