Dialysis Access Catheters

When are Dialysis Access Catheters Used?

Doctors may recommend a dialysis access catheter in several situations:

• Immediate need for dialysis: If you have sudden kidney failure and need dialysis right away, a CVC can be placed quickly to begin treatment.
• Waiting for fistula or graft maturation: Creating a fistula or graft, the preferred access methods for hemodialysis, requires minor surgery and time for healing before they can be used. A catheter can provide temporary access while you wait.
• Not suitable for fistula or graft: If your veins are not healthy enough for fistula or graft creation, a catheter may be your only option for dialysis access.

Benefits

• Quick placement: CVCs can be inserted quickly in a medical setting.
• Less invasive than surgery: Catheter placement is a less invasive procedure compared to fistula or graft surgery.
• Temporary or long-term use: Catheters can be used for short-term needs or for longer periods if necessary.

Risks

• Infection: Catheters are a higher risk for infection than fistulas or grafts. Proper care is essential to minimize this risk.
• Blood clots: Catheters can increase the risk of blood clots.
• Blood vessel damage: Long-term use of catheters can damage veins, limiting future use of other access methods.

Caring for Your Dialysis Access Catheter

Maintaining proper care of your dialysis access catheter is crucial to prevent infection and ensure its proper function. Here are some key points:

• Cleaning: Regularly clean the exit site (where the catheter exits the skin) with a disinfectant solution as instructed by your healthcare provider.
• Dressing: Keep the exit site covered with a sterile dressing to prevent dirt and germs from entering.
• Showers: You can shower with a catheter, but avoid baths and swimming pools which can harbor bacteria.
• Disconnecting: Never disconnect the catheter yourself. Always have a trained healthcare professional handle disconnections and reconnections.
• Signs of infection: Watch for signs of infection around the exit site, such as redness, swelling, or pus. Report any concerns to your doctor immediately.

Conclusion

Dialysis access catheters provide a vital lifeline for people with kidney failure undergoing hemodialysis. While they offer advantages like quick placement and less invasiveness, they come with potential risks like infection and blood clots. Understanding the benefits, risks, and proper care procedures is essential for patients with dialysis access catheters.
