question: hi, the query i have is that my 75 yr old mother was admitted to hospital last week after a fall. after routine blood tests it was found she was suffering acute renal failure. because of this it was decided to stop all treatment and to let nature take its cause. that was on friday. but then today (monday) we were told that the wrong disicision was made and treatment was started up again. but what id like to know is how much damage has been caused because of this and are we fighting a losing battle.
