I worked in a Level 2 OR. Where I was, I only had 9 weeks of orientation and I had never worked in the OR before! I was a float, too, and moved between ortho, general, neuro, vascular, gyn, and even robot. There is a VERY steep learning curve and I wish I would have had more orientation time up front. I worked there almost 1 year then left for a different job, partly because I never really felt comfortable. Luckily, I worked with some really great nurses and scrub techs who helped me out, but a few found pleasure in making the new people look bad. I actually outlasted the new person before me and one behind me, too, due to inadequate training. I am proud to say I was never kicked out of a room, but it was hard at times not knowing what they were asking for and having to find it.
My absolute least favorite was ortho - mainly because of the prep. We had to prep the surgical site where I was, but I heard some teaching facilities have the residents do it. Second least favorite was brain related neuro stuff...spinal was fine.
Overall, it was a GREAT experience and nice environment. We had fun between cases and setting up for the next one. Some of the surgeons could be very difficult to deal with, but many were very nice. I would have potentially stayed if I had more orientation time to learn the different supplies and instruments, but it just wasn't where I was meant to stay.
