Hi there! As an ER RN who went to ICU expressly to get the necessary experience for CRNA school, I hear what you are saying. Although I have REALLY enjoyed the critical care, I have absolutely hated the "politics" of the unit.

I work in a large general ICU which does everything, so while the learning opportunities have been fantastic, the staff is old and crotchety and honestly, down-right evil.

I could expand on that but why dwell on the negative. The truth is that you are there for an express purpose and that is to learn what you need to know. So I put my head down, kept asking for the sickest patients so I'd get great experience, and concentrated on obtaining all my certifications (ICP, CVVH, CV, IABP, CCRN, etc) ASAP and then on getting into school. Honestly, I have been there for almost 2 years now and am leaving in 2 short months to start CRNA school @ OHSU and am COUNTING DOWN THE DAYS!!!

So I am rambling, now, but my point is...hang in there! Just remember why you are there and focus on the great learning experiences that you are presented w/ every day. If you keep your eye on the prize you will be there before you know it! If nothing else, working somewhere you hate keeps you focused on your goals. I mean, be honest, if you loved it there you would be complacent and ambivalent about pursuing a grueling graduate regime. Call me sick but I think it has been a great motivation for me!
P.S. Since I got into school I have been working a shift in the ER once a week...just to hang out w/ the nice people (staff, not patients) and to remind myself that it sucks there too most of the time. The variety helps with the short-timers syndrome.
