Children aged below 7 years are randomly assigned to AuraGain Group or I-gel group. After anesthetic induction, AuraGain or I-gel is inserted and mechanical ventilation is started. Oropharyngeal leak pressure, peak inspiratory pressure, success rate for insertion, ease for insertion, ease for gastric tube insertion and fiberoptic bronchoscopic views will be compared between two groups.

Oropharyngeal leak pressure
The airway pressure at which a leak sound is detected around the patient's mouth and at which the airway pressure has reached equilibrium, when the pressure-limiting valve of the anesthesia breathing system is closed and the fresh gas flow rate is fixed at 3 liter/min
Time frame: 30 seconds after AuraGain or I-gel insertion
Peak inspiratory pressure
Peak airway pressure
Time frame: through study completion, an average of 1 hour
Success rate
Success rate of AuraGain or I-gel insertion
Time frame: Within 5 minutes after anesthetic induction
Ease of AuraGain or I-gel insertion
1\. No resistance 2. Moderate resistance 3. High resistance 4. Inability to pass
Time frame: Within 5 minutes after anesthetic induction
Ease of gastric tube insertion
1\. Easy 2. Difficult 3. Unable to pass
Time frame: Within 5 minutes after anesthetic induction
fiberoptic bronchoscopic veiw
1\. No visible glottis 2. Visible glottis and anterior epiglottis 3. Visible glottis and posterior epiglottis 4. Only glottis is visible
Time frame: Within 10 minutes after anesthetic induction
