Even after explaining it in detail to my 1st French surgeon (I was awake at the time and not in any urgent situation) when he finally operated on me I woke up with an ostomy bag stuck to my abdomen and no cath in my stoma!
So much for them understanding detailed explinations.
Somewhere along the line you must explain that in case of prolonged unconsciousness to place an indwelling cath into the stoma and leave it there...if not they may never figure it out.
