AbstractIn 40 patients, whose expected hemodynamic instability during surgery necessitated invasive monitoring (Swan-Ganz catheter) and arterial pressure monitoring the hemodynamic and oxygen transport parameters in conditions of hypervolemic hemodilution were investigated in randomized tests. After insertion of an arterial catheter (arteria radialis) as well as Swan-Ganz pulmonary arterial catheter via the vena jugularis interna, one of the two volume substitutes selected at random was infused in quantities of 125 ml/5 min and the hemodynamic changes were measured after infusion of 500 ml and finally after a wedge pressure of 18 mmHg was reached. Using either solution, the measurements indicated significant increases in mean arterial pressure as well as in central venous pressure (ZVD) and wedge pressure. The cardiac index, left ventricular stroke work index, and stroke output rose consecutively and pulmonary vascular resistance went down in both test groups. In the case of both volume substitutes, there was an improvement in oxygen availability. The hemoglobin content decreased in both groups, though to different degrees in each group. Although the hydroxyethyl starch group registered a greater improvement in the cardiac index, a bigger decrease in pulmonary vascular resistance, a higher rise in the left ventricular stroke work index and a more significant improvement in stroke output, smaller quantities of the volume substitute were required in this group than in the group in which volume substitution was carried out with human albumin 5%.(ABSTRACT TRUNCATED AT 250 WORDS)
