Infraclavicular subclavian vein catheterisation: a randomised controlled trial comparing standard ultrasound guidance and a new needle guidance device
Primary resultResult — go to the resultAbsolute difference +12.6%Authors' conclusion
In ICU patients undergoing subclavian catheterisation, magnetic needle-tracking did not significantly increase overall uncomplicated first-puncture success but reduced the incidence of immediate mechanical complications and procedure failures, with a substantial effect in spontaneously breathing patients.
