Effect of different sedation on critical flicker frequency, a diagnostik tool for minimal encephalopathy

Introduction: Critical flicker frequency measurements are a valid tool for assessing early stages of cerebral dysfunction in patients with acute and chronic liver diseases. However, it may also serve as a tool for assessing the fitness of these patients after specific diagnostic or therapeutic interventions. Driving after sedation for endoscopic procedures is a matter of debate, in particular since recent results from a large study (Horiuchi et al.
