Study Overview
Brief Summary
This study aims to compare the effect of paratracheal and cricoid pressure on placement of the i-gel in terms of the success rate of i-gel insertion, time to placement, the rate of optimal position of the device, and difficulty of i-gel placement.

Arms & Interventions
Paratracheal pressure group
After the induction of anesthesia, the i-gel is placed under the application of paratracheal pressure.
Intervention: Placement of the i-gel (Other)
Cricoid pressure group
After the induction of anesthesia, the i-gel is placed under the application of cricoid pressure.
Intervention: Placement of the i-gel (Other)
Outcomes
Primary Outcomes
The success rate of the i-gel placement
Time Frame: Immediately after the placement of the i-gel
Successful placement of the i-gel is determined by proper chest expansion, the presence of a square waveform on the capnogram, absence of an audible leak, and lack of gastric insufflations.
Secondary Outcomes
- Time to placement of the i-gel(Immediately after the placement of the i-gel)
- The rate of optimal position of the i-gel(Immediately after the placement of the i-gel)
- Difficulty of the i-gel placement(Immediately after the placement of the i-gel)
- Peak inspiratory pressure(At 1 minute after the placement of the i-gel)
- Tidal volume(At 1 minute after the placement of the i-gel)
