Hi. My dad has just been admitted to hospital with acute kidney failure. he has vascular dementia. He is far from happy there and is agitated about having a drip/catheter in. if her were left alone he would pull them out. The hospital say that they are going to carry out an emergency dialysis (he has not needed this before) in the early hours of the morning: I think they may have to sedate him for this. They do not know if this will be a one off or not. Does any one have experience of treating someone who now has quite advanced dementia with dialysis? I do not know whether dad would tolerate it and query how it would effect his quality of life. I am worried that if he does not have too long left, we should make it as pleasant and comfortable as possilbe. Dialysis will not provide a cure just prolong matters.i don't want to play god with dad's life but I know if he were well he would not want to prolong things for the sake of it.
