【摘要】：目的监测层流手术室无菌灯柄的消毒效果,分析影响消毒效果的不良因素。方法选择2015年8月-2016年3月手术室使用的190个无菌灯柄,其中百级手术间90个,万级手术间100个。在灯柄开始使用及灯柄使用3、4、5、6 h时对细菌情况进行检测,记录灯柄使用期间手术室流动人数、灯柄使用时间及是否存在血迹。根据有无血迹分为2组进行细菌培养并对比细菌生长情况。结果无菌灯柄在2种级别手术室投入使用时的消毒合格率均为100.00%,在持续使用4 h后均有细菌被检出。影响灯柄消毒效果的因素依次是:存在血迹、流动人数8人/h、暴露时间过长等。有血迹细菌培养的阳性率显著高于无血迹细菌培养的阳性率。结论层流手术室无菌灯柄消毒效果均安全可靠,但在持续使用4 h后开始出现细菌生长;是否存在血迹、手术室流动人数、灯柄使用时间是影响消毒效果的主要因素,应采取相应的防范措施。
[Abstract]:Objective to monitor the disinfection effect of sterile lamp handle in laminar flow operating room and analyze the bad factors. Methods 190 sterile lamp handles were used in operating room from August 2015 to March 2016. Among them, 90 were 100 grade operation room and 100 were 10 thousand grade operation room. When the lamp handle was in use and the lamp handle was used for 6 hours, the bacterial condition was detected, and the number of the operating room, the time of use of the lamp handle and whether there were blood stains were recorded during the use of the lamp handle. According to blood stains, the bacteria were cultured in two groups and the growth of bacteria was compared. Results when the sterile lamp handle was put into use in two kinds of operating rooms, the eligible rate of disinfection was 100.00g and bacteria were detected after 4 hours of continuous use. The factors influencing the disinfection effect of lamp handle were: the presence of blood, the flow of 8 persons / h, the prolonged exposure time and so on. The positive rate of bacterial culture with blood stains was significantly higher than that without blood stains. Conclusion the disinfection effect of laminar sterile lamp handle in laminar flow operating room is safe and reliable, but bacterial growth begins to appear after 4 hours of continuous use, whether there is blood, the number of people in operation room and the time of lamp handle usage are the main factors that affect the disinfection effect. Corresponding precautions should be taken.
