研究组 & 干预措施
Cricoid pressure
Cricoid pressure is applied in the anesthetized state and during video laryngoscopy
干预措施: Maneuvers for occluding esophagus (Other)
Paratracheal pressure
Paratracheal pressure is applied in the anesthetized state and during video laryngoscopy
干预措施: Maneuvers for occluding esophagus (Other)
结局指标
主要结局
Occlusion of the esophagus
时间窗: During 1 minute under videolaryngoscopy
Occlusion of the esophagus is checked with the application of cricoid and paratracheal pressures using esophageal stethoscope. If the esophageal stethoscope is not advanced into the esophagus, it is considered 'occlusion'.
次要结局
- Position of the upper oesophagus relative to the trachea(During 1 minute after injection of anesthetics during induction of anesthesia and during videolaryngoscopy)
- Outer diameter of the esophagus(During 1 minute after injection of anesthetics during induction of anesthesia)
- The best laryngeal view(Before and after the application of cricoid and paratracheal force during videolaryngoscopy)
- Position of the oesophageal entrance relative to the glottis(During 1 minute after injection of anesthetics during induction of anesthesia and during videolaryngoscopy)
