A central line is a special type of IV that allows nutrition and medications to be delivered directly into a large vein near your heart.
Why is a central line needed for TPN?
- TPN is a very concentrated medication. It cannot safely be given through a regular IV.
- Large central veins have strong blood flow, which helps dilute the TPN as it enters your bloodstream.
- Central lines are also designed for long-term use and can remain in place for months or even years.
Common types of central lines
- PICC – placed in a vein in the arm
- Tunneled line – placed under the skin and connected to a large vein (often called by brand names such as Hickman®, Broviac®, or Leonard®)
- Implanted port – placed under the skin and accessed with a special needle
- Your provider will determine which type is best for your medical needs.
What this means for you
A central line makes long-term IV nutrition possible and allows you to safely receive TPN at home. With proper education and support from Nutrishare, many patients live active, independent lives.
