The ASA has published its guidelines for central venous access (see link below). I am regularly amused by the slavish credence given by trainees to use of ultrasound as ‘mandatory’ for central venous access. Why I ask? That ‘s what the NICE guideline says, they reply. Do you work in the NHS I ask?
Yes ultrasound has undoubted utility for central venous access at times, and I have made good use of it. But should it be a standard of care? Are landmark-based techniques worth learning in the modern age? The ASA is much more luke-warm about ultrasound, as is the rest of the world! ‘Equivocal’ is the operative term throughout…
Studies show how useful US can be – but that is what the studies were meant to show! They were performed by enthusiastic users of a new technology.
Maybe its our colonial heritage that makes us absorb NICE (and similar) admonitions as if they were coming from a high authority to which we owe allegiance. Incidentally, the best informed UK anesthetists (several of whom with which I have worked) have many amusing things to say about the level of expertise that goes into NICE guidelines. There has also been some thoughtful discussion in recent editions of anesthesia.
