Abstract

Abstract CIRCULATORY collapse following acute myocardial infarction usually is attributed to a central or "pump" failure. Contrariwise, circulatory failure following blood loss is associated with peripheral hemodynamic alterations which, although not fully understood, may lead to circulatory collapse in spite of restoration of blood volume. Moreover, the relative roles of central pump failure and peripheral vascular failure in the genesis of surgical shock are ill-defined. Further, the hemodynamic patterns and interrelationships between shock arising from different etiologic agents as hemorrhage, trauma, and sepsis are poorly understood. The present communication describes hemodynamic measurements in a series of 100 patients who were in various degrees of circulatory disturbances. Included in this series were normal control subjects; patients who had been in shock but were compensated at the time of study; patients who were in shock incident to hemorrhage, surgical trauma, and sepsis; and a group of patients with miscellaneous surgical problems.
