RESUMEN
The researchers of the Department of Medical and Biological Cybernetics and Hospital Surgery Department No. 2 of the Russian State Medical University have developed the first stage of an automatic diagnostic system to evaluate gastroduodenal motor function by intracavitary multichannel manometry. The system makes diagnostic syndromal conclusions by using an expert approach and statistic data analysis. The percentage of correct diagnoses was 92 and 80%, respectively. The system may be useful at multidisciplinary hospitals, diagnostic centers, and specialized gastroenterological care facilities.

Basic central and regional hemodynamic parameters have been studied using a computer monitoring system in 57 patients with acute abdominal surgical diseases during special extracorporeal procedures. Indications for regional assisted circulation (RAC) as well as regularities in hemodynamic changes during and after procedures have been established. The data of monitoring have shown that RAC and RAC in combination with hemosorption have in most cases a marked favourable effect on abdominal hemodynamics: mesenteric and portal blood flow is increased and consequently total hepatic flow is activated. The flow of portal blood leads to an increase in central venous pressure. Unfavourable tendencies have been established in changes of central hemodynamics during the procedures. They are: calculated intervals of the rates of central venous pressure increment and cardiac output decrement. This made it possible to optimize the use of extracorporeal procedures in patients with such diseases.

Changes in basic central and regional hemodynamic parameters have been studied in 46 patients with diffuse peritonitis using an automated system of constant intensive circulation monitoring. It has been established that the type of circulation did not reflect the severity of the condition in patients with peritonitis, but a characteristic combination of central hemodynamic parameters makes it possible to assess compensatory reserves within each circulation type, as well as to identify unfavourable hemodynamic tendencies. Analysis of changes in the circulation parameters in the course of peritonitis development is necessary to predict the course of the disease and its outcome. There was a considerable difference in circulation parameters patterns of patients who recovered and died of the disease. The principal differences manifested on day 2 postoperatively. Abdominal hemodynamic changes are specific and characterize the severity of peritonitis beginning from the first day of observation.
