Randomized Controlled Trial
Bloodstream infection related to catheter connections: a prospective trial of two connection systems.
Bloodstream infections (BSIs) related to central venous catheters (CVCs) and arterial catheters (ACs) are an increasing problem in the management of critically ill patients. Our objective was to assess the efficacy of a needle-free valve connection system (SmartSite), Alaris Medical Systems, San Diego, CA, USA) in the prevention of catheter-related bloodstream infection (CR-BSI). Patients admitted to an intensive care unit were prospectively assigned to have a CVC and AC connected with either a needle-free valve connection system (NFVCS) or a three-way stopcock connection (3WSC). ⋯ The incidence rate of AC-BSI was 5.00 per 1000 days of catheter use in the NFVCS group, compared with 2.83 in the 3WSC group (P=0.08). The use of NFVCS does not reduce the incidence of catheter-related bacteraemia. The arterial catheter (AC) is a significant source of infection in critically ill patients.
