Comparison of King Vision Video Laryngoscope to McGrath MAC Video Laryngoscope for Nasal Intubation

Study Overview
=================
Brief Summary
-----------------
This study was designed to determine the comparison between the King Vision video laryngoscope and McGrath MAC video laryngoscope for nasotracheal intubation.Patients were divided into 2 groups of 40 patients each.Patients of King Vision group [n=40]and Macintosh group [n=40]were intubated using respective devices.This study is the first to search the use of King Vision video laryngoscope for nasotracheal intubation in difficult airway.
