As an aside, I know they are offered in the US, but I'm not sure why anyone would do a fellowship in neuroanesthesia, or trauma, or some of the other questionable ones unless you were going into academic medicine with the intent to build a career in that subspecialty AND were using the fellowship to land your dream job AND jump start your research career. I hope these clinical fellowships are not being done by many people. They don't really teach you new skills that you can't learn on your own on the job.
