A Nontraditional Approach for Awake Fiberoptic Nasotracheal Intubation.

The goal of this clinical trial is to learn if awake nasotracheal fiberoptic intubation through an endotracheal tube inserted in the nasopharynx would be quick and have fewer complications than the conventional technique. The main questions it aims to answer are: which technique of intubation is faster, with more patient comfort and satisfaction? which technique has fewer complications like cough, bleeding, and laryngospasm? Researchers will compare intubation with the conventional fiberoptic technique for intubation to awake nasotracheal fiberoptic intubation through an endotracheal tube inserted in the nasopharynx. Participants will be monitored throughout the procedure for: 1. The duration of the intubation procedure 2. The mean peripheral oxygen saturation 3. Hemodynamic variables (HR, MAP)
