Complete Guide to Dialysis Access Care and Maintenance
Dr. Feliciano Serrano
Vascular & Dialysis Specialist
For dialysis patients, proper care of your vascular access is essential for successful treatment. Your access is truly your lifeline—it allows the dialysis machine to safely clean your blood. As a board-certified interventional nephrologist, I've seen how proper access care can prevent complications and improve quality of life.
Types of Dialysis Access
There are three main types of vascular access for hemodialysis, each with unique care requirements:
Arteriovenous Graft (AV Graft)
A synthetic tube connects an artery to a vein. Grafts are an option when veins aren't suitable for a fistula.
- Advantages: Ready faster than fistula (2-3 weeks), good for those with small veins
- Watch for: Higher infection risk, may develop clots
Central Venous Catheter
A tube inserted into a large vein in your neck, chest, or leg. Used as a temporary solution while waiting for a fistula or graft to mature.
- Advantages: Can be used immediately
- Disadvantages: Highest infection risk, not recommended for long-term use
Daily Care for Your Access
Proper daily care prevents infections and extends the life of your access:
- Keep it clean: Wash your access site daily with antibacterial soap and water. Pat dry gently.
- Feel the thrill: Check your access several times daily by feeling for a vibration (called a "thrill"). This confirms good blood flow.
- Listen for the bruit: Place your ear near your access—you should hear a whooshing sound. No sound may indicate a problem.
- Protect your access arm: Don't carry heavy bags, wear tight clothing, or sleep on your access arm.
- Never allow: Blood pressure measurements, blood draws, or IV lines in your access arm.
Warning Signs - Seek Immediate Care If You Notice:
- • No thrill or bruit
- • Redness, warmth, or drainage at the access site
- • Fever or chills
- • Swelling in your access arm
- • Numbness or coldness in your fingers
Preventing Infections
Infection is one of the most serious complications of dialysis access. Follow these prevention strategies:
Hand Hygiene
Always wash your hands before touching your access. Ask healthcare providers to do the same before examining your access or starting dialysis.
Clean Environment
Keep your access clean and dry. Cover it when showering until needle sites are fully healed. Change bandages as instructed by your care team.
Sterile Technique
Ensure dialysis staff use sterile technique when accessing your fistula or graft. Don't be afraid to speak up if you have concerns.
Regular Monitoring
Schedule regular check-ups with your vascular access specialist to detect problems early before they become serious.
When Your Access Needs Intervention
Even with excellent care, access problems can develop. Common issues include:
- Stenosis (narrowing): Scar tissue can narrow your access, reducing blood flow. May require angioplasty or stenting.
- Thrombosis (clotting): Blood clots can block your access. Requires immediate declotting procedure.
- Infection: Requires antibiotics and sometimes access removal if severe.
- Steal syndrome: Access takes too much blood from your hand, causing pain and coldness.
