TPN

Total parenteral nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. Fluids are given into a vein to provide most of the nutrients the body needs. The method is used when a person cannot or should not receive feedings or fluids by mouth.

Indications

TPN is used when individuals cannot consume food or fluids by mouth, or when the digestive system is not functioning properly. This can occur in conditions such as Crohn's disease, short bowel syndrome, cancer, and pancreatitis.

Procedure

TPN is delivered through a central venous catheter (CVC), which is inserted into a large vein in the chest or arm. The solution is typically composed of glucose, amino acids, lipids, vitamins, and minerals.

Risks

There are several risks associated with TPN, including infection, blood clots, and liver disease. Long-term use can also lead to bone and muscle loss.
