A 1 to 5 dilution of 2.5 per cent solution of nebulized racemic epinephrine is given by face mask at atmospheric pressure for approximately one minute immediately after removal of the polyvinyl nasotracheal tube, and then as needed for stridor. Throughout this procedure the heart rate is closely monitored for development of tachycardia, and the nebulization is stopped should the rate go up to 180/min. We are not aware of any controlled study to validate the effectiveness of racemic epinephrine for this purpose, though when given by intermittent positive pressure ventilation it has been beneficial with postextubation croup in children.’ Our clinical
