Tunneled Dialysis Catheters: Your Temporary Access Solution

Understanding when catheters are needed, how to care for them, and planning for permanent access.

A tunneled dialysis catheter provides immediate access for hemodialysis when a fistula or graft isn't ready or available. While not ideal for long-term use, catheters serve as an important bridge to permanent access.

When Is a Catheter Needed?

Emergency Dialysis

When dialysis is needed urgently and no permanent access exists.

Fistula Maturing

While waiting 2-4 months for a new fistula to become usable.

Access Problems

When your fistula or graft needs time to heal after intervention.

No Other Options

Some patients with exhausted access options rely on catheters long-term.

Catheter Care Is Critical

DO

  • Keep the exit site clean and dry
  • Change dressing as instructed
  • Secure the catheter to prevent pulling
  • Report any problems immediately

DON'T

  • Get the catheter wet (no swimming, careful showers)
  • Let anyone access it except trained staff
  • Ignore signs of infection
  • Pull or tug on the catheter

Warning Signs

Call Immediately If You Notice:

Fever or chills
Redness, swelling, or pus at exit site
Catheter comes out or moves
Bleeding from the site

Planning for Permanent Access

Catheters have higher infection rates than fistulas or grafts. While you have a catheter, work with your care team to plan for permanent access:

Fistula
Best option—lowest infection risk, longest lasting
Graft
Good alternative if fistula isn't possible
Catheter
Last resort—highest complication rate
