Tunneled Catheter (Permcath) Insertion for Dialysis
A Reliable Long-Term Dialysis Access Option for Chronic Kidney Disease Patients
What is a Tunneled Catheter (Permcath)?
A Tunneled Catheter, often called a Permcath, is a soft plastic tube placed into a large vein, usually in the neck or chest, to allow for long-term hemodialysis access. It is used when arteriovenous fistulas or grafts are not available or suitable.
Emergency Dialysis: Immediate access needed when fistulas or grafts are not functioning.
Inadequate AV Access: When arteriovenous access fails or is unsuitable.
Limited Access Options: When peritoneal dialysis or AV fistulas are not possible.
Procedure for Tunneled Catheter Insertion
Preparation & Positioning: Patient is positioned lying down, neck or chest exposed, and skin cleaned with antiseptic.
Local Anesthesia: Area is numbed for a pain-free experience.
Catheter Insertion: The catheter is placed into a central vein (usually IJV or subclavian) using a guidewire.
Tunneling: A tunnel is created under the skin where the catheter is threaded to reduce infection risk.
Securing the Catheter: The catheter is stitched and bandaged to prevent movement or infection.
Testing: Blood flow is checked to ensure the catheter works well for dialysis.
Advantages of Tunneled Catheters
Ideal for long-term dialysis access
Lower infection risk compared to non-tunneled catheters
Improved patient comfort and mobility
Reduced chances of catheter dislodgement
Possible Complications
Infection: Proper care is crucial to prevent CRBSIs.
Thrombosis: Blood clots may form, blocking catheter use.
Pneumothorax: Rare lung puncture during insertion.
Bleeding: Minor bleeding may occur during the procedure.
Catheter Displacement: Can lead to dialysis failure if not secured properly.
Catheter Care and Maintenance
Proper care helps maintain catheter function and reduces complications:
Flush catheter regularly with heparinized saline
Keep the exit site clean and dry
Change dressings as instructed by your healthcare provider
Watch for signs of infection: redness, swelling, pain, or discharge
Report any issues with blood flow or catheter discomfort immediately
Conclusion
The Tunneled Catheter (Permcath) is a reliable and safe option for patients who require long-term dialysis access. While it comes with some risks, proper insertion, maintenance, and care can ensure its effectiveness. Always consult with a certified nephrologist or vascular specialist for guidance tailored to your health needs.
