Laryngeal mirror (LM) is an inexpensive, portable, readily available device which can help visualize the vocal cords in difficult airway (DA) situations. We evaluated its use in improving glottic view prior to placing the airway adjuncts in simulated difficult airway.Eighty patients scheduled to undergo elective surgery under general anaesthesia with endotracheal intubation were allocated- Bougie group (Group B) and Stylet group (Group S). Direct laryngoscopy was performed and CL grade III simulated. The glottic view was obtained using laryngeal mirror and Gum Elastic Bougie (GEB)/ Styleted Endotracheal Tube (ETT) inserted under mirror view. Time taken to obtain glottic view in LM and time for successful intubation were noted.Significant improvement in glottic view with LM was observed, with the view improving to Grade I in 76.25% and grade II in 23.75% of patients. Both groups were comparable with respect to number of attempts and success rate (p = 0.55).The success rate was 90% in group B and 95% in group S. Time taken for intubation was less in Group S (52.44 ± 14.23 s vs. 62.805 ± 20.74 s) [p = 0.01]. Hence, overall stylet proved to be a better adjunct with mirror guided intubation.We recommend stylet assisted rather than GEB assisted ET intubation under LM guidance in emergency scenarios. Also, further controlled trials are recommended to know the exact location of the mirror in relation to bulb of the laryngoscope as well as different angles at which it is placed to improve the view and stabilize the assembly.
