I remember feeling a bit queasy in my OR rotation, when they had people open from stem to stern, and were using retractors & cautery, etc. All that standing still & the lack of airflow...it was really a white knuckle experience! It took all I had just to take some slow deep breaths. LOL! I found it interesting, but at times I felt like it was so hard to watch.
Yet, it turns out I function pretty well on the nursing floors...and I've seen some very nasty and serious wounds. I have seen deep abdominal wounds the size of footballs, gangrene, purulent drainage and the like. Not that I am "used to it," but you do get a little desensitized after awhile. We are all human, and each has his or her own "limits." I have heard of surgeons keeling over in OR because they didn't eat breakfast and/or just didn't feel up to it that day.
Hang in there, it will get easier. My coworkers & I can talk about yucky wound stuff while at lunch...and it doesn't bother us at all.
