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
