If your dialysis access isn’t working, it’s completely understandable to feel anxious. Your fistula, graft, or catheter is essential to safe and effective dialysis. When something feels “off,” you may wonder: Is this an emergency—or should I call my doctor?
At Northstar Vascular Surgery Center of Texas, we help patients protect their access health and avoid unnecessary ER visits. This guide explains when to seek emergency care and when your vascular specialist can safely see you in-office.
Important: If you ever feel unsafe, very unwell, or unsure, it is always best to seek care right away by calling 911 or going to the nearest emergency room.
When to Go to the Emergency Room Immediately
Some dialysis access symptoms require urgent emergency care, even if they appear suddenly or seem mild at first. Quick action can prevent serious complications such as infection, clotting, or rupture.
Go to the ER immediately or call 911 if you experience:
- Severe or uncontrolled bleeding (lasting more than 10 minutes with firm pressure)
- Sudden severe pain, fever, or major swelling
- Pus, drainage, or foul odor from the access site
- Symptoms of shock, such as dizziness, weakness, rapid heartbeat, or difficulty breathing
These symptoms may indicate a clot, infection, or structural damage that requires emergency treatment.
“Severe bleeding, no buzz, or sudden pain in your access should always be treated as an emergency.”
To better understand dialysis emergencies, talk with your care team and review trusted resources such as the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
When to Call Your Doctor or Vascular Specialist
Not every access change requires a trip to the ER. Some symptoms should be evaluated quickly, but can often be treated the same day in an outpatient vascular center like ours.
Call your vascular specialist promptly if you notice:
- Weaker thrill or reduced blood flow compared to your normal baseline
- Loss of thrill or bruit (no buzzing or sound when you touch your access)
- Mild redness, warmth, or irritation around your access
- Difficulty with needle placement during dialysis, especially if it happens more than once
- Small changes in skin color or temperature in your access arm
- Persistent bleeding after dialysis that is slower than usual to stop
These may be early signs of narrowing, partial blockage, or a mild infection. Early treatment often prevents hospitalization and keeps your access working safely.

Frequently Asked Questions
How do I know if my dialysis access issue is an emergency?
Go to the ER if you have severe bleeding, no thrill, fever, pus, major swelling, or sudden severe pain in or around your access.
When should I call my vascular specialist instead of going to the ER?
Call your doctor for a weak thrill, mild redness or warmth, needle placement problems, small color changes, or prolonged bleeding after dialysis.
Should I go to the ER if my fistula stops buzzing?
Yes. If the buzz or vibration suddenly disappears, it may mean a clot or blockage and needs emergency evaluation.
