Abstract :

Background Securing the airway is still one of the most important skill in Anaesthesia. Direct laryngoscopy has been universally used for tracheal intubation. To overcome the difficulty in securing the airway, various devices like video laryngoscopes have been developed. We, aim to compare GlideScope video laryngoscope and Macintosh laryngoscope for tracheal intubation. Methods This prospective study was conducted in 60 patients for various surgical procedures. Patients were divided into 2 groups of 30 each Group GL (GlideScope), Group ML (Macintosh). Results Time taken for intubation was significantly higher in group GL (42.76 +/– 7.2) than group ML (29.96 +/– 5.14) with a significant P value of 0.0001. GlideScope provided better Cormack–Lehane view (P value 0.006 grade 1) without significant change in the hemodynamic response. Conclusion Use of GlideScope for tracheal intubation improves the Cormack–Lehane grading, but takes more time than Macintosh laryngoscope without significant change in haemodynamic response.
