I'm currently in my 5th week of orientation in a trauma ICU. I LOVE it!! It is very challenging, but I agree, make sure you get trained well!!! I ask hundreds of questions every day. I carry a notebook and write down the essentials (for example: things to do/know for an ischemic stroke, how to zero an a-line, what the diff vent setting mean). We get a lot of MVC pts, neuro - stroke, DKA, respiratory failure, some cardiac - but typically it is in conjunction with something else. A-lines, vents, ventriculostomies (<- this was very new to me). Drips - Levo, Neo, Vasopressin, Propofol, Dopamine, Dobutamie, Epi... my preceptor quizzes me everyday on the MAX dose of each, the indication, adverse reactions, etc. Hope this helps!
