1. I am fine with techs assisting the doctor! As long as you've been trained properly. It doesn't take an RN to do biopsies, etc. Where I work, the RN's are required to do the tattoing, injecting epi and so on, though.
2. We actually don't spray the patient's throats (or have them swish lido) where I work. This is because we have anesthesia sedation which is deep enough that they seldom gag or have problems. We also found that the spray more often than not just caused a lot of coughing from vocal irritation. I guess I would have to say it should be an RN job to do the spray, though. Not that it's that difficult, but it IS a medication so........
3. As for the pay scale, couldn't tell you! I have no clue what our techs make???? If I had to hazard a guess I'd say maybe around $10/hr???? I'm just guessing, though!!
Good luck! Welcome to GI. I've been doing it for almost 4 yrs. I really love it.
