Palliative Care and artificial hydration - patient comfort concerns?

[Scooter]

Requesting considered opinions regarding the practice of discontinuing IV hydration in short-term terminal patients. Are there meaningful data to support the apparent Hospice-culture dogma that the patient experiences no discomfort, etc.? Anyone with an opinion based on real professional experience? There seems to be much conflicting argument, and a lot of literature to wade through, and I am not fluent in your esteemed discipline, and have little time to educate myself. I have a loved-one destined for Hospice Care if she survives this night in hospital, and I am apprehensive about their stated policy, as I understand it, of "no IVs unless a physician outside their organization orders it". Apparently, even analgesia at this facility is not administered parenterally, which strikes me as a difficult limitation, but I admit that I am not versed in these things. I am only concerned about patient-comfort, not medical intervention or prolonging life... I am resigned to the fact that the patient is terminal. She cannot communicate in any way, so I am deeply anxious at the spectre of discomfort from dehydration- not necessarily thirst alone, but also the possibility of some unrecognizable agitation and other effects that seem to be well-documented in non-terminal patients. I am not requesting medical advice specific to this or any patient-case, of course, and will not consider any responses as such. I would be deeply appreciative to any med-pro or academic who might take a moment to enlighten me a bit. Please.
