Good advice above.
A good relationship with the circulating and scrub nurses/techs is important. Their worst fear is someone who doesn't know what they're doing coming in and contaminating areas that take a LONG time to set up. Be very aware of what is sterile and what isn't. If you're scrubbed in and inadvertently reach down below your waist or scratch your cheek, immediately ask for a new glove, etc. If you're not doing anything, just stand where you are not in anyone's way but can see well what's going on and keep your hands folded in front of you like you're praying. This will keep you from all evil. 🙂
Enjoy your rotation! I was amazed how much I loved my surgery rotation. Hope you are, too.
