Brief Summary

**Macintosh laryngoscopes are commonly used for endo tracheal inubation. Video laryngoscopes are commonly used nowadays like CMAC and Smarttrach. We aim to compare the intubation characteristics of these three laryngoscopes in terms of their overall success rates, number of attempts, time taken, haemodnamic changes, need for external laryngeal manipulation and complications**
