Treatment and study plan

No. 7 oral airway

Device

the use of 7 cm sized-oropharyngeal airway (Guedel-type color coded oropharyngeal airway, Hudson RCI, Teleflex Medical, Research Triangle Park, NC)

No. 8 oral airway

Device

the use of 8 cm sized-oropharyngeal airway (Guedel-type color coded oropharyngeal airway, Hudson RCI, Teleflex Medical, Research Triangle Park, NC)

No. 9 oral airway

Device

the use of 9 cm sized-oropharyngeal airway (Guedel-type color coded oropharyngeal airway, Hudson RCI, Teleflex Medical, Research Triangle Park, NC)

Primary outcomes

  1. the proportion of patients whose oropharyngeal airway is proper

    Time frame: up to 10 minutes after the start of anesthetic induction

    The oropharyngeal airway will be inserted into the patient's mouth. Investigators will check the laryngeal view using fiberoptic bronchoscope and the adequacy of ventilation after the investigator ventilates the patient using the face mask. If both the laryngeal view and ventilation are appropriate, the size of oropharyngeal airway will be considered as the proper size for the patient.
