A Study of Effectiveness of Videolaryngoscopy and Conventional Laryngoscopy in Adult Patients for Orotracheal Intubation

Aim: Present study was carried out to evaluate and compare the laryngeal view and intubation by direct laryngoscopeusing macintosh blade with video laryngoscope in adult patients requiring endotracheal intubation.Material and Methods: This prospective study was carried out at our institute - GUJARAT CANCER SOCIETY MEDICALCOLLEGE, HOSPITAL AND RESEARCH CENTER. Total 100 adult patients for elective surgery under general anaesthesiawere included in this study. Patients were randomly divided in two groups. Each group included 50 patients. Group A:Videolaryngoscopy, Group B : Conventional Laryngoscopy. Hemodynamic changes and SpO2 were noted and recordedduring the procedure at various intervals.Results: Cormack Lehane glottis view is better with videolaryngoscope than conventional Macintosh laryngoscope andis significant statistically. The mean tracheal intubation time was higher, in Group B as compared to Group A. But thedifferences were statistically not significant. The mean rate of failure to intubate was almost similar among both thegroups. The difference was statically not significant. No statistically significant difference was observed in mean arterialBP between the two study groups, at any point time.Conclusion: video laryngoscope offers a better laryngeal view, minimum external maneuvers, less attempts for intubationand provides better hemodynamic response during laryngoscopy and intubation as compare to direct laryngoscopy withMacintosh blade.
