Ultrasound guidance and risk for intravascular catheter-related infections among peripheral arterial catheters: a post-hoc analysis of two large randomized-controlled trials.

Using the largest dataset ever collected from large multi-centric RCTs conducted with relatively consistent insertion and maintenance catheter protocols, we showed that the risk of infectious complications for ACs inserted under US guidance is not superior compared to those inserted without US guidance. Trial registration These studies were registered within ClinicalTrials.gov (numbers NCT01629550 and NCT01189682).
