G tube to gravity drainage

If a patient has a G-tube to gravity drainage, then nothing they drink will be absorbed correct? They will get no nutrition at all?
There is some absorption from the stomach, upper GI tractor of some fluids/meds, but that would be limited.In my experience, this is often a measure for comfort for cancer pts, that have substantial GI obstruction/malabsorbtion resulting in intractable vomiting. The tube drains whatever they drink that is not readily absorbed, and to drain excess digestive secretions that would otherwise cause wretching and vomiting. The pt can take fluids for comfort, without the accompanying vomiting.

That is precisely what is going on with this patient. How long can one sustain life at this point?

If someone could answer that they would be a millionaire. An experienced hospice nurse can make determinations based on the patient, the patient's disease process, activity, the existing data, etc... The hospice nurse is the one to ask.

You as a nurse can kind of guesstimate that answer. Leaving the G-tube to gravity is a comfort measure when obstructions become significant...... but know that the comfort to the patient and the family are hugely beneficial that they can take and give sips and not vomit incessantlly.....is comforting...to them.......((HUGS)) to the family....

Normally I think we say 5-7 days if they aren't able to take in liquids. So he can absorb a small amount through his stomach? So this would be a bit longer then? This sweet dearheart has not had vomiting but is obstructed with multiple tumors throughout the small intestines, ileostomy was done in March. He was pouring out around the g tube because so much pressure and obstruction, so they put in a bigger g-tube and voila, it is draining now. We did have it to wall suction. Poor fella!

A couple months at best..likely less than that. We usually hydrate these pts pretty aggressively IV wise too.

as a hospice pt we would not iv hydrate them most likely. We just had a pt with this and it was about 10 dyas . but it was such a comfort to the pt and they were so happy with the freedom it afforded them to be able drink(which they did and insane amount).

I had a relatively "healthy" case that lasted for several weeks. At the time that I cared for him, virtually the only major issues that he had was the incurable ca that was growing faster than he could get it resected, and obstructing. To my understanding, he got very little IVF, but did take in quite bit of fluid that some absorbed in the upper GI. But this pt had a great deal of reserves - most do not.I no longer make predictions as: G-d, fate, karma, mother nature- willmake a liar out of me.
