Too much critical care experience?

This is a question for SRNAs and new grad CRNAs but those of you with more experience, please feel free to enlighten us as well.

I have heard in several places that anesthesia is much different than ICU nursing. Beyond the requisite year or two of critical care experience, does anyone think that too many years in the ICU would hamper your thinking as you transition over to being an anesthesia provider rather than a nurse.

If this is the case, what are the differences?

Thanks.
