Until...: A patient stays on TPN until they are able to meet their nutritional requirement by eating and any deficit has been made up. Or, until the gut can be used again via a tube placed in the gut, if the patient cannot eat for other reasons.

Intestine failure: Tpn is the primary therapy for intestinal failure - a condition that exists when your intestine cannot provide enough nutrition and fluid to support life. You may be malnourished or dehydrated and require TPN for a short time. However, in certain situations, TPN can be required long term and may be permanent. In those instances, you may consider intestine transplantation.

IV nutrition: Tpn stands for total parenteral nutrition. Enteral means that the GI tract is used (the patient is eating or tube feeds are being given). Parenteral means that the intravenous route is being used instead. Tpn is used when it's not safe to used the GI tract (for instance, when there's a bowel obstruction) or when the GI tract isn't functioning properly (e.g. Short bowel syndrome).

Numerous. : Total parenteral nutrition (TPN) is a life-saving tool for patients that are unable to tolerate nutrition via their intestinal tract. Unfortunately, it comes with many potential side effects. Most notably is infection. Tpn is delivered intravenously and thus, the IV catheter is a route for blood stream infection. Other problems are high blood sugar, fatty liver and imbalances in electrolytes.

Dr. Hernani Cualing

Solutes dissolved: Osmolarity in total parenteral nutrition if i am correctly reading your mind refers to a formula result when dextrose is combined with amino acids and ionic salts,the formula being a standard. The reason you need the osmolarity number is to prevent giving above athreshold that predispose to thrombophlebitis or painful swelling of intravenous route or at least minimize that complication.

TPN: Total Parenteral Nutrition (TPN) is most often given when you are having problems with eating so you have intravenous feeding. There must be something wrong with your TPN dosing and that requires immediate care by your doctor. Do not wait but contact him/her right now!
