[Hemodynamic parameters and saturation of the cerebral cortex blood with oxygen during extracorporeal circulation in heart surgery].
Sixty-three patients were intraoperatively examined during heart surgery with extracorporeal circulation (AEC). They were operated on for an affected heart-valve apparatus (AHVA) and ischemic heart disease (IHD). There was a perioperative monitoring of central hemodynamics, pressure in the bulb of superior jugular vein (BSJV) and electroencephalography (EEG). Regional oxygenation of the brain was made in real time by a INVOS3100 oximeter (SOMANETICS, USA). A maximal saturation of the cortex blood with oxygen at AEC was registered in patients with AHVA at an average pressure below 70 mm Hg, and in patients with IHD--at 85 mm Hg. An increased pressure in BSJV at a constant mean arterial pressure and at AEC is related with blood outflow from the venous collector of the brain.
