About

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.
