Cerebral oximetry is a valuable noninvasive monitoring tool for assessing brain oxygenation and overall organ perfusion in cardiac surgical patients.
May support cerebral oximetry for risk stratification and perfusion monitoring; leaves open outcome benefits pending prospective trials.
Cerebral oximetry based on near-infrared spectroscopy (NIRS) is increasingly used during the perioperative period of cardiovascular operations. It is a noninvasive technology that can monitor the regional oxygen saturation of the frontal cortex. Current literature indicates that it can stratify patients preoperatively according their risk. Intraoperatively, it provides continuous information about brain oxygenation and allows the use of brain as sentinel organ indexing overall organ perfusion and injury. This review focuses on the clinical validity and applicability of this monitor for cardiac surgical patients.
