Pausing propofol during neurosurgery to record intraoperative electrocorticography is feasible;10 years of clinical experience.

Objective: Intraoperative electrocorticography (ioECoG) during neurosurgery is influenced by anesthetics. In our center we stop the propofol to enable interpretation of ioECoG. We reported our clinical experience and evaluated awareness and hemodynamic changes during the propofol-free periods (PFP).
