Nasal Intubation

This study compares two videolaryngoscope blade designs for nasal tracheal intubation in patients undergoing surgery under general anesthesia. Participants will be randomly assigned to undergo nasal tracheal intubation using either a hyperangulated C-MAC® D-BLADE® or a Macintosh-style videolaryngoscope blade. The study will evaluate the effectiveness of each approach by measuring time to successful intubation, number of intubation attempts, airway maneuvers required, and other procedural outcomes. Safety outcomes, including airway- and anesthesia-related adverse events, will also be assessed. The findings may help identify the most effective and safe videolaryngoscope blade design for nasal tracheal intubation.

The goal of this clinical trial is to compare cuff inflation deflation method versus conventional method using Magill forceps in adult patients scheduled for elective surgery dental or maxillofacial that need nasal intubation. The study question: Is cuff inflation deflation method for nasal intubation takes a short time than the conventional method using Magill forceps in adult patients scheduled for elective surgery dental or maxillofacial? We will compare the inflation deflation technique with the Magill forceps technique for nasal intubation in adult patients to see if the inflation deflation technique will take less time and associated with less side effects like cuff perforation and mucosal injury. Participants will \[describe the main tasks participants will be asked to do, interventions they'll be given and use bullets if it is more than 2 items\].
