Whats the difference between being a nurse anesthetist and a doctor anesthetist?

Training: From my experience working with nurse anesthetists, difference is training, which is much longer with anesthesiologists who are physicians. They are trained to deal with any kind of complications that can happen during and after an anesthetic. While most nurse anesthetists have harder time to deal and treat these complications. I f an anesthetic is uncomplicated either one can do a good job.
