Central venous catheter
A central venous catheter (CVC) is a thin, flexible tube (catheter) that is placed into a large vein above the heart. It may be inserted through a vein in the neck, chest or arm. It’s also called a central venous line or central line. Some catheters have 2 or 3 tubes (called double or triple lumen catheters). This lets you receive more than 1 treatment at once. Depending on the type of catheter, it may be left in place for weeks, months or years.
Why a central venous catheter is used @(Model.HeadingTag)>
You may have a CVC placed for one or more reasons. A CVC can be used to:
- give chemotherapy drugs and other medicines
- give intravenous (IV) fluids and
- give blood and platelet transfusions
- take blood samples
A CVC reduces the number of injections and needle sticks you will need. A CVC can also:
- lessen soreness from IV therapy
- prevent the burning feeling sometimes felt when getting drugs by other IV methods
- prevent the inflammation and scarring that can happen in a vein after many needle sticks
- increase comfort and lessen anxiety for people who often need IV therapy and blood samples taken
Types of CVC @(Model.HeadingTag)>
Three common types of CVC are a tunnelled central venous catheter, a peripherally inserted central catheter (PICC) and a subcutaneous (implanted) port.
Your doctor will recommend the type of CVC you should have based on your situation and how long the CVC may be needed. A CVC can be inserted either in a special x-ray department with local freezing and light sedation or in the operating room using general anesthetic (you will asleep).
Caring for a CVC @(Model.HeadingTag)>
Central venous catheters need special care. They may need regular cleaning or sterile dressing changes. CVCs need to be flushed regularly with a special sterile solution to keep them from getting blocked when not in use. Your health care team will give you information and teach you about caring for a CVC before you go home.
Special considerations for children @(Model.HeadingTag)>
Preparing children before a test or procedure can lower anxiety, increase cooperation and help them develop coping skills. Preparation includes explaining to children what will happen during the test, such as what they will see, feel and hear.
Preparing a child for a CVC depends on the age and experience of the child. It is important not to tell children that having a CVC means they will never have to be poked by a needle again, since they may still need needle sticks for some blood tests.
