Total parenteral nutrition
Total parenteral nutrition (TPN), also known as parenteral nutrition (PN), is a form of nutritional support given completely via the bloodstream, bypassing the gastrointestinal tract. It is used when a patient's digestive system is unable to absorb nutrients due to a variety of medical conditions.
Indications[edit | edit source]
TPN is indicated for patients who cannot maintain adequate nutrition by oral or enteral routes. This includes conditions such as short bowel syndrome, severe Crohn's disease, certain types of cancer, and in some cases of severe malnutrition.
Components[edit | edit source]
The components of TPN typically include protein, carbohydrates, lipids, vitamins and minerals. These are mixed in a sterile environment and then administered via an intravenous line.
Risks[edit | edit source]
While TPN can be life-saving, it also carries risks. These include infection, liver disease, and metabolic complications. Regular monitoring is required to manage these risks.
History[edit | edit source]
The development of TPN as a medical treatment began in the 1960s, and it has since become a standard part of care for patients with certain severe digestive disorders.
