[Effects of a defined infusion of 10% HAES 200/0.5 in the early phase of a septic syndrome on hemodynamic parameters].
In an animal model the hemodynamic effects of three infusions of HES during the early stage of a septic syndrome were examined. In nine pigs with a body weight between 29 and 36 kg a septic syndrome was produced by infusion of E. coli endotoxin. 1, 4 and 7 hours after beginning of the endotoxin infusion 250 ml HES 200/0.5 were infused. After the 1st and 3rd infusion an increase of the cardiac output resulted, which was previously lowered, without changes of the CVP. During normal CO the 2nd infusion shows an increase of CVP and MAP. PWP did not change. The reactions of the hemodynamic parameters can be well explained physiologically. A volume supply at a reduced CO increases the latter without influence of the CVP. Normalized CO before the infusion resulted in a CVP-increase. The PWP is not evaluable under the conditions of an elevated pulmonary resistance, as it exists at the septic syndrome.
