RATTER.....OK....well let us look at the "bigger picture."
Aged 88...Altzheimers and what would appear to be advanced CCF (legs swollen like treetrunks), peeing all over the place, which presumably has been stopped by stopping the diuretics.
What does the future hold?
Can we cure her Altzheimers?........NO
Are we likely to cure her CCF........NO
Are we certain that her leg pains have anything to do with the oedema?......NO
I would suggest that at best her life should be made more comfortable even if it is shortened.
A catheter would only exacerbate an difficult situation.
Diuretics might, just might improve her oedema, but make her pee all over the place. Yes you could use diapers, but in my opinion stopping the diuretcs would be the answer.
Yes.....this is a medical decision and yes she should have talked it over with the GP........but she didn't......she came onto AB for reasons of her own.
