Every day is different, but in general I arrive to the OR between 6-6:30, even though my time isn't 'counted' until 7 to make sure I'm ready for the day. The group I'm with does keep track of hours, but it really doesn't make any difference because I'm paid a salary. If there's something with the procedure or patient that I need to brush up on it gives me time. Otherwise I get ready and chat with the other CRNAs. It's about the only time we see each other because the rest of the day we're each in our own rooms. About the first thing I'll do is go meet with my first patient. Often they are nervous and it helps relax them if they meet me and I develop some rapport with them. Around 7:30 the first case goes to the room, and I either induce general anesthesia, place a regional block, or start sedation. Most of the time I am pretty quiet and just concentrate on what's happening with the patient and the case. sometimes the surgeon likes to chat if things are going as expected. Once the case is finished it's emerge the patient as quickly as possible while maintaining safety. Get to recovery room, give report. Then go see the next patient, assess them and get consent, back to the OR to clean up, and set up for the next case. From the time one patient leaves the OR, and the next comes in is about 15 minutes so you really need to move quickly. I draw up a label my drugs for the next case during the middle of the first case otherwise you are behind. Do that throughout the day, usually get 20 minutes for lunch. We don't do the coffee break thing, but some places will have someone get you out of a 10 minute break morning and afternoon.
I'm telling about this part of the career, because I've work with student's who seemed surprised that:1. there is no set time that you can leave, depends on the OR schedule, it's not shift work, 2. you have to move quickly while remaining completly accurate in what you are doing, 3. it's hard work with few breaks during the day, you will leave tired. 4. you are fairly isolated while you work, I'm the only CRNA in the room and we are independent so I don't see a MDA unless I call one in. 5. your work schedule will effect your entire family, maybe I'll be done to go to the soccor game, or maybe I won't. Cell phones are life savers! 6. you need to be good at getting along with people, because surgeons, patients, etc can be difficult and you need to get done what is needed while hopefully keeping things on an even keel.
I find it very rewarding because every anesthetic is different, and it's a challenge to keep up with the new developments in the field. Like many CRNAs I enjoy the technical skills of intubation, and regional blocks, etc. You need to not require a lot of reassurance and be comfortable thinking for yourself.
