Abstract
Abdominal distention in dogs produced variable changes in the carotid blood pressure, a rise in the pressure of the veins of the hind legs and slight, inconstant changes in the pressure within the superior vena cava. Sudden release of abdominal tension restored the pressure in the veins of the hind legs approximately to normal. It also caused a fall in the carotid blood pressure accompanied by a decrease in the stroke volume of the heart. The duration of the distention of the abdomen did not modify the effect of release of tension. The syncope and deaths sometimes encountered in patients following the release of abdominal distention, on the basis of these exps., can be ascribed to the decrease in peripheral resistance resulting from the removal of compression of the abdominal aorta. On this basis the emergency use of adrenaline is suggested.
