Postoperative Delirium Clinical Trial
Official title:
Modulation Of Frontal EEG Alpha Oscillations During Maintenance and Emergence Phases of General Anesthesia to Improve Early Neurocognitive Recovery in Older Patients
The investigators intend to recruit 600 participants to see if alpha power during anesthesia is influenced by analgesic medication and associated with a reduction of delirium following surgery.
Postoperative delirium may manifest in the immediate post-anesthesia care period. Such episodes appear to be predictive of further episodes of inpatient delirium and associated adverse outcomes. Intraoperative monitoring of frontal electroencephalogram (EEG) has been associated with postoperative delirium and poor outcomes. However, the efficacy of titrating anesthesia medication to proprietary index targets for preventing delirium remains contentious. The investigators aim to assess the efficacy of two pharmacologic strategies which could prevent post-anesthesia care unit (PACU) delirium (1) maximization of intraoperative alpha power during maintenance and (2) switching anesthesia regimes during the emergence phases of anesthesia. ;
