Internal Jugular Vein Cross Sectional Area
Completed
- Conditions
- Central Venous Pressure
- Registration Number
- NCT01099254
- Lead Sponsor
- University of Iowa
- Brief Summary
The Trendelenburg position is used to distend the central veins, improving both success and safety of vascular cannulation. The purpose of this study is to measure the cross-sectional area of the internal jugular vein (IJV) in three different positions, using surface ultrasound.

- Primary Outcome Measures
Name Time Method Effect of trendelenburg and reverse trendelenburg position on the cross sectional area of the internal jugular vein At time of data collection: physiologic study There will be substantial anatomic variation in venous size. Further, Trendelenburg positioning will have little impact on venous cross-sectional area in most subjects when compared with supine.
