THE FULL EXPLANATIONCan Lipids Be Given Peripherally for TPN? A Practical Guide to Peripheral Lipid Administration
Yes. Lipids can be given peripherally as part of total parenteral nutrition, usually as a separate lipid emulsion infused through a peripheral venous catheter alongside a dextrose-and-amino-acid solution.
