Combined Short-Long Axis Versus Medial Oblique Axis for Internal Jugular Vein Cannulation: A Prospective Single-Blinded Randomized Clinical Trial
Authors' conclusion
This study demonstrated the medial oblique axis approach was superior to the CSLA approach regarding first-trial success rate, time to successful line placement, number of attempts, and operator satisfaction when used during elective cannulation of the IJV. However, regarding the incidence of complications, there was no advantage of one approach over the other.
