Relationship between Trendelenburg tilt and internal jugular vein diameter.

OBJECTIVES To evaluate the relationship between Trendelenburg tilt and internal jugular vein (IJV) diameter, and to examine any cumulative effects of tilt on the IJV diameter. METHODS Using a tilt table, healthy volunteers were randomised to Trendelenburg tilts of 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees. Ultrasound was used to measure and record the lateral diameter of ...

Effect of Trendelenburg position on right and left internal jugular vein cross-sectional area

BACKGROUND Unlike the right internal jugular vein (RIJV), there is a paucity of data regarding the effect of the Trendelenburg position on the left internal jugular vein (LIJV). The purpose of this study is to investigate the cross-sectional area (CSA) of the LIJV and RIJV and their response to the Trendelenburg position using two-dimensional ultrasound in adult subjects. METHODS This study e...

No enlargement of the right internal jugular vein of the dialysis patients in the Trendelenburg position.

BACKGROUND The Trendelenburg position has been suggested for right internal jugular vein (RIJV) catheterization. However, this position can sometimes be functionally intolerable for chronic kidney disease patients. We conducted an ultrasound study to further investigate the efficacy of the use of the Trendelenburg position during tunneled dialysis catheter insertion via the RIJV in chronic kidn...

The position of the tourniquet on the upper limb.

Our aim was to determine if a tourniquet placed on the forearm has any advantage in clinical practice over the usual position on the upper arm. We randomised 50 patients who were undergoing an open operation for carpal tunnel syndrome under local anaesthesia into two groups. One had a tourniquet on the upper arm and the other on the forearm. The blood pressure, pulse, and level of pain were rec...

EF FECTS OF THE VALSALVA MANEUVER AND HEAD ROTATION ON INTERNAL JUGULAR VEIN DIAMETER AND LOCATION BY ULTRASONOGRAPHY

In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...
