Topic: Tests & Procedures

This handout was written to answer some of the questions most often asked about a tunneled silicone central venous catheter. Feel free to ask your doctor or nurse to go over any information you do not understand.

A tunneled central venous catheter is a special type of hollow tube that is placed in your child’s chest. It may also be called a “Broviac” or “Hickman” catheter or a “CV line.” The tunneled catheter is usually placed in surgery. A doctor will discuss this with you before surgery. The catheter is placed in a large vein and can be used for:
• Giving medicines
• Providing parenteral (IV) nutrition
• Sampling blood
A special type of dressing (bandage) is placed over your child’s catheter. This dressing is changed regularly. An injection cap is placed on the end of the catheter. This cap helps to keep infection out of your child’s catheter. This cap is changed regularly. A medicine called heparin is injected into the injection cap daily when the line (catheter) is not being used. This helps keep the catheter free from blockage.

Nurses will teach you:
• how to change the dressing
• how to change the injection cap
• how to inject heparin
• problems that can occur with a tunneled catheter
• ways to prevent complications

Once your child has completed his or her therapy, your doctor will decide when to remove the catheter. With the catheter, your child will not need to have as many needlesticks. At times it may be necessary to draw blood from a vein. The information contained in this handout is for general information only and is not to be considered complete. For specific information about tunneled silicone central venous catheter, please ask your doctor.
