I agree. I have gone ‘down under’ a couple of times, and it worked out okay. This was always at a Veterans Hospital.
Once a good anesthesiologist knows your vitals, your body type, your temperment (hypochondria?) and general health, they can decide what works best to keep you out but still safely breathing.
