Injections are actually kinda gratifying. If you do it correctly, 9 out of 10 pt's won't feel it.
I work in surgery, and have scrubbed in on cases where I use both hands to move bowels outs of the Dr's way. I have held a beating heart, I have helped yank a uterus out, I have pulled necrotic tissue off a belly, I have held a tumorous breast mass in my hands, I have manuvered joints in unnatural positions, I have done the most unreal and some would say discusting things imaginable. Just today I assisted on a BKA. The hardest past is being the circulator and taking the leg off the field.
Yet nothing makes me gag like being on the floors and cleaning what we in the OR call a "code brown." I had children. Their nasty diapers never made me blink or bat an eye. But you take a 150-200 pound adult, and give them a healthy dose of golightly and I'm trying REALLY hard not to let them hear or see me gag. This is one of the reasons I HATE clinicals! No offense to the med-surg nurses out there, but my GOD how and WHY do ya'll do it?? There are so many specialties these medical detectives (that's what med-surg RN's ARE) could excel in. The only thing attractive about being a med-surg nurse is that you can REALLY gain an understanding of pathology, and that you get to have real patient interaction. We miss most of that in the OR, and I suspect many other specialties miss it as well.
Nevertheless, Blood and guts and sawing bone is no match for **** and sputum in the gag dept. Blood's purty and guts are no grosser than skinning a chicken. Even the smell of a bovie searing flesh is less gag inducing than an impacted 79 year old. Unless, of course, the flesh is gangrenous. Then, we all fight over the spearmint.:chuckle
Bottom line, if you look at the body scientifically, and take it from there, you really shouldn't be grossed out. It's a wonderous sight to behold.
