You have a central venous catheter. This is a tube that goes into a vein in your chest. It will help carry nutrients and medicine into your body. It will also be used to take blood when you need to have blood tests.
These catheters are used when people need medical treatment over a long period of time.
Dressings are special bandages that block germs and keep your catheter site dry and clean. You will learn how to change your dressing. You should change the dressing about once a week. You will need to change it sooner if it becomes loose or gets wet or dirty. After some practice, it will get easier. A friend, family member, caregiver, or your doctor may be able to help you.
It is okay to take showers and baths 7 -10 days after your catheter was put in place. When you do, make sure the dressings are secure and your catheter site is staying dry. Do not let the catheter site go under water if you are soaking in the bathtub.
