Effect of Modified Stylet Angulation on the Intubation With GlideScope®

The GlideScope® videolaryngoscope usually visualize glottis better than the conventional laryngoscope. Under the visualization of glottis by GlideScope®, the insertion of endotracheal tube, however, is challenging.

The goal of this study was to determine which of two stylet (70° vs 90°) was better, as determined by time to intubation.

Procedure

Device

Primary outcomes

  1. Time to Intubation

    Time frame: Intraoperative intubation

    Time from the insertion of the Glidescope blade to the measurement of end tidal CO2 (>30 mmHg)

Secondary outcomes

  1. Success Rate of Intubation

    Time frame: Intraoperative intubation

    The number of patients in which the intubation was successful at the first time.

  2. Difficulty of Intubation Measured Using Visual Analogue Scale

    Time frame: Intraoperative intubation

    Difficulty of intubation will be measured using visual analogue scale (0:easiest, 100:most difficult).

  3. Number of Participants for Whom External Laryngeal Manipulation Was Necessary

    Time frame: Intraoperative intubation

    External laryngeal manipulation is defined as the compression of neck for the facilitation of laryngeal view. Number of participants for whom external laryngeal manipulation was necessary will be measured.

  4. Cormack-Lehan Grade

    Time frame: Intraoperative intubation

    The grade of Cormack-Lehan was assessed as I/II/III/IV (I: Full view of glottis, II: Partial view of glottis, III: Only epiglottis seen, none of glottis seen, IV: Neither glottis nor epiglottis seen). Grade I was considered better outcomes.

  5. Mallampati Grade

    Time frame: Intraoperative anesthetic induction

    The Mallapati grade was assessed as I/II/III/IV (I: Soft palate, uvula, fauces, pillars visible, II: Soft palate, uvula, fauces visible, III: Soft palate, base of uvula visible, IV: Only hard palate visible). Grade I was considered better outcomes.

  6. Thyromental Distance

    Time frame: Intraoperative anesthetic induction

    The thyromental distance was measured.

  7. Postoperative Sore Throat Measured Using Visual Analogue Scale

    Time frame: at 1, 24 hr postoperatively

    Postoperative sore throat will be measured using visual analogue scale (0:no pain, 100: worst pain imaginable)

  8. Mean Blood Pressure

    Time frame: Intraoperative intubation

    Mean blood pressure is measured before and 2 min after intubation.

  9. Heart Rate

    Time frame: Intraoperative intubation

    Heart rates are measured before and 2 min after intubation.

  10. Airway Injury

    Time frame: Intraoperative intubation

    Larynx injury is assessed.
