[摘要] 目的 通过对新生儿重症监护室(NICU)院内感染患儿的回顾性分析,分析院内感染的病原菌及感染因素。方法 对2009年1月”2013年10月该院NICU院内感染的98名病例进行回顾性分析。 结果 在此期间该院NICU共收治患儿2056例,有98例发生院内感染,病原菌培养52例阳性,其中革兰阴性菌42(80.8%)例,革兰阳性菌10(19.2%)例,其中肺炎克雷伯菌19(36.5%)例,大肠埃希菌13(25.0%)例,铜绿假单胞菌6(11.5%)例,鲍氏不动杆菌2(3.8%)例,阴沟肠杆菌2(3.8%)例,表皮葡萄球菌5(9.6%)例,溶血葡萄球菌3(5.8%)例,肠球菌2(3.8%)例,出生时胎龄、出生时体重、住院时间和气管插管是主要的感染因素。结论 NICU中患儿院内感染主要病原菌为革兰阴性菌,早产儿、低体重儿、住院时间长和进行气管插管是主要的感染因素。

[Abstract] Objective To analyze the pathogens and infection factors related to nosocomial infection by analyzing the children with nosocomial infection in the neonatal intensive care unit (NICU) retrospectively. Methods 98 cases with nosocomial infection in the NICU of our hospital from January, 2009 to October, 2013 were analyzed retrospectively. Results During this period there were a total of 2056 children treated in the NICU of our hospital, of them, 98 cases had nosocomial infection, and there were 52 cases with culture-positive bacteria, including 42 patients (80.8%) with Gram-negative bacteria, 10(19.2%) patients with Gram-positive bacteria. Of the patients with Gram-negative bacteria, there were 19 cases(36.5%) of klebsiella pneumoniae, 13 cases(25.0%) of Escherichia coli, 6 cases(11.5%) of pseudomonas aeruginosa, 2 cases (3.8%) of acinetobacter baumannii, 2 cases(3.8%) of enterobacter cloacae, 5 cases(9.6%) of taphylococcus epidermidis, 3 cases(5.8%) of staphylococcus haemolyticus...
