Where Do You Put TPN? Understanding Central and Peripheral Venous Access
•
4 min read
Total Parenteral Nutrition (TPN) is not administered through a standard peripheral IV due to its high concentration, which would severely irritate and damage smaller veins. Instead, TPN requires a central venous catheter (CVC) that delivers the nutrient-rich solution directly into a large, central vein with a high blood flow. The specific location for TPN administration depends on the patient's condition, the anticipated duration of therapy, and the required concentration of the solution.
