Assessment of laryngoscopy and intubation using Macintosh direct laryngoscope and Video laryngoscope for nasotracheal intubation in maxillofacial surgeries

Background and Aims: Surgeries for maxillofacial fractures or removal of oral tumors we need nasotracheal intubation because it provides uninterrupted view for the surgery. To make nasotracheal intubation easier in cases of maxillofacial trauma, different types of video laryngoscopes have been developed. we compared the efficacy of the Truview EVO2 video laryngoscope and the Macintosh laryngoscope in patients with maxillofacial surgeries. Considering the Cormack and Lehane grading, Intubation Difficulty Scale (IDS) score and total time taken for intubation. Metarials and Methods : Randomized controlled trial was conducted in sixty patients of ASA grade I and II ,posted for orofacial and ENT surgeries were randomly allocated into two groups,in order to find better laryngoscope require for nasotrachel intubation for elective surgery undergoing in general anesthesia. Results: Laryngoscopy with Truview EVO2 video laryngoscope showed better intubating conditions during intubation in comparision with Macintosh laryngoscope. Conclusion: For nasotracheal intubation, Truview EVO2 video laryngoscope provides better layngoscopic view as compared to Macintosh laryngoscope
