Effect of a neck collar on upper airway size in children sedated with propofol-midazolam combination during magnetic resonance imaging

摘要

Introduction: Propofol and midazolam are widely used for pediatric magnetic resonance imaging (MRI) sedation. Increasing depth of sedation may be associated with airway obstruction. A neck collar supporting the mandible and maintaining the head in slight extension may be beneficial in maintaining airway patency.
