Ultrasound-guided external jugular vein cannulation for central venous access by inexperienced trainees

The insertion of central venous catheters via the external jugular vein (EJV) is not always practical because of the relatively frequent failure rate; thus, the internal jugular approach is generally used. Data from the literature suggest that ultrasound-guided catheterization of the internal jugular vein is superior to the surface anatomy landmark technique and, therefore, should be the method of choice. We evaluated the value of ultrasound guidance in the learning process of central venous cannulation via EJV by similarly inexperienced trainees.
