Abstract: Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope. Materials and methods: A total of 80 obstetric patients were divided into 2 groups, orotracheally intubated with either the McGrath video laryngoscope or the Macintosh laryngoscope. The intubation times, Cormack-Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates were compared among the groups. Results: Intubation time in the McGrath video laryngoscope group was significantly longer than in the Macintosh laryngoscope group (P < 0.01). The percentage of glottic opening was found to be higher in the McGrath video laryngoscope group (P = 0.002). Conclusion: The McGrath Series 5 video laryngoscope provides excellent views during orotracheal intubation in obstetric anesthesia with normal airways.
