TPN, or total parenteral nutrition, is a type of IV fluid that provides total nutrition to someone who cannot take any nourishment by mouth. TPN contains sugars, electrolytes, vitamins, proteins, and fats (called lipids), and can supply all of the nutrients that the body needs.
Premature babies often receive TPN while their intestines mature. The TPN will be given through an IV, an umbilical catheter, or a PICC line. When milk feedings are started, the amount of TPN that a baby receives will gradually be tapered down as the milk feedings are increased.
Also Known As: total parenteral nutrition, parenteral nutrition, hyperalimentation
