Abstract

The aim of this prospective randomized study is to compare intubating laryngeal mask airway (ILMA) with Macintosh laryngoscope (ML) in patients with simulated cervical spine injury, to compare the hemodynamic variables and to see any complications associated with their use in the peri-operative period. Methods: We selected 60 ASA physical status 1 and 2 patients posted for elective surgeries under general anaesthesia. These patients were randomly allocated into two groups of 30 each: Group ML was intubated using Macintosh laryngoscope and Group ILMA was intubated using ILMA. Baseline hemodynamic parameters (BP, HR), 3 min and 5 min post intubation readings and number of attempts taken for successful intubation were recorded. Results: The mean duration of intubation was more in Group ILMA (28.93 +/-8.98 seconds in Group ML vs 74.83 +/-16.03 seconds in Group ILMA) with a P value of <0.01. The rise in hemodynamic parameters was comparatively higher in Group ILMA than in Group ML but it was statistically insignificant. Conclusion: Macintosh laryngoscope is a faster method to secure tracheal intubation than Intubating Laryngeal Mask in patients with cervical collar. The success rate of intubation through Intubating Laryngeal Mask is similar to that of Macintosh laryngoscope.
