When giving Dilaudid into a port because of cancer, saline flush first, then the dilaudid, then a saline flush and then a heparin flush? I used to do it but have forgotten the order in which I did it. I remember using four different needles into the port. I am trying to write a book about my daughter's cancer but wasn't really trying to remember what I did or how over 20 years ago. I want it to be accurate as possible. Please help me in any corrections.
