    Effect of remifentanil on three effect-site concentrations of propofol and their relationship during electroencephalography at loss of response, at maximum alpha power, and at onset of burst suppression: a prospective randomized trial

    For maintenance of anesthesia, plasma concentrations (Cp) or effect-site concentrations (Ce) of propofol widely vary among patients [ 1 ]. TCI (target-controlled infusion) systems and electroencephalographic (EEG) monitoring enable us to adjust and …

    Pathological and Physiological High-frequency Oscillations on Electroencephalography in Patients with Epilepsy

    High-frequency oscillations (HFOs) encompass ripples (80 Hz–200 Hz) and fast ripples (200 Hz–600 Hz), serving as a promising biomarker for localizing the epileptogenic zone in epilepsy. Spontaneous fast ripples are always pathological, while …
