Status Withdrawn

Clinical Trial Summary

In 50 Patients who are undergoing a planned surgical procedure which require a central venous catheter the diameter of the subclavian vein is measured by ultrasound under 6 different conditions.

Clinical Trial Description

In 50 Patients who are undergoing a planned surgical procedure which require a central venous catheter the diameter of the subclavian vein is measured by ultrasound under 6 different conditions. The conditions are

1. neutral positioning, PEEP 0 cm H2O,

2. neutral positioning, PEEP 5cm H2O,

3. neutral positioning, PEEP 10cm H2O,

4. Trendelenburg positioning -20°, PEEP 0 cmH2O,

5. Trendelenburg positioning -20°, PEEP 5 cmH2O,

6. Trendelenburg positioning -20°, PEEP 10 cmH2O After these measurements a central venous catheter is used to measure the central venous pressure. ;
