Overview
Brief Summary
This study is designed to evaluate the occurrence of gastric insufflation and the critical volume of the stomach after three different modes of positive pressure ventilation during induction (Manual-controlled, volume-controlled and pressure-controlled ventilation)
Detailed Description
Aspiration of gastric contents can be a serious perioperative complication, which can be related to facemask positive pressure ventilation with unprotected airway. Even with low peak airway pressure (\<15 cm H2O) gastric insufflation may occur. Since gastric content and volume assessment is a new point-of-care ultrasound recommended application, the cross-sectional antra area will be measured using ultrasonography before, continuously during facemask ventilation and after intubation.
