Clinical Trial 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effect of trendelenburg and reverse trendelenburg position on the cross sectional area of the internal jugular vein	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.	At time of data collection: physiologic study
