Video Laryngoscope Versus USB Borescope in Difficult Intubation

Study Overview
=================
Brief Summary
-----------------
Video Laryngoscope Versus a USB Borescope Aided Endotracheal Intubation in Adults With Anticipated Difficult Airway

Detailed Description
-----------------
For patients allocated to the USB-borescope technique, a proper size endotracheal tube will be placed over the USB-borescope (with an external diameter of 5.5 mm) which will be coated externally with water-soluble lubricant. The proper size laryngoscope blade will be inserted. The USB-borescope will be placed through the oral cavity and will be advanced while tracking it on a mobile phone, it will be advanced to the glottic opening. If needed, rotation of USB-borescope and/or external laryngeal manipulation will be used to align it with the vocal cord. For patients allocated to the intubation over Video Laryngoscope technique, video laryngoscope (Insighters insight is3) proper size blade will be placed and introduction of the Video Laryngoscope till viewing the glottis opening then insertion of a proper sized endotracheal tube
