I am critical care, through and through. My favorite sight is an IV forest. The very best part of ICU is that it is so darn cerebral. ER has the heat but somebody is always thinking for you.
I have been doing this for 13 years. My oldest daughter does surgical heart ICU. My oldest son is a traveler, out in Denver at the moment and ICU as well. We all agree. The more bells and whistles the better.
I remember when I was in nursing school. Rotation after rotation there was no fit. I was depressed and remember getting a hug from one of the instructors while crying on her shoulder about it (something I NEVER do). She said, "When you get there, you'll know... trust me". The following semester put me in ICU for two weeks. The double doors opened with a punch, the rush of air hit my face and I strolled in. There in front of me were 8 on the brassiest babes I had ever met... not one, eight. I was in hog heaven. I love the attitude, the guts, the intellect and compassion of ICU nurses. I love watching the 'windows' appear, sorting through my bag of tricks, knowing what needs to be done and turning something bad into little miracles.
Though I respect floor nursing, I could never go there. I need close, intense contact with the patients I care for. I, too, loved my psych rotation, but after sitting in with the docs at the end of the day and listening to them belittle the patients and joke at their expense, I knew I could never be a part of the hypocrisy.
As a crusty old ICU RN I repeat to you the advice that was passed on to me... "When you get there, you'll know... trust me".
