What is a Catheter?
Catheter (CVC – Central Venous Catheter) is a long, thin and flexible tube inserted into the body through a large vein. It is often used to administer medications, fluids, or blood products, collect blood samples, or perform dialysis. Depending on the intended use, it is placed in different areas, most often in the neck, chest or groin area. Proper placement and care of the CVC reduces the risk of infection and other complications. The use of CVC provides great comfort for patients in long-term treatments or in situations where frequent blood samples need to be taken.
Catheter Use in Dialysis
Central Venous Catheter (CVC) is used as a temporary or permanent method of vascular access for patients requiring dialysis treatment. It provides a flexible and safe way to transfer blood to the dialysis machine and return it.
Catheter (CVC) Placement Areas for Dialysis
Catheter for Dialysis (cvc) is usually placed in large veins in the neck, chest or groin area. While the chest area is generally preferred for permanent use, the groin area is more frequently used for temporary access needs.
Catheter Care
Regular and careful maintenance of the catheter is essential. The catheter exit site should be kept sterile and constantly monitored for signs of potential infection. Additionally, the inside of the catheter can be flushed with heparin solution to prevent obstruction.
Catheter Complications
Possible complications of the catheter used during dialysis include local infection, obstruction, air embolism and catheter dislocation. These risks can be minimized with correct installation techniques and regular maintenance.
Advantages of Catheter
CVC provides rapid vascular access for patients in need of urgent dialysis. It allows starting dialysis treatment immediately, without the waiting period for the fistula or graft creation process.
Frequently Asked Questions About Catheter (CVC)
How long can the dialysis catheter be used?
The dialysis catheter can be designed to be temporary or permanent. Temporary catheters are usually used within a few weeks, while permanent catheters can be used for months or longer.
Is insertion of the catheter painful?
The insertion of the catheter is usually done under local anesthesia, so no pain or discomfort is felt during the procedure. You may feel some slight discomfort after the procedure, but this is usually mild and temporary.
Can I take a bath with a dialysis catheter?
The catheter area should not be exposed to water. Therefore, it is recommended to cover the catheter area with a waterproof material when taking a shower. It is best to follow your doctor or nurse's recommendations.
What are the advantages of a dialysis catheter?
The dialysis catheter provides immediate vascular access, so it is suitable for patients who need urgent dialysis. It is also used as a temporary access method for patients awaiting fistula or grafts.
What are the complications related to the dialysis catheter?
The most common complications include infection, obstruction, catheter dislocation, or air embolism. These risks are minimized with correct installation and maintenance techniques.
What should be done if the catheter becomes blocked?
Catheter obstruction can cause low blood flow rates during dialysis. In case of blockage, you should contact your dialysis team immediately. They may use special solutions or techniques to relieve the blockage.
