An anesthesiologist assistant (AA) is a non-physician anesthesia provider qualified by advanced education and clinical training to work cooperatively with an anesthesiologist in developing and implementing the anesthesia care plan.
Physical stamina and manual dexterity are necessary for the practice of anesthesiology. The anesthesiologist may work a 60-hour week, and the working hours can be irregular with the need to be on call for emergencies.
