My dad is in last stages of dementia and last week he was hospitalised with yet another infection. After several different antibiotics, dad is still not responding, has not eaten for a week. The hospital has suggested it's now time to withdraw the saline IV and just make dad comfortable. They think tube feeding him is going to be intrusive and not much help to dad. should we just let dad go or insist hospital carry on. Will dad be in pain if they withdraw saline..... So many questions!!!!
