forane...i thought the original poster had a very good legitimate question, but your post just rubbed me the wrong way...
1) we don't do the same job
a) MDs can supervise CRNAs and AAs and run 4 rooms at the same time
b) we provide ICU care, we run the PACU
c) we run all the research departments throughout the country
d) we can officially read an EKG
e) we do TEEs and interpret them
2) we don't have the same liability - which is reflected by our different malpractice insurance
rates - and in the court of law we are held to the standard of care of our peers (other MDs, not CRNAs)
3) "medical knowledge will only take you so far in anesthesia" - hmmm, that is a load of BS
4) anesthesia has cured people and it has treated diseases:
a) anesthesia for refractory asthma with isoflurane
b) phenobarb coma induction for refractory seizures
c) without anesthesia 99% of inpatient surgeries would be impossible
d) epidural steroid injections, spinal pump implantation, celiac plexus blocks, etc...
d) a large component of anesthesia is critical care and therefore involves the diagnosis and management of intra-operative:
1 - pulmonary/air/fat/cement/amniotic emboli
2 - myocardial infarctions
3 - and other intra-operative catastrophes
5) anesthesia training is not the same
a) CRNA gets 1500-1600 clinical OR hours during the course of study
b) MD gets 9500-10000 clinical OR hours during the course of study, which doesn't include 4-6 months of ICU time - and that doesn't include patient contact/medical knowledge acquired during medical school and internship. At the end of residency, I had done over: 15 pedi hearts, 90 adult hearts, 4 heart transplants, 6 BIVAD placements, 3 double lung transplants, 7 liver transplants, 35 neonatal cases (between the age of birth and 72 hours of life), 450 pedi cases, 80 thoracic cases (including 14 tracheal resections and reconstructions, and 8 carinal resections), 70 cranis (3 of which were done on cardio-pulmonary bypass), 4 ruptured thoraco-abdominal aneurysms, 29 AAA (of which 20 were supra-celiac) and over 2300 other cases.... 500 a-lines, 400 central lines, 250 PA lines (of course those numbers are a bit higher due to the high volume in the ICU).
6) you can't do everything I can do... How do i know this? because i assume that you are similar to the CRNAs I work with. They know that they can't do everything i can, and will come to me with pre-operative issues/questions, they will refuse to do certain cases due to complexity of care, and they will often ask me to come assist when they are having difficulty intra-operatively.
7) when you say that you can put your skills up against any MDA... what do you mean with that? can you put your knowledge up against any MDA too? (oh i forgot... according to you, medical knowledge will only take you so far...)
