Caring for Your Dialysis Fistula: 5 Things to Avoid

Why fistula care matters

A dialysis fistula is a lifeline for patients on hemodialysis. If it fails, dialysis efficiency suffers, and creating a new vascular access requires time and surgery, which greatly affects quality of life. Small everyday habits are key to protecting your fistula.

5 things to avoid with your fistula arm

1. Don't have your blood pressure taken on that arm: the cuff temporarily stops blood flow through the fistula and may affect its patency—use the other arm
2. Don't lift heavy objects or strain the arm: avoid carrying heavy loads, using crutches, or repetitive forceful movements with the fistula arm
3. Don't wear tight watches, bracelets, or clothing: avoid anything that compresses the fistula, including your own body weight while sleeping
4. Don't have injections or blood drawn from that arm: clearly tell healthcare staff which arm has the fistula
5. Don't sleep on the fistula arm for long periods: be mindful of your sleeping position

How to check your fistula yourself

Each day, lightly touch the fistula with your fingers and feel for a continuous "buzzing" vibration, called the thrill, which indicates good blood flow. You can also listen closely for a continuous whooshing sound (the bruit). Check at the same times each day, such as morning and evening; once it becomes a habit, changes are easier to spot.

How often to follow up

In addition to regular dialysis sessions, follow the schedule your care team sets for fistula checks. If you notice a weaker or absent thrill, or reduced blood flow during dialysis, come in early rather than waiting for your next scheduled visit.

Caring for puncture sites

• Apply firm pressure after dialysis until bleeding has fully stopped
• Keep puncture sites clean and dry, and avoid scratching
• Report any redness, swelling, warmth, pain, or drainage at the puncture site promptly
