Comparing Combined Short-Axis and Long-Axis Ultrasound-Guided Central Venous Catheterization update, With Conventional Short-Axis Out-of-Plane Approaches

摘要

Objective: Visualizing the needle tip using the short-axis out-of-plane (SA-OOP) ultrasound-guided central venous catheterization approach is difficult and results in posterior wall puncture (PWP). To improve needle tip visualization in the long-axis view, combining the SA-OOP and the long-axis in-plane approaches has been suggested. The authors, who previously reported on the utility of this technique using a manikin model, examined the feasibility of this novel method (referred to as the combined short-axis and long-axis [CSLA] approach) and compared the CSLA approach with the SA-OOP approach in humans for the present study.
