Stacy Wiegman, PharmD, Pharmacy, answeredTotal parenteral nutrition (TPN), sometimes called intravenous, or IV feeding, is a sterile IV fluid that contains all of the nutritional elements that are needed by the patient. It is intended for people who are unable to absorb nutrients from the gastrointestinal (GI) tract, such as those who have serious infection of the pancreas or intestines, serious burns, some cancers or removal of part of the GI tract. Before starting TPN, the parient should have not received enough nutrition by mouth for seven or more days. TPN is usually given in hospitals, but can be administered at home as well.

Total Parenteral Nutrition, or TPN, is intravenous nutrition infused via a central venous catheter. It usually contains protein, carbohydrate, fat, multivitamin, minerals, and electrolytes needed for daily functioning. Physicians can also add certain other medications such as insulin to meet individual requirements. TPN should only be used when a patient's gastrointestinal (GI) tract is not functioning. Risks associated with TPN include, but are not limited to, infection and GI tract atrophy.
Total parenteral nutrition (TPN) gives a person liquid nutrition (such as protein, carbohydrates, and fats) through a tube (catheter) that is inserted into a vein. In a newborn, the tube may be inserted into the umbilical cord artery.
TPN places nutrients needed for growth and tissue repair directly into the blood, by passing the digestive tract completely.
A person's blood sugar and blood chemicals (such as electrolytes) are monitored while he or she receives this type of nourishment.
