The efficacy of a subhypnotic dose of propofol in preventing laryngospasm following tonsillectomy and adenoidectomy in children.

Background: Laryngospasm is a well-known problem typically occurring immediately following tracheal extubation. Propofol is known to inhibit airway reflexes. In this study, we sought to assess whether the empiric use of a subhypnotic dose of propofol prior to emergence will decrease the occurrence of laryngospasm following extubation in children.
