The aim of this study was to quantify culturable microorganisms on needleless connectors (NCs) attached to peripheral intravenous catheters in hospitalized adult medical patients. Half (50%) of 40 NCs were contaminated with microorganisms commonly found on the skin or mouth. Staphylococcus capitis and Staphylococcus epidermidis were most commonly isolated. Emergency department insertion and higher patient dependency were statistically associated with positive NC microorganism growth. These results reaffirm the need for NC decontamination prior to access.
本研究的目的是对住院成年内科患者外周静脉导管上的无针连接器（NCs）上可培养的微生物进行定量分析。40个无针连接器中有一半（50%）被皮肤或口腔中常见的微生物污染。头状葡萄球菌和表皮葡萄球菌是最常分离出的菌种。急诊科置管以及患者较高的依赖程度与无针连接器微生物生长呈阳性在统计学上相关。这些结果再次证实了在使用前对无针连接器进行消毒的必要性。
