入选标准
- •ASA physical class 1 and
- •BMI 18.5-29.9.
排除标准
- •Patient’s refusal to participate in the study.
- •Rapid-sequence induction of anesthesia.
- •Patients requiring rapid-sequence intubation are already at high risk for aspiration; the airway should be rapidly secured with an endotracheal tube and not subjected to repeated or delayed assessment as might occur in the study.
- •Inability to open the mouth due to existing trauma or medical condition, preexisting neck or facial disease causing distortion of the airway, edentulous, and/or a history of difficult intubation.
- •Altered level of consciousness, confusion, or inability to follow commands
- •Preexisting limitation or pain with cervical spine movement.
