Precedex, hit or miss as maintaining sedation, innappropriate for intubation related sedation induction. We use the following depending on the pt, situation, etc... Versed + Fentanyl as gen maintainance and induction. Sometimes we will use paralytics, Etomidate for example for the intubation. Prop on occasion for those that dont tolerate weaning off versed for breathing trials, extubation. The MDs you speak of are a$$h@t$. This is the type of stuff that a 1st year fellow would try, not an attending worth their salt.
