Outline of Final Research Achievements

Minimally invasive surgery is a burden for surgeon because of peculiar endoscopic skills and many kinds of new surgical devices while it is less invasive for the patients. Intraoperative stress and fatigue of surgeons potentially affects operative quality and compromise patient safety. Assessing stress and fatigue during the surgery is important for the quality and safety of the operation, while we have little knowledge about quantification and estimation of the stress. In this study, we analyze physiological data (heart rate, perspiring volume), voice (frequency analysis etc.) and velocity of hand movements of the surgeon to evaluate the usefulness as the predictor of the stress and fatigue during the operations. It revealed that the voice analysis was useful to evaluate the stress and fatigue among them.
