EEG Characteristics of Different Sedation Depths in Neurosurgery Patients

Gliomas are the most common primary intracranial malignancy, and behavioral experiments in patients with supratentorial gliomas under sedation have shown potential neurological abnormalities; however, these behavioral experiments are susceptible to external influences. Therefore, more objective evidence is needed to support and extend the existing conclusions. The purpose of this study is to compare the EEG signatures (such as the EEG signal power) at various levels of anesthetics induced sedation in patients with supratentorial glioma in frontal lobe and in patients without intracranial-occupying lesion.
