[[File:Patient lying in hospital bed in intensive care unit in Germany in 2015.jpg|thumb|This patient of an [[intensive care unit]] of a German hospital could not eat due to a prior surgical operation of the [[Abdomen|abdominal region]] which was complicated by a severe [[sepsis]]. He received [[antibiotics]], parenteral nutrition and pain killers via automated injection employing [[syringe driver]]s (background, right).]] 
[[Parenteral nutrition]] is the act of providing required nutrients to a person through an intravenous line. This is used in people who are unable to get nutrients normally, by [[eating]] and [[digestion|digesting]] food. A person receiving parenteral nutrition will be given an intravenous solution which may contain [[salt (chemistry)|salt]]s, [[dextrose]], [[amino acid]]s, [[lipid]]s and [[vitamin]]s. The exact formulation of a parenteral nutrition used will depend on the specific nutritional needs of the person it is being given to. If a person is only receiving nutrition intravenously, it is called total parenteral nutrition (TPN), whereas if a person is only receiving some of their nutrition intravenously it is called partial parenteral nutrition (or supplemental parenteral nutrition).<ref>{{cite book |last1=Halter |first1=Jeffrey B. |last2=Ouslander |first2=Joseph G. |last3=Studenski |first3=Stephanie |last4=High |first4=Kevin P. |last5=Asthana |first5=Sanjay |last6=Supiano |first6=Mark A. |last7=Ritchie |first7=Christine |editor1-last=Edmonson |editor1-first=Karen G. |editor2-last=Davis |editor2-first=Kim J. |title=Hazzard's geriatric medicine and gerontology |publisher=McGraw Hill |location=New York |isbn=978-0-07-183345-5 |edition=Seventh |chapter=Chapter 35|date=23 December 2016 }}</ref>
