Abstract
Cerebral oximetry is a non-invasive technology utilizing near-infrared spectroscopy to permit cerebral oxygenation monitoring in a portion of the frontal cortex. With the aid of cerebral oximetry, research has demonstrated that cerebral oxygen desaturations are a frequent occurrence during thoracic surgery after initiation of one lung ventilation (OLV). In adult patients greater than or equal to 18 years of age undergoing one lung ventilation, does use of cerebral oximetry provide a reliable indication of early postoperative cognitive dysfunction compared to one lung ventilation without use of cerebral oximetry? Cerebral oximetry levels should be maintained at or approximate to 20% of the baseline level obtained before initiation of OLV. Incidences of delirium are possible after thoracic surgery utilizing OLV; however, intraoperative cerebral oxygen desaturations have not been consistently associated with postoperative delirium. Nonetheless, utilizing intraoperative goal directed therapy with cerebral oximetry has demonstrated decreased incidences of postoperative delirium in the elderly population after OLV. Evidence is present to support the usefulness of cerebral oximetry as a predictor of postoperative cognitive dysfunction in elderly patients undergoing OLV; however, the device has not been universally accepted as a reliable indicator of neurocognitive decline in thoracic surgery. Based on the evaluation of current research, use of cerebral oximetry during OLV can allow providers to trend cerebral oxygenation saturations from baseline and appraise any level of decrease that might prompt intervention. Evidence suggests that the elderly population are vulnerable to emergence delirium which can further be accelerated by hypoxia. Because thoracic surgery utilizing OLV is known to cause cerebral desaturations, it would be prudent of anesthesia providers to incorporate cerebral oximetry monitoring in this vulnerable population.
