Pronounced (peh-RIH-feh-rul VEE-nus KA-theh-ter) • A peripheral venous catheter is a small, flexible tube that a nurse will place into a vein in your arm or hand. Many people call it an IV (intravenous) line. Why do I need an IV? You will usually need an IV to get chemotherapy, fluids, other medicines, or blood products. What happens when I get an IV? • Before choosing a vein, the nurse will talk to you about any past injuries, planned or past surgeries, or medical devices you may have to help choose the safest vein to use. • Usually, the nurse will try to place your IV in one of the veins in your forearm. It is important for your nurse to start with veins closer to the end of your arm. • Your nurse will try not to place your IV in the bend of your elbow or wrist to prevent movement that could lead to irritation. • After finding the best vein, the nurse will clean the area. • Then, the nurse will use a special needle with clear, plastic tubing around it called a cannula. The needle will be inserted into your vein and then removed, leaving only the plastic cannula inside the vein. What if the nurse has a hard time finding a good vein? Sometimes, it can be hard to put your IV into a vein. • If, after 4 total tries, your nurses cannot place the IV, they will work with your cancer care team to find another option, such as a long-lasting type of IV. How do I prepare for my appointment? Keeping your veins healthy can make it easier to get your IV. The best ways to do this are: • Drink more water/ non-caffeinated fluids the days before your appointment. (Not the morning of appointment) • Dress warmly • Wear loose, comfy clothing Remember If you do not get your IV treatment after the IV is placed, ask your care team to remove your IV before you leave Dana-Farber. If you leave with your IV by mistake, do not try to remove it yourself. Contact your care team for instructions. Call your care team if you notice any redness or swelling around the IV site after your visit. This teaching sheet is for informational purposes only.
