What is the hemodialysis catheter?
Hemodialysis catheter is a tube that is inserted into the body to provide access to the vascular system to perform hemodialysis treatment. Hemodialysis is used to treat people with kidney failure. Using a machine outside the body, the blood is filtered to fulfill a function that fails the kidneys does not serve. This treatment can be used temporarily or permanent, depending on why the patient requires hemodialysis. Many patients receive hemodialysis while waiting for kidney transplantation. The hemodialysis catheter can be inserted into the veins in the groin, chest or neck. The device has two lumens, one that pulls blood from the body to circulate it through the hemodialysis machine, and the one that returns the blood to the body.
Using the catheter hemodialysis is not in fact a preferred method. Centrians may be susceptible to infection, precipitation, separation, and other problems, especially if they are left in place for a long time. If a patient has a catheter installed, it may take only a few weeks to be inYet and in the meantime, the patient must observe careful care instructions to reduce the risk of infection and other complications.
Vascular approach can be ensured for long -term hemodialysis with the help of arteriovenous (AV) fistula in which the artery and vein are connected, or arteriovenous graft in which the tube is inserted to form a connection. However, both procedures require surgery and time, and sometimes it is not a patient in urgent need. Hemodialysis catheter can be used to ensure the necessary approach, while the patient waits for a long -term access option, or when the patient cannot receive AV fistulanebo graft.
When a patient requires a hemodialysis catheter, detailed instructions on how to take care of the site will be provided. This may include a leaflet that deals with how to clean and bandage the catheter and what types of activities the patient can safely participate.
