Video laryngoscopes resemble traditional laryngoscopes, but they have a video chip embedded in the tip of laryngoscope blade. This enables the operator to "look around the corners" which is not possible with conventional direct laryngoscopes. The present study was undertaken to compare Truview video laryngoscope and Macintosh laryngoscope for glottis visualization, ease of tracheal intubation, and associated hemodynamic response. ⋯ Truview propaganda cum distribution laryngoscope provides a better glottis view than the Macintosh laryngoscope. Although it requires a longer time to intubate using Truview, the overall IDS score was lower as compared to Macintosh laryngoscope. Hemodynamic changes remained similar in both the groups.

Ultrasound is evolving as a probable tool in airway assessment. The upper airway is a superficial structure and has sonographically identifiable structures which makes it ideal for evaluation with the ultrasound. ⋯ Ultrasound measurements of skin to hyoid bone and skin to thyrohyoid membrane distance fail to eclipse clinical parameters in accurately predicting a difficult laryngoscopy.
