ABSTRACT Objectives:To introduce the clinical experiences of nasotracheal intubation using GlideScope videolaryngoscope and to observe its maneuverability,the clinical values and the related cardiovascular stress responses. Methods:43 patients,ASA Ⅰ~Ⅱ,aged 16~50 years and underwent selective plastic surgery were included in this study. The difficult degree of tracheal intubation was evaluated preoperatively. After rapid sequence induction of anesthesia,nasotracheal intubation was done using GlideScope videolaryngoscope. Noninvasive SBP,SBP,HR and SpO2 were recorded before and after induction,at intubation and every minute for the first 5 minutes after intubation. The times required for visualization of the glottis and successful tracheal intubation,and the Cormack classification of laryngoscopic views were also recorded. Results:The incidence of successful nasotracheal intubation using GlideScope videolaryngoscope in all the patients was 97.7%. The Cormack classification of laryngoscopic views obtained by GlideScope videolaryngoscope were Ⅰ~Ⅱ in all the patients. The times required for visualization of the glottis and successful tracheal intubation were(39.85±12.53)s and(54.71±14.27)s ,respectively. After anesthetic induction,SBP,DBP and MAP decreased significantly as compared with preinduction values. The nasotracheal intubation caused significant increases in SBP,DBP,MAP and RPP in comparison with the postinduction values(P<0.05). The maximal values of DBP,MAP and HR during observation were significantly higher than their preinduction values. However,these hemodynamic changes lasted only 1 to 2 min and then decreased gradually. The values of blood pressure at 4 min or 5 min were even lower than the postinduction values. Conclusions:The advantages of nasotracheal intubation using GlideScope videolaryngoscope are simple manipulation,clear visualization of the glottis and less damage. Because of inherent structure characteristic of GlideScope videolaryngoscope,some special measures must be taken to achieve a successful nasotracheal intubation in clinical practice. The general anesthesia of clinic standard depth can effectively inhibit the adverse cardiovascular stress response to nasotracheal intubation via GSVL.
