Cerebral blood flow velocity (as an index of regional perfusion), dynamic cerebral autoregulation and regional cerebral oxygen saturation should be monitored if disturbances of cerebral perfusion and oxygenation have to be suspected. Noninvasive monitoring techniques are established. When detected early, disturbed perfusion and oxygenation may be treated promptly and permanent damage of brain tissue can be avoided.
In critically ill patients, hemodynamic changes occur due to the disease itself but also as a function of diagnostic and therapeutic procedures. Systemic hemodynamic changes can be monitored using PiCCO® system (pulse contour cardiac output, Pulsion Medical Systems, Munich, Germany) that combines transpulmonal thermodilution and pulse contour analysis. PiCCO® continuously monitors cardiac output (CO), as well as static parameters like global enddiastolic blood volume index (GEDVI), and dynamic parameters as difference in pulse pressure (dPP) and stroke volume variation (SVV), respectively. CC Nexfin® (BMeye, Amsterdam, The Netherlands) is a noninvasive hemodynamic monitor.
This study investigates the effects of changes in cardiac output on cerebral blood flow velocity and regional cerebral oxygen saturation in intensive care patients that underwent major abdominal surgery.
