Abstract: Objective: To compare GlideScope video-laryngscopy and normal laryngoscope to manage complex airway for children with cleft palate. Methods: 60 children undergoing palatoplasty were inclueded in this study. Inclusive criteria was: either sex; age 8-36 months; weight 5-15kg; ASA grade Ⅰ or Ⅱ; Mallampati grade Ⅲ and above. Patients were randomly divided into two groups: normal laryngoscope (group A) and GlideScope (group B). After induction of anesthesia, orotracheal intubation was performed assisted by normal laryngoscope in group A, and by GlideScope in group B. Data collected included Glottis exposure time, intubation time, whether intubation succeeded and cricoid pressing was needed, Cormark-Lehane grade and intubation-ralated injure. Results: The rates of satisfactory glottis exposure and successful endotracheal intubation were significantly higher, the case number of cricoid pressing in group B was less than that in group A (P<0.05). There was no significant difference in the incidence of intubation-related injure and the intubation time between two groups. Conclusion: GlideScope videolaryngoscopy was superior to normal laryngoscope for managing difficult airway.
