What is TPN?

Total Parenteral Nutrition (TPN) is a method of providing a sterile form of liquid nutrients into the blood through an intravenous (IV) catheter. It contains nutrients your body would normally get from food, such as protein, carbohydrates, fats, vitamins, minerals, and water.

Who needs TPN?

Certain diseases, surgeries, and injuries can cause problems with the normal process of digestion and absorption which occurs within the gastrointestinal tract. The stomach or bowel may not be working normally or a person may have had surgery to remove part or all of these organs. Because TPN is given into the blood, it bypasses the gastrointestinal tract. TPN is only used if other methods to feed into the gastrointestinal tract have failed or are not possible. But in people who need TPN, it can be given for as long as it is needed. People can live very well on TPN for many, many years. It can be given to people of all ages, including infants and children as well as adults.
