Hey There,
First off. Let me say, "I am real sorry about the shape that your dear mother is in." I have a port in my chest. I agree with you on what you said. About how there was no reason for your mother to have it get infected. It makes one wonder, that if sanitary conditions were followed correctly, how could this have happened to her?
As far as the bad attitudes on those few nurses and that Dr. Doom goes. Well, I hope that you have reported them and asked for a 'gig head' to talk to about it all. Then, I'd request (if not offered to you already) a new, excellent Dr. for your mother. I'd also want to read what they said caused the infection on your mother. But, that's me. I would not take this type of treatment at all. We're talking about the life of your dear mother here.
I pray that she comes out of this as she needs to. Please, try and hang in there. Do what you must do. Take care of yourself, too. Hugs and best wishes to you and your mother. May God Bless, and look over both of ya'all. As well as your other loved ones, friend.
My Very Best to You,
Rosie
