TPN stands for Total Parenteral Nutrition. … TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve.

Why is TPN given in a central line?

Historically, total parenteral nutrition (TPN) has been administered by the central venous route because of the rapid development of thrombophlebitis when TPN solutions are administered into peripheral veins. … By avoiding central venous catheterization, TPN can be made safer.

What is a central line for nutrition?

Central line. This kind of line is often used for babies and very young children. The catheter is placed into a vein in the neck or chest. This allows nutrients to be delivered close to the large blood vessels of the heart. The catheter has openings (ports) to give nutrition and medicines as needed.
