Abstract Background: The curved laryngoscope blade described by Macintosh in 1943 remains the most widely used device to facilitate tracheal intubation. The Airtraq® (Prodol Meditec S.A, Vizcaya, Spain) is a new, single use, indirect laryngoscope introduced into clinical practice in 2005. It has wan exaggerated blade curvature with internal arrangement of optical lenses and a mechanism to prevent fogging of the distal lens. A high quality view of the glottis is provided without the need to align the oral, pharyngeal and tracheal axis. We evaluated Airtraq and Macintosh laryngoscopes for success rate of tracheal intubation, overall duration of successful intubation, optimization maneuvers, POGO (percentage of glottic opening) score, and ease of intubation. Materials and Methods: Patients were randomly allocated by computer‑generated random table to one of the two groups, comprising 40 patients each, group I (Airtraq) and group II (Macintosh). After induction of general anesthesia, tracheal intubation was attempted with the Airtraq or the Macintosh laryngoscope as per group. Primary end points were overall success rate of tracheal intubation, overall duration of successful tracheal intubation, optimization maneuvers, POGO score and ease of intubation between the two groups. Results: We observed that Airtraq was better than the Macintosh laryngoscope as duration of successful intubation was shorter in Airtraq 18.15 seconds (±2.74) and in the Macintosh laryngoscope it was 32.72 seconds (±8.31) P
