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

Abstract

Aim: Present study was carried out to evaluate and compare the laryngeal view and intubation by direct laryngoscope
using 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 MEDICAL
COLLEGE, HOSPITAL AND RESEARCH CENTER. Total 100 adult patients for elective surgery under general anaesthesia
were 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 recorded
during the procedure at various intervals.
Results: Cormack Lehane glottis view is better with videolaryngoscope than conventional Macintosh laryngoscope and
is significant statistically. The mean tracheal intubation time was higher, in Group B as compared to Group A. But the
differences were statistically not significant. The mean rate of failure to intubate was almost similar among both the
groups. The difference was statically not significant. No statistically significant difference was observed in mean arterial
BP between the two study groups, at any point time.
Conclusion: video laryngoscope offers a better laryngeal view, minimum external maneuvers, less attempts for intubation
and provides better hemodynamic response during laryngoscopy and intubation as compare to direct laryngoscopy with
Macintosh blade.
