Dialyysikatetrin

Dialyysikatetri, often referred to as a dialysis catheter, is a medical device used to access a patient's bloodstream for hemodialysis. Hemodialysis is a treatment that removes waste products and excess fluid from the blood when the kidneys are not functioning properly. The catheter provides a way to efficiently and safely withdraw blood from the body and return it after it has been cleansed.

There are several types of dialysis catheters, but they generally consist of two lumens. One lumen is used for drawing blood out of the body, and the other is used for returning the treated blood. These catheters are typically inserted into a large vein, most commonly in the neck (jugular vein), chest (subclavian vein), or groin (femoral vein). The insertion procedure is usually performed by a physician.

Dialysis catheters are often used as a temporary solution for patients who require immediate dialysis or for those awaiting the creation of a more permanent vascular access, such as an arteriovenous fistula or graft. While effective, dialysis catheters carry a risk of complications, including infection, blood clots, and damage to the blood vessel. Proper care and sterile technique are crucial to minimize these risks. Regular monitoring by healthcare professionals is also essential for patients with a dialysis catheter.
