Type C: Falling and then rising of blood pressure in the course of operation. Type D: Falling of blood prassure after the operation. Type E: Falling of blood pressure soon after rising in the course of operation.
2. Major fluctuation of blood pressure is not found in the course of operation (extracting teeth), when 10cc of 1 per cent hydrochloric procain was injected for the purpose of anesthesia, with or without a drop of 0.1 per cent of adrenaline.
3. As to the patients (to extract teeth), when observed by psychogalvanic phenomenon, spiritual excitement is closely connected with the fluctuation of blood pressure.
4. As to the indoor patients, no sudden falling of blood pressure is not observed soon after the commencement of operation.
