Intubation;Difficult
Conditions
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.
Interventions
DEVICEGlideScope
Endobronchial intubation is performed using the GlideScope.
DEVICELighted stylet
Endobronchial intubation is performed using a lighted stylet.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 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 \[worst pain imaginable\]). |
| 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). |
