Role of Cerebral Oximetry in Reducing Postoperative Morbidity Following Cardiac Surgery

"Predefined protocol of interventions for correcting rSO2 desaturation (\< 60%) during cardiac surgery and the first six hours after it.~In case of rSO2 decrease less than 60% correct:~head position; position of aortic,venous cannulae and central venous catheters; partial pressure of carbon dioxide in arterial blood \< 35 mmHg; mean arterial pressure \< 60 mmHg; central venous pressure \> 10 mmHg; cardiac index \< 2.0 l/min/m2; mixed venous oxygen saturation \< 60%; hemoglobin \< 65 g/L during cardiopulmonary bypass or hemoglobin \< 90 g/L after cardiopulmonary bypass; decrease cerebral O2 consumption."
