Not much bothers me. However, when I was a nursing student and had the opportunity to sit in and watch an open heart surgery, I had quite the experience.
I had only gotten a few hours of sleep, I was VERY EXCITED to watch my first surgery! Not sure what happened, but after watching the anesthetist poking around the pts neck with a long needle, I got queazy. The feeling passed.
The surgery started, all the sudden, the queazy feeling returned, one of the nurses saw the look in my eyes, and pointed me in the direction to the bathroom. Fortunately, I made it to the bathroom by myself, but unfortunately, I didn't get my mask off in time, and threw up in my mask.
I felt so embarrassed. I cleaned up as quickly as I could so I would not miss much. Got back in to watch the rest of the surgery (6 hours). However, I didn't get the smell of vomit out of my beard, so I had the lovely smell of vomit in my new clean mask for the remainder of the surgery. I was too proud to leave again, plus I didn't want to miss anything.
Never had another experience like this, I think it was more nerves than anything
