i work in the OR and its always cold, but u get use to it very fast.
i would add, dont bring anything in ur pockets like ur keys, valuables, wallet, money, etc, always keep that locked up in your locker because u dont want to lose it and u dont want to have any metal or anything on you. Also, dont bring your school bag or what not into the OR area unless you are allowed too. this is a sterile temperature controlled and atmosphere controlled area. I will see doctors bringing soda and food into the area, but not into the room. This doesn't mean you can bring your bottle of water or what not with you tho.
If they do let you get dressed in a gown or what not and your in the room and for some reason you are near the sterile environment, you always pass a person back to back because the back of a person is where the germs would be and the front is the sterile area in most cases. for instance, if your sterile and the doctors sterile, you dont walk right by infront of him because your letting your germs brush away onto him or onto his hands. Also always keep your hands up if they let you put gloves on, dont cross them on your chest unless u got a sterile gown on, or dont let them hang down or be below your belt. Im sure you see this on tv all the time where you see them walking around with their hands up like there nuts. same things applys.
when you are wearing eye protection, make sure u get a mask that keeps the steam out of your eye protection glasses because many times people put on a regular mask and when they put their glasses on, they steam up from their breath. there are specific masks that prevent this from happening, and they are usually lined with a plastic on the inside to keep the moisture in.
oh and if it starts to smell for whatever reason, like bile or just some uncontrollably disgusting smell, it will happen lol, the nurses might have some mint stuff to get rid of the smell. i am not quite sure the name of it, but its a mint bottle that u put on your finger and then swipe on your mask and keeps the smell from intoxicating you. if u cant stand the smell, ask if the nurse has some mint for your mask, they usually will kno what u mean.
also when u have perfume and what not, do not spray it all over your scrubs or what not, its nice to smell good, but u dont need to overkill us and especially the patients. many patients are sensitive to things and the last thing we want is your patient breaking out or being anaphylactic because u got some weird perfume or cologne on. you can wear deoderant tho. some cases will ask that u not, but usually it will specify if their an abbi patient.
other than that, have fun.
