【摘要】 目的　探讨避免隔离病区医务人员暴发严重急性呼吸综合征 (SARS)的可能方法。方法　对 2 0 0 3年 1月 3 0日～ 2 0 0 3年 3月 3 0日 ,收治SARS的病房的建筑因素和不同病区内医务人员的被感染情况作分析。结果　A座 12楼 3 1床、15楼ICU层流病房 10床、13楼 2 7床以及B座 14～ 18层同类病房共 3 0间 ,其通风窗户面积与病房空间体积之比依次为 0、0、1∶95、1∶40 (m2 /m3) ;收治患者数依次为 1、1、1、96;患者住院时间依次为 43、168、110、12 72h ;医务人员感染率依次为 73 %、3 2 %、2 8%、2 % ,经卡方检验 ,差异有非常显著性 (P <0 0 0 1)。结论　在严密的个人防护措施前提下 ,以通风窗户面积与病房体积比值大、室内外空气流通好的病房作为收治SARS患者的隔离病区 ,可避免一线医务人员大规模暴发SARS。更多还原

【Abstract】 Objective To investigate measures to prevent the outbreak of severe acute respiratory syndrome(SARS) in healthcare workers in isolation units Methods The architectural factors and the infection of healthcare workers in different wards in our hospital between 30 January 2003 and 30 March 2003 were analyzed Results Four kinds of isolation wards were evaluated,including the ward where the thirty first bed lied in on the twelfth floor,the laminar flow ward in the intensive care unit (ICU) where the tenth bed lied in on the fifteenth floor,the ward where the twenty seventh bed lied in on the thirteenth floor of Building A,and thirty wards on the fourteenth to eighteenth floors of Building B The ratios (m 2/m 3) of the area of the ventilation windows to the volume of the room were 0,0,1∶95 and 1∶40,respectively Numbers of SARS cases in the wards mentioned above were 1,1,1 and 96,respectively The total lengths (hour) of hospitalization were 43,168,110 and 1 272, respectively The infection rates of the healthcare workers in the areas mentioned above were 73%,32%,28% and 2%,respectively The difference of the infection rates was of statistical significance Conclusion In addition to strict personal protective measures,isolation of SARS cases in wards with high ratio of the area of ventilation windows to the volume of the room and good ventilation may be the key to preventing the outbreak of SARS in healthcare workers in isolation units更多还原
