近年来医院内感染问题日益突出,许多以前罕见的微生物,如多形模仿菌、粒质沙雷氏菌、光滑类酵母菌及红色类酵母菌等渐见于临床血液培养中。经追踪分析,发现静脉输液是医院内感染的重要途径之一。 输液系统中可能污染的重要环节 输液引起败血症是输液系统被细菌或霉菌等病原微生物污染的结果。输液系统中任一组成部分,从液体到插入静脉内的针头或导管均可被污染。按 In recent years, the problem of nosocomial infections has become increasingly prominent. Many previously rare microorganisms such as pleomorphic mimic bacteria, Serratia marcescens, smooth-type yeast and red yeast are gradually seen in clinical blood culture. Tracing analysis found that intravenous infusion is one of the important ways of nosocomial infection. Infusion system may be an important part of the pollution infusion caused by sepsis is the infusion system is contaminated by bacteria or fungi and other pathogenic microorganisms. Any component of the infusion system, from the liquid to the needle or catheter inserted into the vein, can be contaminated. press
