ObjectiveSome critical events in anesthesiology occur as seemingly preventable misadventures, their exact origins indeterminable. Inexperienced anesthetists, anesthesia machine malfunctions, lack of vigilance and human error inevitably initiate some incidents. Anesthesia training improves recognition and decision-making. Avoiding crisis initiation and amelioration of those that do occur is one role of the consultant anesthesiologist. Safe patient care requires medical and procedural knowledge, technical expertise, and control of resources in a complex milieu. Anesthesia simulators are clinical laboratories where anesthetists can sharpen both cognitive and manual skills. Dynamic scenarios allow opportunities for anesthetists to explore and experience crises as they develop and apply their knowledge while attempting to manage these events. Simulator-based scenarios are reproducible and large amounts of useful data can be collected and saved. The authors hypothesize these data can be utilized to compare performance of anesthetists and to measure improvement of individual anesthetists over time.MethodsWe have designed "Stable Anesthesia," a prototypic scenario to test anesthetists' capabilities under the stress of performance guidelines. Three subjects performed anesthesia using the simulator and this protocol. Data from the simulator were archived by the system and analyzed by the authors.ResultsA simple mathematical analysis gave good separation of data from three subjects of different training level.ConclusionsIt is suggested that the use of the techniques mentioned here may be of value in the development of a standardized testing protocol for anesthetists.
