Talk to just about any residency program in your area about an "Advanced Clinical Anesthesia Fellowship" in general anesthesia. You should have no problem finding a program that will sign you up for a year. You will likely make less than 1/4 of what you would make if you were out in practice, but some places will let you make more. You should be able to easily get 60% supervised work with 40% independent work as an attending. They may even be willing to negotiate so that you progress into independent responsibility. Start out 100% supervised and progress throughout the year until you are working 100% independent (meaning you are supervising residents and/ or CRNAs most likely).
University of Washington would go for this. I know UMASS used to have a program like this, but the website doesn't list it anymore. You can try Googling Advanced Clinical Anesthesia Fellowship, but most of these listed are for a specific area like ENT, ortho etc as opposed to a general, wide-ranging fellowship.
Good luck.
