What is parenteral nutrition support?
In some cases, persons undergoing treatment for cancer need total parenteral nutrition (TPN) to help meet their nutritional needs. TPN is a special mixture of glucose, protein, fat, vitamins, and minerals that are given through an IV into the veins. This procedure is also called “intravenous feedings.” TPN provides necessary nutrients when someone is not tolerating food by mouth, not absorbing nutrients in the gut, or needing bowel rest. The TPN solution is usually infused continuously over several hours of the day.
