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

Frequently Asked Questions About Catheter (CVC)

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.

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.

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.

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.

The most common complications include infection, obstruction, catheter dislocation, or air embolism. These risks are minimized with correct installation and maintenance techniques.

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.
