About this trial
Perioperative anesthesia can affect postoperative cognitive function. In our previous study, intraoperative dexmedetomidine (Dex) infusion reduced the incidence of delirium within the first 5 days after brain tumor. However, the mechanism is still unclear. With the development of neuroimaging, multimodal neuroimaging technology provide a new method to explore the underlying mechanism. Therefore, the purpose of this study is to analyze the alterations of brain network under sedation and anesthesia by different anesthetics in patients with supratentorial glioma and their association with cognition.
