血流感染概述
血流感染(bloodstream infection,BSI)指的是患者血液中存在病原微生物,伴或不伴有感染的症状和体征。除单纯性血流感染外,血流感染还包括感染性心内膜炎、导管相关性血流感染等复杂性感染。血流感染可以是继发于其他部位的感染,如肺部感染、腹腔感染等,也可以是原发性感染,是危及人类生命的全身性感染疾病。当这类患者的感染源控制延迟、抗感染治疗不及时的时候,治疗效果通常很[1]。引起血流感染的病原微生物包括细菌、真菌及病毒,可导致菌血症、败血症和脓毒症,严重者可引起休克、播散性血管内凝血(DIC)、多脏器功能衰竭乃至死亡。近年来,随着侵入性操作的不断增加及广谱抗菌药物、糖皮质激素等药物的大量应用,BSI的发病率及病死率逐年上升[2]。
