A Plague on Both Your Monitors! Are Bispectral Index and Cerebral Oximetry Useful for Reducing Postoperative Cognitive Impairment?

Perioperative neurocognitive disorders, such as postoperative delirium and neurocognitive disorder postoperative (also known as postoperative cognitive dysfunction), plague many older patients after cardiac surgery.1 The pathophysiology of these conditions remains poorly understood,2 which likely explains in part why there is currently a lack of effective preventative techniques or therapeutic modalities for these disorders. Both processed electroencephalogram (EEG) monitoring to titrate anesthetic dosage and regional cerebral oxygen saturation (rScO2) monitoring to improve cerebral oxygen delivery have been proposed as methods to reduce perioperative neurocognitive disorders, with mixed results.
