Comparison of First Attempt Success in Nasotracheal Intubation Using Macintosh Videolaryngoscope vs. Flexible Bronchoscope

Comparison of First Attempt Success in Nasotracheal Intubation Using Macintosh Videolaryngoscope vs. Flexible Bronchoscope: a Randomized Controlled Trial

Participants are randomly assigned to two groups: one group undergoes nasotracheal intubation using a videolaryngoscope, while the other group undergoes nasotracheal intubation using a flexible bronchoscope. The primary outcome is the first-attempt success rate, assessed at the time of tracheal tube placement. Additional outcomes include the degree of subglottic injury upon extubation, and the incidence and severity of sore throat and hoarseness at 1 hour and 24 hours postoperatively, as well as overall intubation success rates.

Inclusion Criteria:

• Adults aged 19 years or older
• Undergoing ear, nose, and throat (ENT) surgery requiring nasotracheal intubation

Exclusion Criteria:

• Refusal to participate in the study
• History of gastroesophageal reflux disease
• History of surgery or radiation therapy involving the upper airway
• Presence of severely loose teeth
