Brief Summary

Obesity is associated with difficult intubation rate of 30%, and this study was performed to compare the use of McCoy laryngoscope and C-MAC D-blade video laryngoscope for intubation in obese patients. A total 104 patients with body mass index (BMI) ≥ 35kg/m² scheduled for general anesthesia were randomly assigned to be intubated with McCoy laryngoscope or C-MAC D-blade video laryngoscope. The primary outcome was intubation time, and secondary outcomes were mask ventilation scale, intubation difficulty scale (IDS), percentage of glottis opening (POGO) score, and hemodynamic variables including mean arterial pressure, heart rate and saturation.

Outcome Measures

Primary Outcomes (1)

• Intubation time

  Timing measurement began when the laryngoscope blade was inserted in patients' mouth and ended when end tidal carbon dioxide tracing was detected in the monitor.

  The patients were excluded in this study if intubation time was over 90 seconds.
