I work in ICU in England, i'm sure things here are similar if not behind the times! to our US counterparts. I eventually had the guts to go to ICU two and a half years ago, following acute Cardiology for three and a half years, but i won't bore you to death with the minor details of my career!!! I'm sure I had the same trepidations as you did, but with an experienced team around you, you will be supported as much as you need. Never, ever be afraid to ask questions of doctors or nurses, tip- don't ask questions on the unit round wait until you get a doctor alone, (when asked q's in front of other doctors they do have a tendancy to puff out there chests and act like they know everything, no-one knows that much! Remeber your team will know that you don't have the same experience, but will be aware that you have a different experience and skills to draw from, just be honest really, if you don't know something, admit it, it is a strength, not a weekness. As for codes - you will never be alone, the whole of icu works as a team. Good luck, mind you, it's December now, and i'm sure you're doing fine. - as for the stress of the job, it does exist obviousley, but becoming part of the team and de-briefing after events helps - as does the time honoured English tradition of after work nights out to blow off steam, and gel as a team in and out of work. Hope this helps!
