摘要
目的了解新生儿重症监护病房(NICU)环境细菌学状况,控制医院感染发生率。方法分别对NICU消毒前后的室内空气、物体表面、医护人员手以及消毒液进行采样检测,并采用法国生物梅里埃公司ATB系统对细菌菌种进行鉴定。结果消毒前合格率室内空气为62.4%、物体表面为51.0%、医护人员手为46.9%、消毒液为100.0%,检测到大肠埃希菌、表皮葡萄球菌、粪肠球菌、酿脓链球菌、溶血葡萄球菌、铜绿假单胞菌、鲍氏不动杆菌等;消毒后合格率室内空气为87.2%、物体表面为90.2%、医护人员手为84.4%,检测到大肠埃希菌、表皮葡萄球菌、粪肠球菌、酿脓链球菌等条件致病菌;消毒前、后质量监测合格率,差异有统计学意义(P<0.05)。结论医疗机构应加强NICU的消毒质量监测,及时发现存在问题,采取有效措施,预防医院感染的发生。
OBJECTIVE To investigate the bacteriological epidemiology in neonatal intensive care units（NICU）so as to achieve better control of nosocomial infections.METHODS The indoor air,objects′ surface,hands of the medical staff and the disinfectants were sampled for the detection,the bacterial identification was performed by BioMerieux ATB Microorganisms analysis system.RESULTS The qualified rates before the disinfection of the indoor air,objects’ surface,hands of the medical staff and the disinfectant were 62.4%,51.0%,46.9% and 100.0%,respectively,Escherichia coli,Staphylococcus epidermidis,Enterococcus faecalis,Streptococcus hemolytic,S.haemolyticus,Pseudomonas aeruginosa and Acinetobacter baumannii were identified;the qualified rates after the disinfection of the indoor air,objects’ surface,and hands of the medical staff were 87.2%,90.2%,and 84.4%,the opportunistic pathogens like E.coli,S.epidermidis,E.faecalis,and S.hemolytic;the difference in the qualified rate before and after disinfection was statistically significant（P〈0.05）.CONCLUSION The monitoring of disinfection quality in NICU should be strengthened in order to find the problems in a timely manner and take effective measures to prevent nosocomial infections.
