Yonsei University
  Purpose
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

Condition Intervention
General Anesthesia Surgery Other: Tidal Volume

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: Effects of Increased Tidal Volume on Internal Jugular Vein Cross-sectional Area
