Asleep Fiberoptic vs Direct Laryngoscopy Effect on Hemodynamic Stability Using Opioid Free Anesthesia Induction

The goal of this clinical trial is to compare blood pressure and heart rate between the fiberoptic and direct oral intubation using opioid free anesthesia induction. Secondary objectives include comparing the time needed for intubation and the incidence of postoperative sore throat, hoarseness, and upper airway trauma in adults aging between 18 to 55 years, scheduled for elective surgery under general anesthesia. The main question it aims to answer is: Does fiberoptic intubation cause less hemodynamic instability than direct oral intubation using opioid free anesthesia induction?
