🚨 Dialysis Port? Fistula? Graft? Catheter? Know the Difference! 🩸🫘
Many people say, “dialysis port,” but there are actually different names and types of dialysis access. For people on hemodialysis, this access is their lifeline because it allows blood to go to the dialysis machine, get cleaned, and return safely back to the body.
But not all dialysis access are the same. Some are meant for long-term use, while others are temporary.
🔹 AV Fistula
Often called a fistula. This is created by connecting an artery and a vein, usually in the arm. It may take weeks to months to mature, but with proper care, it can last many years and is often preferred.
Care tips: Check daily for the thrill/vibration, keep it clean, avoid blood pressure or blood draws on that arm, avoid tight clothing, and report swelling, redness, pain, bleeding, or no thrill.
🔹 AV Graft
Often called a graft. This uses a soft artificial tube to connect an artery and a vein. It can usually be used sooner than a fistula, often within weeks, and may last months to years, depending on the patient and complications.
Care tips: Check for the thrill daily, keep the site clean, avoid pressure on the access arm, rotate needle sites during dialysis, and report warmth, drainage, swelling, fever, prolonged bleeding, or no thrill.
🔹 Temporary Dialysis Catheter
Also called a non-tunneled catheter or Quinton catheter. This is usually placed in the neck or groin when dialysis must start quickly. It is meant for short-term use, often days to a couple of weeks, because infection risk is higher.
Care tips: Keep the dressing clean, dry, and intact. Do not pull or bend the catheter. Do not remove caps or clamps unless trained. Report fever, chills, bleeding, pain, loose dressing, or drainage right away.
🔹 PermCath / Tunneled Dialysis Catheter
Many patients call this a chest port, but medically it is a catheter. It is placed under the skin before entering a large vein and may be used for weeks to months, sometimes longer, while waiting for a fistula or graft to be ready.
Care tips: Keep the dressing dry and secure, avoid swimming or soaking, protect it from pulling, and report redness, drainage, fever, chills, pain, bleeding, or catheter movement.
🔹 Peritoneal Dialysis Catheter
This is a soft tube placed in the abdomen for peritoneal dialysis, where dialysis fluid goes in and out of the belly instead of blood going through a machine. With careful care, it may last for years.
Care tips: Wash hands before touching it, keep the exit site clean and dry, secure the catheter to avoid pulling, follow sterile technique, and report cloudy fluid, belly pain, fever, redness, or drainage.
⚠️ When should you call the dialysis team right away?
Call immediately if there is fever, chills, redness, swelling, drainage, severe pain, uncontrolled bleeding, prolonged bleeding after dialysis, a loose catheter, catheter cap problems, or no thrill/vibration in a fistula or graft.
💡 Simple reminder:
The best access depends on the patient’s body and medical condition. But in general, fistulas usually last the longest, grafts are another long-term option, and catheters are often used when dialysis must start quickly or when other access is not available.
Knowing the correct name of your dialysis access can help you communicate better with nurses, doctors, dialysis centers, and emergency staff. 🩺
