Study Overview

Brief Summary

The purpose of this study is to investigate the changes of the oropharyngeal leak pressure of the air-Q self-pressurizing masked laryngeal airway in the different head and neck positions. Moreover, the adequacy of ventilation will be assessed in the different head and neck positions.

Inclusion Criteria

  • •adult patients aged over 20 yrs who are scheduled for surgery under general anesthesia

Exclusion Criteria

  • •anticipated difficult intubation
  • •body mass index more than 30 km/m2
  • •history of gastroesophageal reflux disease
  • •history of esophageal operation
  • •cervical spine disease
  • •mass in the oral cavity or neck

Outcomes

Primary Outcomes

Oropharyngeal leak pressure

Time Frame: Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway

The oropharyngeal leak pressure was measured by closing the expiratory valve of the circle system at fixed O2 flow 3L/min and 40 cmH2O

Secondary Outcomes

  • Peak airway pressure(Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway)
  • Fiberoptic bronchoscope grade(Within 5 minutes after the insertion of the air-q self-pressurizing masked laryngeal airway)
