A comparison between the GlideScope Video Laryngoscope and direct laryngoscope in paediatric patients with difficult airways - a pilot study.

The GlideScope Video Laryngoscope may improve the view seen at laryngoscopy in adults who have a difficult airway. Manikin studies and case reports suggest it may also be useful in children, although prospective studies are limited in number. We hypothesised that the paediatric GlideScope will result in an improved view seen at laryngoscopy in children with a known difficult airway, compared to direct laryngoscopy. Eighteen children with a history of difficult or failed intubation were prospectively recruited. After inhalational induction, each patient had laryngoscopy performed using a standard blade followed by GlideScope videolaryngoscopy. The GlideScope yielded a significantly improved laryngoscopic view, both with (p = 0.003) and without (p = 0.004) laryngeal pressure. The mean (SD) time taken to achieve the optimal view was 20 (8)s using conventional laryngoscopy and 26 (22)s using the GlideScope (p = 0.5). The GlideScope significantly improves the laryngoscopic view obtained in children with a difficult airway.
