[Statistical analysis of anesthesiologists' thinking patterns concerning regulation of the blood pressure and the concentration of inhaled anesthetics].

During surgery, the anesthesiologists adjust the concentration of inhaled anesthetics according to the change in blood pressure in order to achieve good control of anesthesia. Usually the thinking patterns of individual anesthesiologists differ from one to another. We obtained data from each anesthesiologist's thinking pattern concerning the regulation of blood pressure and the concentration of inhalational anesthesia. These patterns were analyzed statistically and compared for individual anesthesiologist. The results showed that anesthesiologists' regulation rules were formed independently of the 3 drugs and were specific to individuals. Some trends depending on institution were observed, but no statistically significant difference was found.
