Liu X, Ye H, Zheng X, et al. - A higher risk for catheter-related infections in critically ill patients undergoing continuous renal replacement therapy (CRRT) was observed in relation to catecholamine inotropes use; this was an independent association.

• A single-center retrospective cohort study with critically ill patients needing CRRT.

• Patients who received and did not receive catecholamine inotropes for ≥24 h (catecholamine and control groups, respectively) were analyzed.

• In terms of catheter-related bloodstream infection incidence, no significant between-group difference was found.

• Increased catheter-related colonization risk was noted in relation to catecholamine inotropes use.

• The prominent pathogenic bacteria were gram-negative bacteria.
