ST,
You've been given the correct advice: khakis and shirt/tie. No need to ask doc. As for helping, sure, that's a touchy one though. Grabbing a patient's feet after a surgery, even if sliding over, should be handled by a tech/transporter. Be there, but don't be in the way. Be ready. If a nurse or doc asks you to help, help. Don't move in on a patient post-op though as if it's your right to assist, it's not. I've done it, others have, but there's a protocol here. Wait to be asked the first time unless your arms are direly needed.
Have fun with it. Don't stress. Be early, have fun.
HERES AN IMPORTANT TIP! The OR environment creates some stress whether or not you are observing, operating, providing anesthesia. EAT BEFORE YOU GO IN THERE. Every morning. Last thing you want is to get light headed and pass out. You'll have a cap on, a mask, and if you're not used to this, you could get jittery and lightheaded. You wouldn't be the first one. I've seen it. Make sure you eat in the AM. Best advice I can give you!
