Summary

Paratracheal pressure may have a role in the prevention of pulmonary aspiration. The effects of paratracheal pressure on glottic view, ease of facemask ventilation, or tracheal intubation are not studied yet. In this study, the subjects are divided into two groups (group I: paratracheal pressure applied during induction of anesthesia, group II: conventional Sellick's maneuver applied during induction of anesthesia). Investigators will assess the glottic view during direct laryngoscopy.

Detailed description

Primary outcome: -Cormack-Lehane grade Secondary outcome: * POGO score before and after application of each intervention * Difficulties of mask ventilation after application of each intervention * Inspiratory pressure and tidal volume during manual mask ventilation * Rates of worsening of the glottic view after intervention * The difficulty of endotracheal intubation * Intubation time

Conditions

• Paratracheal Pressure
• Sellick's Maneuver
• Airway Management
• Cricoid Pressure

Interventions

Type	Name	Description
PROCEDURE	Paratracheal pressure	Paratracheal pressure is applied by 30N force with the ultrasound transducer.
PROCEDURE	Sellick's maneuver	Conventional Sellick's maneuver is applied by 30N force
