During surgery using local anesthesia, the skills to infer and keep the patient's philological and mental condition under control are important to the surgeon. However, acquiring these skills is difficult in the training period as they are acquired only during actual surgery. From this viewpoint, we are developing a model which can represent a patient's philological and mental responses to surgical procedures. This model is expected to be used during training, where trainee doctors can experience the behavior of the patient and acquire the skills mentioned above. Measurements were taken during actual surgery. The heart rate, breathing rate and amplitude, and complaints of pain were recorded as the patient's response. The endoscopic view and scene in the operating room were recorded in order to determine the factors that cause each patient's response. To develop the model, the causal relationship between surgical procedures and patients' responses was investigated. It became clear that the patient's response is dependent on the surgical phase, movement of surgical area and the type of surgical tool. We constructed a model of this behavior using a Bayesian network.
