enteral nutrition  the delivery of nutrients in liquid form directly into the stomach, duodenum, or jejunum.

parenteral nutrition  administration of nutriment intravenously.

total parenteral nutrition  (TPN) intravenous administration, via a central venous catheter, of the total nutrient requirements of a patient with gastrointestinal dysfunction.

Parenteral nutrition

Nutrition supplied intravenously, thus bypassing the patient's digestive tract entirely.

Mentioned in: Electrolyte Supplements, Necrotizing Enterocolitis

parenteral nutrition,

the administration of nutrients by a route other than the alimentary canal, such as subcutaneously, intravenously, intramuscularly, or intradermally. The nutrients, or parenteral fluids, usually consist of physiologic saline solution with glucose, amino acids, electrolytes, vitamins, and medications. They may not be nutritionally complete but maintain fluid and electrolyte balance during the immediate postoperative period and in other conditions, such as shock, coma, malnutrition, and chronic renal and hepatic failures. See also total parenteral nutrition.

parenteral (pren´trl),

adj literally, “aside from the gastrointestinal tract”; not through the alimentary canal (i.e., by subcutaneous, intramuscular, intravenous, or other nongastrointestinal route of administration).

parenteral nutrition,

n the administration of nutrients by a route other than the alimentary canal, such as subcutaneously, intravenously, intramuscularly, or intradermally. The parenteral fluid usually consists of physiologic saline with glucose, amino acids, electrolytes, vitamins, and medications, which are not nutritionally complete but maintain fluid and electrolyte balance.

critical care nutrition

provision of nutritional support for patients in critical care units; usually requires modification of normal nutritional requirements to meet the demands of stress, injury and disease, and to support recovery from these states.

enteral nutrition

see enteral feeding.

intravenous nutrition

see parenteral nutrition (below).

nutrition Labeling and Education Act of 1990

an amendment to the (US) Federal Food, Drug, and Cosmetic Act which defines how foods, claimed to affect disease, are not regulated as drugs.

parenteral nutrition

a technique for meeting a patient's nutritional needs by means of intravenous feeding; sometimes called hyperalimentation, even though it does not provide excessive amounts of nutrients. Nutrition by intravenous feeding may be total parenteral nutrition (TPN) or supplemental. TPN provides all of the carbohydrates, proteins, fats, water, electrolytes, vitamins and minerals needed for the building of tissue, expenditure of energy, and other physiological activities.

total parenteral nutrition

called also TPN; see parenteral nutrition (above).

parenteral

not through the alimentary canal, e.g. by subcutaneous, intramuscular, intrasternal or intravenous injection, e.g. parenteral fluid therapy.

parenteral alimentation

see parenteral nutrition (below).

parenteral hyperalimentation

see parenteral nutrition (below).

parenteral nutrition

the provision of adequate carbohydrate, protein, vitamins, minerals and fluids parenterally to maintain the animal over a relatively long period of several weeks. Called also parenteral alimentation, parenteral hyperalimentation. See also parenteral nutrition.

parenteral therapy

treatment by the parenteral route is limited to those substances that are soluble in a solvent that can be injected into tissues including the bloodstream. The choice of routes may depend on the nature of the vehicle used, e.g. oily preparations are injected into tissues, irritant substances are injected intravenously slowly.

parenteral nutrition

IV feeding, parenteral alimentation The administration of nutrients parenterally, usually IV. See Total parenteral nutrition. Cf Forced feeding.

Patient discussion about parenteral nutrition.

Q. why is it that some women lack parental nutrition?

A. Do you mean breastfeeding? Some women have problem with their nipples, in rare cases the breast tissue isn't developed enough. Sometimes breast surgeries damage the milk ducts. Psychological factors also play a role.
