Comparison of Lighted Stylet and GlideScope for Double-lumen Endobronchial Intubation

Not Applicable

• Conditions: Intubation;Difficult
• Interventions: Device: GlideScope; Device: Lighted stylet

• Registration Number: NCT03514745
• Lead Sponsor: SMG-SNU Boramae Medical Center

Brief Summary

We evaluate the GlideScope and lighted stylet for DLT intubation in terms of the intubation time, number of intubation attempts, difficulty in DLT advancement towards the glottis, postoperative sore throat and hoarseness, and hemodynamic responses during intubation in patients with predicted difficult airways.

Arm && Interventions

Group	Intervention	Description
GlideScope group	GlideScope	After the induction of anesthesia, endobronchial intubation is performed using the GlideScope.
Lighted stylet group	Lighted stylet	After the induction of anesthesia, endobronchial intubation is performed using a lighted stylet.

Primary Outcome Measures

Name	Time	Method
Intubation time taken for endobronchial intubation	During endobronchial intubation	Intubation time is defined as the time elapsed from picking up GlideScope or lighted stylet to confirmation of successful intubation by capnometry.

Secondary Outcome Measures

Name	Time	Method
Number of intubation attempts	During endobronchial intubation	Total intubation attempts are counted.
Difficulty of DLT advancement towards the glottis	During endobronchial intubation	It is categorised as very easy, easy, difficult, and very difficult
Resistance to DLT insertion through the glottis	During endobronchial intubation	It is categorized as none, mild, and moderate
The incidence and severity of postoperative hoarseness	At 1 and 24 hours after surgery	Hoarseness is defined as a voice quality different from the preoperative voice and graded as follows: none (no hoarseness), mild (recognized by the patient), moderate (obvious to the investigator), and severe (aphonia).
The incidence and severity of postoperative sore throat	At 1 and 24 hours after surgery	It is quantified by using a 100-point numerical rating scale (NRS, 0 \[no pain\], 100 \[worst pain imaginable\]).
