摘要
目的比较洁净手术室使用前后主要卫生指标的变化,探讨其影响因素,找出改进措施。方法 2015年对成都市内部分洁净手术室进行检测,根据不同使用年限及维护情况将调查的手术室分为新建组、更换组与非更换组,分析3组洁净手术室指标合格率变化情况。结果共检测洁净手术室111间,包括新建组56间,使用超过1年手术室55间,其中更换组24间,非更换组31间。新建组、更换组、非更换组空气洁净度合格率分别为98.21%、100.00%、74.19%,3组比较,差异有统计学意义(P<0.001),其中新建组、更换组空气洁净度合格率高于非更换组,新建组与更换组间比较差异无统计学意义(P=1.000);3组洁净手术室空气细菌浓度、静压差、换气次数比较,差异均无统计学意义(均P>0.05)。结论洁净手术室使用1年后,空气洁净度会降低,静压差、换气次数未发生明显变化,提示在空气细菌浓度指标合格时,仍需留意洁净度超标带来的感染风险,更换洁净手术室高效过滤器能明显改善手术室洁净度状况。
ObjectiveTo compare the main hygiene indicators before and after clean operating rooms are used, evaluate the influencing factors, and find out the improvement measures.MethodsIn 2015, some cleaning operating rooms in Chengdu were detected, according to different service years and maintenance status, operating rooms were divided into newlybuilt group, replacement group, and nonreplacement group, change in qualified rate of three groups of clean operating room indicators were analyzed.ResultsA total of 111 cleaning operating rooms were detected, including 56 newlybuilt operating rooms, and 55 operating rooms （24 in replacement group,31 in nonreplacement group） which have been used for more than 1 years. The qualified rate of air cleanliness in newlybuilt group, replacement group, and nonreplacement group were 98.21%, 100.00%, and 74.19% respectively, difference among three groups was significantly（P〈0.001）, the qualified rate of air cleanliness in newlybuilt group and replacement group were both higher than nonreplacement group, while newlybuilt group and replacement group was not significantly different（P=1.000）；difference in bacterial concentration, static pressure difference, and ventilation frequency of air in operating rooms of three groups were all not statistically significant（all P〉0.05）.ConclusionAfter clean operating room have been used for one year, air cleanliness declined, there was no significant change in static pressure difference and air exchange frequency, which indicates that when concentration of airborne bacteria is qualified, risk of infection due to unqualified air cleanliness still needs to be paid attention, the replacement of high efficiency particulate air filter in clean operating rooms can significantly improve the cleanliness of operating rooms.
