Editor—Airway management of patients with limited mouth opening remains one of the major challenges in anaesthesia. The fibreoptic intubation is the technique most commonly chosen in such cases, but requires experience to achieve proficiency and is often affected by secretions or blood. It is reported that the failure rate of emergency fibreoptic intubation may be as high as 13%.1 Thus, anaesthetists faced with a difficult intubation may require alternative approaches to fibreoptic or direct laryngoscopy. The GlideScope® (GS) (Saturn Biomedical System Inc., Burnaby, BC, Canada) video laryngoscope may provide a better laryngoscopic view than direct laryngoscopy and is potentially useful for tracheal intubation in patients with a difficult airway.2 3 However,
