[The central hemodynamic indices of patients with ulcerative gastroduodenal hemorrhage]

Changes in certain indices for central hemodynamics in the early period after emergency operation were evaluated in 79 patients with helcoid gastroduodenal hemorrhage, the patients' age ranging between 18 to 80 years. At admission all patients demonstrated lowered cardiac and stroke output, cardiac and stroke indices, with the total peripheral vascular resistance being slightly increased. Operation aggravates disturbances in hemodynamics caused by loss of blood. Under the effect of corrective therapy, from day 3 to 5, indices for central hemodynamics tend to slowly return to normal as do those for hepatic bloodflow. The impairment of the function of the circulatory system appear to be greater in cases presenting with deficiency of globular volume of excess of 50%, whose compensatory potential is under too severe a strain. At discharge from the hospital, the percentage of those cases presenting with hypodynamic type circulation amounted to 67.3%, normodynamic having been 32.7%.
