Brief Summary
According to previous studies, head and neck rotation reduces the tongue from being rolled back by gravity, which resulted in increasing patency of the upper airway. Therefore, the purpose of this study is to verify whether head and neck rotation increases the first attempt success rate of i-gel™.

Outcome Measures
Primary Outcomes (1)
First attempt success rate
After the first attempt on insertion of i-gel™ without withdrawal or redirection, the effectiveness of the airway is judged based on a square-wave capnograph and no audible leak with peak airway pressures ≥ 10 cmH2O during manual ventilation.
Induction of anesthesia during intraoperative period

Study Arms (2)
Standard method
ACTIVE COMPARATORInsert I-gel™ according to the manufacturer's instruction. Take the sniffing position and gently move the i-gel™ along the hard palate to the soft palate and the posterior oropharynx.
Head-neck rotation
EXPERIMENTALAfter rotating the patient's head and neck to the left maximally, insert the i-gel™ from the right side of the tongue to the midline. When the tip reaches the soft palate and oropharynx positions, turn the head and neck back to the neutral position.
Interventions
Insert I-gel™ according to the manufacturer's instruction. Take the sniffing position and gently move the i-gel™ along the hard palate to the soft palate and the posterior oropharynx.
After rotating the patient's head and neck to the left maximally, insert the i-gel™ from the right side of the tongue to the midline. When the tip reaches the soft palate and oropharynx positions, turn the head and neck back to the neutral position.
