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

BACKGROUND: The impact on infectious risk of ultrasound guidance at insertion remains controversial in short-term arterial catheters (ACs).

Sumario: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 US exhibited similar risks for MCRI (HR 0.86, CI 95% 0.27–2.72, p = 0.79), CR-BSI (HR 0.87, CI 95% 0.20–3.72, p = 0.85) and catheter colonization (HR 1.31, CI 95% 0.92–1.86, p = 0.13). After adjustment on confounders, risks associated with US guidance remained similar versus non-US for MCRI (HR 0.71, CI 95% 0.23–2.24, p = 0.56), CR-BSI (HR 0.71, CI 95% 0.17–3.00, p = 0.63) and catheter colonization (HR 0.92, CI 95% 0.63–1.34, p = 0.67). No differences between US and non-US for MCRI, CR-BSI and colonization were observed according to the insertion site, radial or femoral. At catheter removal, the skin colonization was similar between US and non-US groups (p = 0.69). CONCLUSIONS: 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 NCT 01189682).
