Intervention Model

SEQUENTIAL

Paratracheal force for occluding the upper esophagus is evaluated using the up-and-down sequential method.

Primary Study Purpose

PREVENTION

Blinding Strategy

NONE

Participant: masked because the intervention is applied after anesthesia induction Care provider who inserts an esophageal stethoscope under a certain paratracheal force: masked. The amount of applied paratracheal force is not shown to this investigator

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Different paratracheal force

Esophageal occlusion is assessed by inserting an esophageal stethoscope under different paratracheal forces.

Group Type EXPERIMENTAL

Application of paratracheal force

Intervention Type OTHER

An esophageal stethoscope is inserted into the upper esophagus under the application of different paratracheal force in anesthetized and paralyzed patients.
