Blood Pressure Changes Correlated with Time, Length and Type of Intestinal Strangulation in Dogs.

Abstract

There appears to be a direct correlation between the iall in blood pressure and the time, length, and type of vascullar occlusions. In general, the longer the time and the longer the loop, the greater the fall in blood pressure. The type of obstruction, however, is of even greater importance than the time and length of the occlusion. In those instances in which the veins were ligated and in the encirclement strangulations (Group I), in which the arteries were not entirely occluded, the fall1 in pressure was much more rapid than in those instances (Group III), in which the arteries were absolutely occluded regardless of the condition of the veins.
