Our patient is a 47-year-old male with a history of developmental delay and chronic ventriculomegaly was successfully extubated after external ventricular drain weaning. While his mentation improved, he had ongoing difficulties clearing secretions requiring a heated high-flow nasal cannula and repeated nebulizer treatments. The following day, the patient acutely had a seizure, manifesting as obtundation, whole body rigidity, and left lateral forced gaze deviation. Given ongoing respiration issues, lorazepam was held, and he was given a 2-minute bolus of intravenous brivaracetam 100mg instead. Post administration, patient's mentation improved with the resolution of the gaze deviation. Continuous video electroencephalogram did not show any electrographic seizures. Patient was continued on brivaracetam 100 mg twice daily.
