AbstractVideolaryngoscope is useful in patients with difficult airways, but it may not be in some patients. We report the use of a lighted stylet to facilitate tracheal intubation in 2 patients in whom laryngoscopy with a videolaryngoscope was difficult. Case 1: A 52-year-old female with loose teeth and lockjaw presented for a scoliosis surgery under general anesthesia. Laryngoscopy using a blade 3 of a Glide-Scope® (Laerdal Medical Corporation, New York, NY, USA) videolaryngoscope (GVL) showed a Cormack-Lehanne grade 3 view. Bag mask ventilation was easily achieved. By using the Trachilight™ (Saturn Biomedical System Burnaby, BC, Canada) with the GVL, we could intubate the trachea succesfully. Case 2: A 16-year-old male with a history of difficult tracheal intubation due to a limited cervical spine movement presented for an external fixation of a femur under general anesthesia. After induction of anaesthesia, bag mask ventilation was easily achieved but the GVL laryngoscopy did not provide a good view of the glottis (Cormack-Lehanne grade 3). Combined use of the Trachilight™ with the GVL, facilitated tracheal intubation. The Trachilight™ is a recognized aid to facilitate trachal intubation but the device is now commercially not available. Neverthless, we believe that a lighted stylet is potentially useful for tracheal intubation when the view of the glottis with a videolaryngoscopy is not ideal.
