Parenteral nutrition (PN) is feeding a person intravenously, bypassing the usual process of eating and digestion. The person receives nutritional formulae that contain nutrients such as glucose, amino acids, lipids and added vitamins and dietary minerals. It is called total parenteral nutrition (TPN) or total nutrient admixture (TNA) when no significant nutrition is obtained by other routes. It may be called total peripheral nutrition (also TPN) when administered through vein access in a limb, rather than through a central port in body.

Famous quotes containing the word nutrition:
“Men have their own questions, and they differ from those of mothers. New mothers are more interested in nutrition and vulnerability to illness while fathers tend to ask about when they can take their babies out of the house or how much sleep babies really need.”
—Kyle D. Pruett (20th century)
