While it is true that SOME surgeons yell, and SOME staff cry, it isn't an everyday occurrence. The days of surgeons yelling just because they feel like it are by and large gone due to policies such as 'disruptive behavior' and heavy fines/restricted surgical time levied on surgeons as a result of violating these policies.
The key to combat this is to call them on it. I will never forget the day when I was fairly new to the OR and the surgeon asked for something under his breath. The scrub tech heard him, but didn't repeat it for me. I asked, "What was that you need?" The surgeon puts down his instruments, looks at me like I am the village idiot and yells, "I SAID that I wanted a Deaver retractor! I use it for every procedure! Do you know what that is or do I need to draw you a picture?" The tech snickered. I calmly, but in a direct manner stated, "I don't have a comprehension problem. You tend to mumble when you are focused, and our tech should have repeated what you said since I was clear across the room changing out the suction so you wouldn't yell at me when the suction stopped. Moreover, if you use a Deaver for every procedure, I am at a loss as to why our tech seemed to forget this key instrument. I will make note of this on your preference card and give it to the Nurse Manager to amend so that you won't run into this problem again." That surgeon never yelled at me again, and when he got to know me, he actually requested me in his room.
I don't want you to be of the mindset that the OR is a war zone. It isn't. You will see things and experience things in the OR that are truly awesome. For example, assisting a surgeon during an emergency ex-lap and seeing the black/red loop of necrotic bowel (it sure is stinky), doing internal cardiac massage when a pt codes on the table during an open heart procedure, seeing for yourself what sort of damage the lungs suffer from smoking (looks like pebble sized black marks all over the lungs), seeing and feeling how hard the liver can get from cirrhosis, actually seeing the carotid artery during en endocardectomy, and seeing what cancer looks like in the mesentery, on the liver, in the bowel...it is amazing.
If you are working in a university hospital, you will see all kinds of transplants-heart, lung, kidney, pancreas, and liver. You will also be involved with organ harvests for donation.
There is an entire world to be exposed to in the OR. At this juncture, you must think about what YOU want the most. What really grabs your attention? Do you want to be more hands-on and interact with patients? Do you want to learn time management skills first? Do you want to learn medication administration/blood administration/chemo administration? I think that the floor would be a great place to start if you want to get the basics down first and then proceed to the OR if you still have the desire. I started out on the floor because it was my choice, and then realized that my favorite patients were post ops. That's when I started thinking that PACU would be better suited for me. After several years in the PACU, I was intrigued by the OR. When I got to the OR, I never looked back.
