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

ABSTRACT:

Background

The impact on infectious risk of ultrasound guidance at insertion remains controversial in short-term arterial catheters (ACs). The present study investigated the association between ultrasound guidance (US) during AC insertion and major catheter-related infections (MCRI), catheter-related bloodstream infections (CR-BSI) or colonization, using univariate and multivariate marginal Cox model for clustered data. The skin colonization at catheter removal was evaluated to explain our results.

Results

We used individual data from two multicenter randomized-controlled trials (RCTs) that included a total of 3029 patients, 10 ICUs and 3950 ACs. US guidance was used for 386 (9.8%) catheter placements. In the univariate Cox model analysis, AC insertion with US versus without
