HOW IS TPN GIVEN? An
Where is a TPN placed?
First, TPN is administered through a needle or catheter that is placed in a large vein that goes directly to the heart called a central venous catheter. Since the central venous catheter needs to remain in place to prevent further complications, TPN must be administered in a clean and sterile environment.
Why does TPN have to go through 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.
