I work at a rural, 3 OR hospital. So, many times, we must watch who is in the room, as they could be close friends or family members, which are not allowed.
We have at times, lots of students, paramedics, RN students, scrub tech students, student physical therapists, x-ray students and even sales rep students.
Students are worked through our education dept, the schools involved go through a process with them, then both are in contact with our supervisior, a schedule is set up, etc. We keep the number of people down in the room. One to one is ideal, and we try to stay on that ratio.
Before any student or rep goes into the room, they have to read and sign a form that says essentially, that they understand basic sterile technique and OR operations, they take responisibility for their own actions, and that they can be asked to leave or not admitted to the room at any time at the descresion of the operating personnel.
When I have a student with me, I normally introduce them to the pt in holding area, and if that pt has issues, the student won't go in. I rarely have had any problems, most pt's know they have to learn and we are not "practicing" on them.
Students are also told to initially lean on a wall, and eventually, we will get them into a good position to see. I try to put them in an area that they can see everything, and ask them to watch, and see what we are doing, and why, and if they have a question....ask.
I like students to give and take when possible. Makes them think, and us too.
They also are told that if the "manure hit the air conditioning",,,again, put your back up against a wall, and watch!
I rarely feel the students are an intruder, we've had a few that felt they needed to impress us with what they knew, which I dislike. Yes, they may have more knowledge than me in some things, but that's not what they are here for today. They are basicly here to watch, and learn from us.
Hope that helps.
