Anesthesia Intubation Complication
Conditions
Brief summary
In this study, the median paratracheal force for occluding the upper esophagus are evaluated in anesthetized and paralyzed patients using the up-and-down technique.
Interventions
OTHERApplication of paratracheal force
An esophageal stethoscope is inserted into the upper esophagus under the application of different paratracheal force in anesthetized and paralyzed patients.
