Hi ToriMom,
I had my first picc placed when I was a kid, and while they tried to do it without anything, I ended up having this massive panic attack and basically it was pure chaos. After that I got a dandy little note in my chart saying I needed 'conscious sedation' in order for a picc to be placed.
When doing CS during a picc placement you go to IR because they have all the necessary equipment (monitors and whatnot). I get a mix of versed and some pain management/blocker - this one varies, but the versed is usually a concrete.
When I get rolled into the room (I've usually already been giving a dose of Ativan at this point since I get really freaked out by the whole ordeal) and then they hook me up all the monitors: blood pressure, heart monitors pulsox, etc etc and then the nurse usually chats with me as she pushes a few cc's at a time of versed & pain blocker. Next think I know, I'm waking up in my room and I have a picc in my arm. Sometimes they come in to ultrasound my arm first before or during the hooking up to monitors process.
Then I sleep for the rest of the day.
While, I think, technically you're "awake" during the procedure, you're so loopy you don't care, and then versed has a nifty side effect of making you forget as it wears off.
It's a much easier process for me mentally than getting one placed bedside. It's not the pain that gets me, they're pretty painless once you get the numbing shot, it's all mental.
I hope things go well for you and your daughter! Good luck.
