Comparison of First Attempt Success Based on Endotracheal Tube Type During Videolaryngoscope-guided Intubation Without Stylet
28 juni 2026 uppdaterad av: Seoul National University Hospital
Comparison of First Attempt Success Based on Endotracheal Tube Type During Videolaryngoscope-guided Intubation Without Stylet: Prospective Non-inferiority Comparison
Patients are randomly assigned to either the oral RAE tube group (Group O) or the reinforced tube group (Group R).
In both groups, tracheal intubation is performed using a videolaryngoscope without a stylet, and the first-attempt success rate is compared.
Upon emergence from anesthesia and removal of the endotracheal tube, the degree of subglottic injury is assessed and compared between the groups.
In addition, postoperative sore throat and hoarseness are evaluated and compared at 1 hour and 24 hours after surgery.

Experimentell: oral RAE tube group
|
Tracheal intubation is performed using a videolaryngoscope without a stylet.
In Group O, an oral RAE tube is used, while in Group R, a reinforced endotracheal tube is used.
Intubation is conducted after induction of general anesthesia.
Upon completion of surgery, the endotracheal tube is removed, and the degree of subglottic injury is assessed.
Postoperative sore throat and hoarseness are evaluated at 1 hour and 24 hours after extubation.

Cormack-Lehane grade and POGO score
Tidsram: Periprocedural (during tracheal intubation)
|
Airway visualisation was assessed during tracheal intubation using the Cormack-Lehane grading system (Grade I-IV, where Grade I indicates full view of the glottis and Grade IV indicates no visible glottic structures; lower grades indicate better glottic visualisation) and the Percentage of Glottic Opening (POGO) score (0-100%, where higher scores indicate better glottic visualisation).
