Modified combined short and long axis method (MCSL) for safe internal jugular vein catheterization

Real-time ultrasound-guided internal jugular vein (IJV) catheterization has become a standard procedure as it yields a higher success rate and fewer mechanical complications compared with an anatomical landmark technique [1]. When we use the out-of-plane approach, the adjacent relationship between the IJV and the surrounding structures can be clearly visualized, but the good hand–eye coordination ability and technical skills are required to track the "tip" of the needle in the image [4]. [...]due to the use of long-axis views, the implementation of MCSL technique may be limited in patients with short necks.Funding This work was supported by Science and Technology Bureau joint Health Bureau, Chongqing, China [grant numbers:2021MSXM177].Disclosures This work was supported by Science and Technology Bureau joint Health Bureau, Chongqing, China [grant numbers: 2021MSXM177].Declaration of Competing Interest The authors declared no conflict of interest.Acknowledgements To the Science and Technology Bureau joint Health Bureau, Chongqing, China for funding this study.
