Dear germ79,
I have a port-a-cath. Mine just turned 6 a few weeks back. Normally they don't get so old. Mine is in such good condition, because my mother always access me.
I don't think a port only for blood transfusions is a good idea. Although I understand your daughter's fear, because I was little once too. I really should recommend you to use numbing cream called Emla always and forever!!!
Be sure that only a well educationated and real doc does the needle inserting stuff!!! I don't want your daughter through such hell as I have.
My poarents has been chosen to use my feet for 4 or 6 years. It was very painful - we didn't use Emla at that time - but the veins in my arms and hands recover.
I'm glad you learnt so much from this forum and us. Also I've been here now for a year
Keep reading AND keep posting!!!
Warmest wishes, Dore
