Endo tech duties

I'm wondering about what the Endo techs in everyone elses hospital based GI labs do with regards to injecting epi, Botox and other meds through the scope and whether or not your techs assist in bronchoscopy with handing lido and epi to the pulmonologists. There has been some recent questions regarding scope of practice with this. There is always an MD in the room and always an RN.
