Total Parenteral Nutrition
Total Parenteral Nutrition (TPN) is a liquid food that goes directly into the blood stream, by passing the digestive tract.
Total = "Complete." The solution contains most of the components of a well-balanced diet: protein, vitamins, minerals, salts, sugar, fats and water.
Parenteral = Outside the digestive tract. To feed through the veins.
Nutrition = Foods and fluids which provide nutrients. Nutrients are substances essential to life and health. They are the building blocks for new tissue and the chemicals that support our vital body functions.
Why is TPN Used?
- To provide "rest" to the gastrointestinal system, for instance following surgery or radiation therapy or when vomiting prevents eating.
- When there is a disease or blockage of the small bowel or other digestive organs.
- When a portion of the bowel has been removed.
TPN can replace all of the food you have been eating. In some cases you may be permitted to eat and drink while receiving TPN. In these cases your physician and/or dietitian will review your diet with you.
