摘要
目的了解全国医院口腔科用水污染状况及原因。方法在黑龙江、吉林、山东、湖北、上海、江苏、浙江和广东8个省市选择二级甲等及以上医院作为国家级监测点,对口腔科手机喷水菌落总数进行监测。结果 2007-2009年共监测30所医院1368份水样,菌落总数中位值为497 CFU/ml,65.72%和49.56%的水样超标,为100 CFU/ml和500 CFU/ml;菌落总数和超标率三级医院高于二级医院,南方医院高于北方医院,差异有统计学意义(P<0.05)。结论口腔科用水普遍存在污染,需加强口腔科用水污染原因及控制措施研究。
OBJECTIVE To understand the status of the water contamination in departments of stomatology in nationwide hospitals.METHODS A total of 30 hospitals above class-2 and grade-A hospitals form Heilongjiang,Jilin,Shandong,Hubei,Shanghai,Jiangsu,Zhejiang and Guangdong were set as the State-level monitoring points.The total cfu of spraying water from handpiece outlet（SWHO） was monitored.RESULTS From 2007 to 2009,1368 samples of SWHO from 30 hospitals were monitored,the median of total cfu was 497CFU/ml,65.72% and 49.56% of the samples were higher than 100 CFU/ml and 500 CFU/ml,respectively.The total bacteria count and the excessive rate of SWHO from the third class of hospitals were significantly higher than from the second class of hospitals,and which from south hospitals were significantly higher than that from north hospitals.The differences were statistically significant.CONCLUSION The microbial contamination of water within the DUWL is universal in the whole country.Research on the reason of contamination and control measures should be strengthened.
