There are many many many anesthesiologists with personality disorders who do not know how to communicate effectively, how to behave towards other humans in the best of circumstances. the specialty self selects those folks. Anyone wanna disagree? Throw in working with a CRNA(closely) who they deem inferior, thrown in a bit of stress and insecurity and they have an inner meltdown. This inner meltdown is manifest by demeaning crnas, rudeness, horrible body language. Imagine working with that daily!! It is no wonder they want to get rid of us. You have to make them do what you want them to do and make them think it was their idea. See how hard that is!
Residencies give poor training on how to properly supervise an anesthetic and how to have your wishes crystallized.
On top of that, you have many many lazy anesthesiologists who never answer pages, never come to the room, never offer to put in the iv, never offer to sit in the room during a long long case, . How would you like to work with someone like that? Would you want to get rid of that person?
You have to be engaged in all aspects of the patient care and never let the crnas think they are the ones doing the case and there is no back up which is what happens when one is never available
