Popis: Catheter connectors used in hemodialysis patients are those with open caps to manage high blood flows. However, current guidelines for the prevention of catheter infections recommend closed connectors. Tego™ is a closed connector designed to enable high blood flows. We used an in vitro model to compare the efficacy of Tego™ against contamination with that of standard caps in a real-life practice scenario. The model consisted of 200 blood culture bottles (BCB) with an inserted cannula closed either with Tego™ (100) or with open caps (100). BCB were manipulated using two different methods: under aseptic conditions and with gloves contaminated with a 0.05 McFarland Staphylococcus aureus solution. The BCB were incubated at 37 °C under continuous shaking for up to 7 days or until positive. When a BCB turned positive, 100 μL of the fluid was cultured. The positivity rate and time to positivity of the BCB in each method were compared. Overall, 4.0 % of BCB with Tego™ and 52.0 % of BCB with open caps were positive in the sterile model (p
