title: [Impact of the use of luer access devices on the quality of chronic hemodialysis].
abstract: Luer access valves are medical devices used to reduce infectious risks by securing repetitive handling in chronic hemodialysis using central catheter. Their impact on the effectiveness of a hemodialysis session still remains poorly studied. This in vivo study aims to evaluate its effectiveness. Tego(®) and Q-Syte(®) valves were used in alternation for each patient for four weeks (428 hemodialysis sessions). The two-luer access valves have led to a significant increase in the dysfunction of the hemodialysis sessions (51.8% compared to the usual care (39.3%) (P=0.012). The analysis by sub-category suggests a heterogeneous behavior of the two devices. The Q-Syte(®) valve showed significantly more dysfunction than the Tego(®) valve or the absence of valve. However, both valve systems tested can maintain the performance of the hemodialysis session as they don't change the dose of dialysis. This study highlights that an evaluation of each device must be performed prior to their use to assess the risk-benefit balance.
