What is a day in the life like?

Hello to all! I was wondering if any CRNAs could give me a detailed account of what a day is like. I have shadowed several CRNAs, however I did not follow them from preop to post op. Take for example, an open heart case or any type of general surgery, what types of medication do you use to begin with? To maintain? To end? Do most of you intubate and start pressure lines on your patients prior to the procedure?

Any information is greatly appreciated!
