ROCHESTER — Twenty-two U.S. states, plus Guam and Washington, D.C., allow anesthesiologist assistants to work in operating rooms. That's a question state Sen. Liz Boldon, DFL-Rochester, is weighing — and something for which she's seeking more opinions. Anesthesiologist assistants are health professionals who have completed a premedical bachelor's degree program and an anesthesia-specific master's degree program. The current bill language would require that anesthesiologist assistants work under the supervision of an anesthesiologist, similar to how, in many states, physician assistants must practice under a doctor's purview. On Thursday, Aug. 6, in Rochester, Boldon and Sen. Lindsey Port, DFL-Burnsville, will hold a roundtable with anesthesiologists and CRNAs on the topic.
