    摘要:

    目的了解病区环境中多重耐药菌(MDRO)检出情况,为临床预防和控制MDRO传播提供依据。方法某口腔专科医院2012年9月—2014年7月收治MDRO感染患者作为实验组,随机抽取的12例未感染MDRO患者作为对照组,对其周围环境物品表面进行微生物采样和培养,对微生物进行鉴定和药敏试验。结果44例MDRO感染者中,13例患者周围环境中检出相应的MDRO,总体MDRO检出率为29.55%(13/44)。耐甲氧西林金黄色葡萄球菌(MRSA)在环境各物体表面均有检出,检出率为45.45%(5/11),多重耐药鲍曼不动杆菌(MDRAB)检出率为66.67%(2/3),耐甲氧西林表皮葡萄球菌(MRSE)检出率为66.67%(6/9)。MRSA感染患者鼻腔、手MRSA检出率分别为72.73%、54.54%,其陪护人员鼻腔、手MRSA检出率分别为36.36%、18.18%。实验组和对照组周围环境物品细菌菌落数比较,差异无统计学意义(均P>0.05)。结论口腔医院MDRO感染者周围环境物品表面MDRO检出率高于非MDRO感染者,应加强MDRO感染者周围环境的监控、清洁和消毒,预防MDRO医院传播。

    Abstract:

    ObjectiveTo realize the isolation of multidrugresistant organisms (MDROs) from ward environment, and provide evidence for clinical prevention and control of MDRO transmission.MethodsPatients with MDRO infection in a stomatology hospital from September 2012 to July 2014 were as trial group, 12 randomly selected patients without MDRO infection were as control group, environmental object surface in patients’ ward were taken specimens and performed culture, isolated organisms were identified and performed antimicrobial susceptibility testing.ResultsOf 44 patients with MDRO infection, 13 patients’ surrounding environment were detected MDROs, the total detection rate was 29.55%(13/44). The detection rate of methicillinresistant Staphylococcus aureus(MRSA), multidrugresistant Acinetobacter baumannii(MDRAB),and methicillinresistant Staphylococcus epidermidis(MRSE) were 45.45%(5/11), 66.67% (2/3)and 66.67%(6/9) respectively. Detection rates of MRSA from nasal cavity and hands of MRSAinfected patients were 72.73% and 54.54% respectively, from nasal cavity and hands of patients’ caregivers were 36.36% and 18.18% respectively. The difference in bacterial count between trial group and control group was not significantly different (all P>0.05).ConclusionIsolation rate of MDROs from ward environment of MDROinfected patients is higher than that of nonMDROinfected patients, monitoring, cleaning and disinfection for MDROinfected patients’ surrounding environment should be strengthened, so as to prevent the spread of MDROs in hospital.
