I believe in assisted suicide. When I worked with alzheimer's patients I did hope there was a way of putting them out of the misery but I would never want that without their consent.
I have seen nurses give them levels of morphine that speeded up the dying process, so instead of dying in six hours they died in two.
Once they stopped getting up and refused to eat we would stop feeding them and giving them water because it more painful for us to give them food once they have stopped. And dehyrdration is a natural pain reliever.
A couple of points here. The risk of aspiration is very high with these patients. That is why I would withhold fluids or food by mouth.
Second, narcotics given for comfort at end of life do not 'speed up' the dying process or 'kill' the patient. I had a link to some research on this, I'll have to see if I can locate it.
Rats. I just did a quick search and there's info from the cancer center at the Cleveland Clinic which backs me up, but that isn't the one I was thinking of.
Morphine has no upper dose limit; it can be titrated to pain. It also serves to ease respiratory distress and 'air hunger' and lowers the workload on the heart.
I'll keep searching for the study.
