Background And AimNasotracheal intubation is the main route to secure the airway in oral and maxillofacial surgery patients. This study was aimed to compare the intubation times and glottis visualization of McGrath video laryngoscope with the Macintosh laryngoscope for routine nasotracheal intubation.Materials And MethodsRecords of seventy-one ASA (American Society of Anesthesiologists) I-II patients were evaluated and allocated into two groups (McGrath video laryngoscope (VL) and Macintosh groups). Intubation times, modified intubation difficulty scale (MIDS) scores, and hemodynamic parameters (heart rate and mean arterial pressure) were compared after the anesthesia induction and the intubation.ResultsMean intubation time in the McGrath group (24.9 ± 5.9 seconds) was significantly lower than that of the Macintosh group (28 ± 6.2 seconds; P = 0.037). Magill forceps were needed less in the McGrath group compared to the Macintosh group (13.89% vs. 42.86%; P = 0.009). Total MIDS scores were similar (P = 0.778). There was no significant difference in the hemodynamic parameters between the groups.ConclusionThe McGrath VL significantly reduced the intubation time and the use of Magill forceps compared with Macintosh direct laryngoscope and can be utilised effectively for routine nasotracheal intubation.
