简要总结
Comparing the effects of ' Cricoid pressure' or 'Paralaryngeal pressure' during endotracheal intubation procedure.
详细描述
Applying Cricoid pressure is widely used procedure to prevent gastric contents regurgitation during endotracheal intubation. To find out effectiveness external pressure is applied, the investigators will evaluate the relative position of esophagus and trachea. And also comparing the effects of Cricoid pressure and Paralaryngeal pressure during whole tracheal intubation procedures.
- Confirm the relative positions between esophagus and trachea in awake patients by using ultrasonography.
- Compare the effect of 'Cricoid pressure' and 'Paralaryngeal pressure' to esophageal opening during tracheal intubation procedure as below points.
- Awake states. (Before sedation) 2) Anesthetized states. (After muscle relaxation) 3) During direct intubation procedure.

结局指标
主要结局
Occlusion of esophagus
时间窗: for 1 minute during direct laryngosopy
Occlusion of esophagus is checked under the application of cricoid and paralaryngeal pressures during direct laryngsocpy
次要结局
- The relative position of the upper esophageal end to the glottis(1 minute before and after the induction of anesthesia, during direct laryngoscopy)
- The outer anteroposterior diameter of the upper esophageal end(During 1 minute in awake and anesthetized paralyzed states)
- POGO score(during direct laryngoscopy)
