I apologize if it comes off as condescending.
The first week of our doctoral training we were constantly reprimanded for making broad statements, like denigrating an entire profession, without hard evidence or statistics. I was constantly reminded in my weekly research papers or even in lecture that anecdotes and opinions carry as much weight as the air it's spoken on. After three years it has become second nature for me to disregard discussion that has no research, evidence, or merit beyond a single persons perspective. It may be interesting as far as stimulating you to investigate if this perspective is shared with more than one person, but even on here a sample size of 50-100 people would not be statistically significant.
I know this is the internet and I could be speaking to a 19 year old at a junior college but let's strive to be better. If we have strong opinions like "CRNAs have a fraction of training, CRNAs will kill patients if a physician isn't directing them, CRNAs are only good for basic healthy cases, MS3's can perform anesthesia safely" you need to support this with peer reviewed research and statistics. Otherwise, it's as relevant as me saying the sky is green.
As someone who has completed three years of anesthesia training and am graduating, I've been in the research, I've provided anesthesia for hundreds of cases, thousands of clinical hours, many complex case types and procedures, and I already have an opinion on CRNAs practice, capability and safety. You won't see me making those definitive opinions here though, unless I supply the research and statistics behind it.
