Thanks for the suggestions, OsloGirl.
Here's some things I had come up with on my own:
2)Extra laryngyscope bulbs and batteries - lithium, so they're MRI-compatable.
3)One of those small, squat LED-flashlights to provide extra light in case of a power failure, but also to transilluminate a child's hand/arm if I can't get a line in.
4)Tape measurer (I've had that one since my days in dialysis)
5)My Leatherman tool
6)Cuff pressure gauges for my ETT
7)A couple of #3 ETT adapters (is that the right size...I can't remember if that's the one that universally fits)
Y'all get the idea. Things that should be there, but often aren't.
I will have everything OsloGirl suggested and then some...my Blackberry has Epocrates, and I'm about to download a couple of other programs I've heard are helpful. Our peds instructor suggested a good one yesterday.
I just hate the thought of being unprepared for any eventuality. I know it'll happen, and I'll get better at predicting what I'll need with experience, but I want to try and be as ready as I can be, now, going in.
