Comparison of the effect of upper limb Tourniquet application with Trendelenburg position on diameter and Cross-sectional area of right and left Internal jugular vein using ultrasound in Adult population: a one year prospective Study

Abstract

Background and Aims: Central venous cannulation is essential for administering ionotropes, iv fluid therapy, Central venous pressure monitoring, etc. Larger the vein, easier it is locate and cannulate. Hence, various methods like Trendelenburg position, Valsalva manneuver, passive leg raising are commonly used to increase the diameter and cross sectional area of IJV. In the present study, upper limb venous return was channelized to internal jugular vein by applying tourniquet and change in diameters and CSAs of internal jugular vein bilaterally were compared with Trendelenburg position.
