We examined the change in circulatory kinetics due to an increase in intraabdominal pressure by adding pressure quantitatively to the abdominal wall by rneans of the manchette technigue by using mongrel dogs, and obtained the following results:
1) By adding to the pressure to the abdominal wall, the pressure of inferior vena cava at the confluence of right and left common iliac veins showed a significantly higher value (p＜0.05) than those at other 4 areas of the vena cava from just above the diaphragm to the above confluence.
2) All the dogs in the group with 20mmHg pressure survived for 24 hours, while those in the group with 40mmHg pressure died in all after survival between 13.8±2.05 hours.
3) The pressures of the inferior vena cava at the confluence of right and left common iliac veins with 20and 40mmHg showed no significant difference immediately after the pressurization, but thereafter showed a increasing tendency in the group with 40mmHg (p＜0.05). This increase in the pressure of the inferior vena cava lead to peripheral circulatory insufficiency.
4) The measurement of the pressure of the inferior vena cava at the confluence of right and left iliac veins in case of increased intraabdominal pressure seems to be an effective index for the risk of intraabdominal pressure.
