    AbstractIn a randomised controlled study, we compared the ease of railroading a GlideRite® nasal tracheal tube over a fibrescope with that of a pre-rotated RAE™ nasal tracheal tube. We studied 110 anaesthetised patients with no known airway difficulties undergoing elective dental or maxillofacial surgery. Impingement was more common with the GlideRite tubes (11/55 (20%)) compared with the pre-rotated RAE tubes (3/55 (5%); p=0.02). The median (IQR [range]) time to intubation (GlideRite 7.6 (4.7-10.8 [3.0-46.2]) s; RAE 8.0 (6.2-10.7 [2.4-30.0]) s) and postoperative sore throat numerical ratings (GlideRite 2 (0-3 [0-10]); RAE 2 (0-5 [0-8])) were similar. A 90° anticlockwise pre-rotation of a standard nasal RAE tube has a higher initial rate of successful railroading at first attempt and is therefore superior to a GlideRite nasotracheal tube during nasal fibreoptic intubation.© 2011 The Authors.
