Tunneled catheter insertion
Tunneled dialysis catheter placements inserts a tube or catheter under the skin and into a major vein. The tube has 2 openings. The blood leaves the body through the red opening. It is filtered and cleaned through dialysis. The cleaned blood returns through the blue opening.
What are the reasons for the procedure?
This procedure is performed to enable a speedy access to blood flow to do dialysis. Dialysis is a process that filters and cleans the blood when the kidneys are no longer able to do on their own.
Individuals who have this catheter don't need to have multiple needle sticks at each dialysis visit. This drops the risk of infection and damage.
Procedure
An ultrasound and x-rays utilizing contrast material will be utilized to assist with finding the vein. It will assist with placing the catheters in place.
A tiny cut will be made in the lower neck. The specialist will get to the jugular vein in the neck with a needle and pass a small guidewire into the vein. The guidewire will be passed to a larger blood vessel known as the vena cava.
A second cut will be made in the chest underneath the first cut. A passage will be made simply under the skin between the first and second cuts. The flexible dialysis catheter is then passed from the second cut, through the tunnel, to the first incision site. This is where it is passed over the guidewire and into its last position. The guidewire is taken out from the veins. The other end of the catheter will stay outside the body, stretching out through the second cut. The specialist will ensure that blood is flowing in the catheter.
Right catheter placement can be checked with x-rays. The catheter will be secured with stitches. Some catheters have a cuff that sits in the tunnel under the skin. This cuff helps keep the tube secure and liberated from infection. The main entry point will be closed. It might be closed with stitches, tape, or a sort of clinical glue. The second cut will be stitched around the catheter to assist it stay in place. Both areas will be bandaged.
