Hemodialysis catheter

Hemodialysis catheter is a type of catheter used for hemodialysis, a process that cleans and filters the blood for individuals whose kidneys are not functioning properly.

Overview

A hemodialysis catheter is a special tube inserted into a large vein in the neck, chest, or groin to allow access to the bloodstream for hemodialysis treatment. The catheter has two lumens or channels. One lumen is used to carry blood from the patient to the dialysis machine, while the other returns the filtered blood from the machine to the patient.

Types of Hemodialysis Catheters

There are two types of hemodialysis catheters: temporary and permanent.

• Temporary catheters are used for short-term dialysis treatment and are usually inserted into the jugular vein in the neck.
• Permanent catheters are used for long-term treatment and are typically placed in the chest. They have a cuff that helps to hold the catheter in place and prevents infection.

Procedure

The procedure to insert a hemodialysis catheter involves local anesthesia and is usually performed in a hospital or dialysis center. The catheter is inserted into a large vein and advanced until its tip reaches the right atrium of the heart. The other end of the catheter is either left free-flowing (in temporary catheters) or attached to a dialysis machine (in permanent catheters).

Risks and Complications

Like any medical procedure, the use of a hemodialysis catheter carries some risks. These may include infection, bleeding, and clotting. In some cases, the catheter may also cause damage to the vein. It is important for patients to report any signs of infection or other complications to their healthcare provider immediately.
