Magnet guidance reduces misplacement of subclavian vein catheter in internal jugular vein

The internal jugular vein (IJV) and subclavian vein (SCV) are the two most commonly used insertion sites for central venous catheterization (CVC). A multicenter clinical trial compared commonly used insertion sites and found that SCV use is associated with a lower incidence of bloodstream infection and deep vein thrombosis than IJV use . Moreover, the SCV is often the best choice in cases of hypovolemia, morbid obesity, and neck trauma . The SCV is also favored by patients because it does not interfere with neck movement and therefore is a better choice for long-indwelling cases. However, one common complication during SCV catheterization is malposition of the tip into the IJV , which not only impairs central venous pressure readings but also may increase the risk of thrombophlebitis. In this study, we tried to evaluate the efficacy of magnet guidance in reducing misplacement of the SCV catheter in the ipsilateral IJV.
The study was registered at Chinese Clinical Trial...
