Design outcomes

Primary

MeasureTime frameDescription
the proportion of patients whose oropharyngeal airway is properup to 10 minutes after the start of anesthetic inductionThe 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.
