Catheter (CVC)

Anasayfa → Catheter (CVC)

What is a Catheter?

A catheter (CVC – Central Venous Catheter) is a long, thin and flexible tube that is inserted into the body through a large vein. It is usually used for the administration of medicines, fluids or blood products, for taking blood samples or for dialysis procedures. Depending on the intended use, it is placed in different areas, often in the neck, chest or groin. Proper placement and care of the CVC reduces the risk of infection and other complications. In long-term treatments or when frequent blood sampling is required, the use of a CVC provides great comfort for patients.

Catheter Use in Dialysis

A Central Venous Catheter (CVC) is used as a temporary or permanent vascular access method for patients who need dialysis treatment. It provides a flexible and safe way to transfer blood to and from the dialysis machine.

Catheter for Dialysis (CVC) Placement Sites

Catheters for Dialysis (cvc) are usually inserted into large veins in the neck, chest or groin area. The chest is usually preferred for permanent use, while the groin is more commonly used for temporary access needs.

Catheter Care

Regular and careful catheter care is essential. The catheter exit site should be kept sterile and constantly monitored for signs of potential infection. The catheter can also be flushed with heparin solution to prevent blockage.

Catheter Complications

Possible complications of catheters used during dialysis include local infection, obstruction, air embolism and catheter dislodgement. These risks can be minimized with proper insertion techniques and regular maintenance.

Advantages of the catheter

CVC provides rapid vascular access for patients in urgent need of dialysis. It allows dialysis treatment to be started immediately without the waiting time of the fistula or graft creation process.

How long can a dialysis catheter be used?

A 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.

Frequently Asked Questions About Catheter (CVC)

The insertion of the catheter is usually done under local anesthesia, so there is no pain or discomfort during the procedure. There may be some mild discomfort after the procedure, but this is usually mild and temporary.

The catheter site should not be exposed to water. Therefore, it is recommended to cover the catheter site with a waterproof material when showering. It is best to follow the recommendations of your doctor or nurse.

A dialysis catheter provides immediate vascular access and is therefore suitable for patients in urgent need of dialysis. It is also used as a temporary access method for patients awaiting a fistula or graft.

The most common complications include infection, obstruction, catheter dislodgement or air embolism. These risks are minimized by correct placement and care techniques.

Catheter blockage can cause low blood flow rates during dialysis. In case of a blockage, you should contact your dialysis team immediately. They may use special solutions or techniques to clear the blockage.
