Abstract

Proficiency of use of video laryngoscopes in patients with a normal airway can help us put it use in the emergency. We compared one such Macintosh style video laryngoscope (manufactured by Anesthetics India Pvt. Ltd.) with a direct laryngoscope. After obtaining an informed written consent, the subjects were randomly allocated to one of the two groups. Patients in Group L underwent a direct laryngoscopy with Macintosh Laryngoscope whereas patients in Group K underwent video laryngoscopy, followed by stylet - assisted endotracheal intubation in both the groups.The primary outcome measures were assessment of grade of glottic view using modified Cormack Lehane and POGO Scoring and time to intubation. Results: Demographic variables and pre-operative airway assessment parameters were comparable between the two groups. The p- value of modified Cormack Lehane grading comparing the two groups is 0.331. The mean time to intubation was 42.39 seconds in Group L and 39.39 seconds in Group K with a p value of 0.587. There was no significant difference in of number of intubation attempts, stress response to intubation, incidence of optimization maneuvers required to intubate and complications between the two groups. Conclusion: There is no significant difference in time to intubation, glottic view and incidence of complications between the Macintosh type videolaryngoscopy and direct Laryngoscopy in patients with no anticipated difficult airway and when performed by trained anaesthesia personnel.
