Brief Summary

As increasing tidal volume, the cross sectional area and circumference of Internal Jugular Vein (IJV) could increase. And In the previous study, Trendelenburg position can increase size of IJV. So investigators would compare the cross sectional area, circumference of IJV and peak airway pressure in neutral and Trendelenburg position
