Question 1

any other suggestion to stop chyle leak after nephrectomy? have tried mct diet, octreotride with tpn for 5 weeks. still draining 10 liters per week.

Accepted Answer

This is serious.: After all this time on appropriate medical treatment you need to have a discussion with your doctor. The time may be ready for surgery 10 liters a week is a lot to lose. Get to your doctor asap for a discussion of the possible need for surgery.

Question 2

when do you use tpn?

Accepted Answer

Last resort: Typically TPN is used as a last resort for patients who can get nuturion by no other means. Because there are some risks inherent to this method, doctors typically will only use this when they have no other good alternatives.

Question 3

in medicine, what does tpn mean?

Accepted Answer

TPN: TPN = total parenteral nutrition. It is nutrients that are delivered through your vein.

Question 4

what is tpn and when is it given?

Accepted Answer

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).

Question 5

how long will someone stay on tpn?

Accepted Answer

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.

Question 6

what are the complications of  tpn?

Accepted Answer

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.

Question 7

my sister just started tpn. why does she feel full?

Accepted Answer

Good question.: I think the bigger question is why is she on TPN? That likely is related to why she feels full. I suggest you discuss this with her, and if she is willing to allow you to talk with the doctor who is giving her TPN, then discuss the situation with them. She may not want you to know everything, and that is her choice. If so please respect that.

Question 8

what is the osmolarity of tpn?

Accepted Answer

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.

Question 9

how does tpn compare to a glucose iv for nutrition?

Accepted Answer

Much better: Glucose IV is really not nutrition. Nutrition includes balanced protein, carbohydrate, lipid, electrolytes and other ingredients, all included in TPN and often personalized. We use glucose ivs short-term to avoid hypoglycemia that may happen from the body spending the available carbohydrates for energy. That being said, enteral feeding is always better (what goes in the stomach and bowels).

Question 10

is it possible to have chemotherapy and tpn use the same line?

Accepted Answer

Not really: I personally prefer TPN to have its own line, and you will hear that from experienced nurses.  While the substances may not be incompatible, TPN is associated with risk of infection in the line, so should really have its own, dedicated vascular catheter access, in my opinion.  I suppose there could be situations where TPN and chemo have to share a line, but if there's a choice, they shouldn't.
