The moral of the story? Depends on who you ask.
i had 3 different "perma caths". the first one i was extremely extremely careful with because i was new at the dialysis thing and had been told to be careful because the catheter could fall out. BALONEY!
I'm taking NO chances with any tube going straight into my heart.
I agree about the catheter that goes into my heart...I don't want to take any chances either. but on the occasion that the dresssing over it has gotten damp we have changed it to a dry one...but I still want to keep that area as dry as possible...I was able to shower with the handheld showerhead and will be able to wash my hair in the kitchen sink
