General Anesthesia
Conditions
Brief summary
The purpose of this study is to investigate whether the pressure controlled ventilation can reduce gastric insufflation compared to the volume controlled ventilation in patients who were mechanically ventilated with the i-gel.
Interventions
I-gel will be inserted into the patient's mouth. After confirmation of adequate ventilation with the i-gel, the patient's lungs will be mechanically ventilated using the volume-controlled mode with tidal volume 8 ml/kg during surgery.
