Comparison of First Attempt Success Based on Endotracheal Tube Type During Videolaryngoscope-guided Intubation Without Stylet

2026年6月28日 更新者：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.

参与者组/臂
干预/治疗
实验性的：oral RAE tube group
设备：endotracheal tube
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.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
First-attempt success rate of tracheal intubation
大体时间：Immediately after induction of anesthesia
The proportion of patients in whom tracheal intubation is successfully completed on the first attempt using a videolaryngoscope without a stylet, comparing the oral RAE tube group with the reinforced tube group.
Immediately after induction of anesthesia

次要结果测量

结果测量
措施说明
大体时间
Incidence and grade of subglottic airway injury
大体时间：Immediately after completion of surgery (at extubation)
Assessed using flexible bronchoscopy at the time of extubation; graded on a 0-3 scale
Immediately after completion of surgery (at extubation)
Postoperative sore throat score
大体时间：1 hour and 24 hours postoperatively
Sore throat severity assessed using the Numeric Rating Scale (NRS, 0-10) at 1 and 24 hours after surgery.
1 hour and 24 hours postoperatively
Incidence of postoperative hoarseness
大体时间：1 hour and 24 hours postoperatively
Binary evaluation (presence or absence) of hoarseness at 1 and 24 hours after surgery.
1 hour and 24 hours postoperatively
Cormack-Lehane grade and POGO score
大体时间：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).
Periprocedural (during tracheal intubation)
Mean blood pressure
大体时间：Periprocedural (immediately before and immediately after tracheal intubation)
Periprocedural (immediately before and immediately after tracheal intubation)
Heart rate
大体时间：Periprocedural (immediately before and immediately after tracheal intubation)
Periprocedural (immediately before and immediately after tracheal intubation)
Oxygen saturation
大体时间：Periprocedural (immediately before and immediately after tracheal intubation)
Periprocedural (immediately before and immediately after tracheal intubation)
Bispectral index
大体时间：Periprocedural (immediately before and immediately after tracheal intubation)
Periprocedural (immediately before and immediately after tracheal intubation)
