[Computer monitoring of hemodynamics during assisted circulation and extracorporeal detoxication in abdominal surgery].

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.
