Comparison of Two Blades of Videolaryngoscope in Simulated Difficult Airway in Children

Study Overview
=================
Brief Summary
-----------------
Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The D-blade of videolaryngoscope is preferred in difficult intubation with a more curved blade then the Macintosh videolaryngoscope blade, which may be more useful in difficult intubation. The aim of the study is to compare the D-blade of videolaryngoscope with Macintosh videolaryngoscope blade.
