The Comparison of the Effect of Pressure-controlled Ventilation and Volume-controlled Ventilation on the Gastric Insufflations in I-gel

Yonsei University68 enrolled

Overview

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.

Conditions

General Anesthesia

Interventions

Volume-controlled ventilationOTHER

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.
