An interventional study of Maneuvers for occluding esophagus in Intubation Complication, sponsored by SMG-SNU Boramae Medical Center. Completed at 1 site in Korea, Republic of. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2022-02-10.

Comparing the effects of 'Cricoid pressure' or 'Paratracheal pressure' during direct laryngoscopy
The effectiveness of cricoid pressure and paratracheal pressure for occluding esophagus during direct and video laryngoscopies.
SMG-SNU Boramae Medical Center is the lead sponsor of 38 studies on the registry; 6 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Cricoid pressure is applied in the anesthetized state and during video laryngoscopy
Other: Maneuvers for occluding esophagus
Paratracheal pressure is applied in the anesthetized state and during video laryngoscopy
Other: Maneuvers for occluding esophagus
Cricoid pressure: pressure on the cricoid ring Paratracheal pressure: pressure on the left paratracheal region below the cricoid level
Occlusion of the esophagus
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'.
Time frame: During 1 minute under videolaryngoscopy
Outer diameter of the esophagus
Outer diameter of the esophagus is measured using ultrasound before and after the application of cricoid and paratracheal pressures.
Time frame: During 1 minute after injection of anesthetics during induction of anesthesia
Position of the oesophageal entrance relative to the glottis
Position of the oesophageal entrance relative to the glottis is evaluated.
Time frame: During 1 minute after injection of anesthetics during induction of anesthesia and during videolaryngoscopy
Position of the upper oesophagus relative to the trachea
Position of the upper oesophagus relative to the trachea trachea is evaluated.
Time frame: During 1 minute after injection of anesthetics during induction of anesthesia and during videolaryngoscopy
The best laryngeal view
The best laryngeal view is evaluated using the percentage of glottis opening (POGO) score, ranging from 0% to 100%.
Time frame: Before and after the application of cricoid and paratracheal force during videolaryngoscopy
