Short versus Long for IJ Cannulation

It is an age-old question - short or long axis? Using ultrasound guidance for internal jugular vein cannulation is now fairly standard.

This episode features a prospective randomized trial that attempts to put an end to this debate. https://www.ultrasoundgel.org/85 https://www.ncbi.nlm.nih.gov/pubmed/31230925
