We examined the incidence and types of bacterial contamination in 265 infusion set needles in adult critically ill patients. Bacterial contamination was detected in 15 samples (5.7%), and a total of 17 organisms were isolated. Ten were coagulase-negative staphylococci (CNS) and Staphylococcus aureus, and the remainder were α-Streptococcus, Corynebacterium, and gram-negative rods. Although the contamination was not directly related to catheter-related bloodstream infections exchanging infusion bottles can cause intraluminal contamination and is a possible route of these infections.
我们检查了 265 个成人危重病患者的输液套件针中的细菌污染发生率和类型。在 15 个样本（5.7%）中检测到细菌污染，共分离出 17 种病原体。其中 10 种为凝固酶阴性葡萄球菌（CNS）和金黄色葡萄球菌，其余为α-链球菌、棒状杆菌和革兰氏阴性杆菌。虽然这种污染与导管相关血流感染并无直接关系，但更换输液瓶可能会导致管腔内污染，这是这些感染的可能途径之一。
