[Normovolemic hemodilution during surgical revascularization of the myocardium]

The hemodynamic efficiency of hydroxyethyl tarch 130/0.4 "Voluven" (HET) was investigated within a method of acute normovolemic hemodilution in 11 patients with ischemic heart disease (IHD) during the implementation of surgical revascularization of the myocardium under the conditions of extracorporeal artificial blood circulation. It was shown, that in case of invasive monitoring of central hemodynamic and of the oxygen-transport function of the blood circulation system, an exfusion of 13.28 +/- 1.53 ml/kg can be regarded as a permissible blood-saving procedure in IHD patients during revascularization of the myocardium. The application of HET 130/0.4 "Voluven" provides for an adequate correction of shifts in the blood circulation system and in its oxygen function--such shifts occur in implementing the acute normovolemic hemodilution in IHD patients.
