Who does the scrubbing @ your place?

I am curious.... I am an IV certified LPN who works @ a hospital in an Endo unit. Our facility uses LPN's for scrubbing with the doctors.... We also do Bronchs and Paracentesis that we assist with. From reading the forum I have gathered alot of places don't use LPN's.... I am just curious about other facilities. We are also able to Pre-op & Post-op the patients because there is an RN available @ the desk. The RN also verifies all our pre-op hx assessments etc...... I have wanted to go back to school to get my RN for some time now, but I love what I do and don't want to give up my job!
