Abstract: [Abstract] Objective   To compare intubation success rate and safety of two types of video laryngoscopes when used for anesthesia in uvulopalatopharyngoplasty surgery (UPPP) on patients with obstructive sleep apnea syndrome (OSAS). Methods   60 patients undergoing UPPP surgery between January and October of 2013 were selected and randomly divided into McGrath MAC video laryngoscope group (M group), GlideScope video laryngoscope (G group), and SHUCMAN direct laryngoscopy (S group), with 20 patients per group. Mallampati classification scores, Cormack-Lehane grade, intubation success rate, pre-intubation and post-intubation heart rate and blood pressure changes were recorded and compared. Results   Mallampati classification scores were not statistically significant between three groups, Cormack-Lehane grade between M group and G group were also not statistically significant (P>0.05). M and G group had distinct advantages in Cormack-Lehane grade, success rate in intubation, and heart rate and blood pressure at completion of intubation (T3) and 1 minute after intubation (T4), the difference is statistically significant (P<0.05). Recorded blood pressure changes were more stable in G group than M group. Conclusion   The two video laryngoscopes used in anesthesia intubation during UPPP surgery can both effectively reveal the structure of the throat, with high success rate and safety, but in this study the McGrath MAC video laryngoscope was superior to GlideScope video laryngoscope.
