摘要
目的探讨应用真空包装技术保存无菌包,以延长无菌包保存的有效期。方法无菌包420个,210个为试验组,按无菌技术操作原则的要求,应用真空包装技术对无菌包进行包装后保存;余下210个为对照组,按常规包装后保存;两组包装同时存放无菌柜内,定期各抽30个包进行细菌培养。结果无菌包在保存后试验组第8个月开始长菌、对照组第1个月开始长菌,对照组无菌包经保存后细菌培养阳性率明显高于试验组,两者比较差异有显著的统计学意义(P<0.01)。结论应用真空包装技术对无菌包进行包装保存,延长了无菌包保存的有效期,保存时间可至6个月。
OBJECTIVE To explore the effect of vacuum packaging technique for storing sterilized packs in order to extend the period of valid storing. METHODS From 420 sterilized packages 210 were randomly taken as a test group, and the other 210 packages as the control group. According to aseptic techniques the packages of test group were vacuumized and the control group was packed as by outine protocol. Two groups were simultaneously stored in aseptic closet, and then regularly taken out 30 samples from two groups respectively for microbial culturing. RESULTS Bacterial growth was seen in the control group at first month. But none of the specimens in test group showed any microbial growth until the eighth month. There was a statistically significant difference （P〈0.01） in the incidence of bacterial growth between the two groups, the incidence of bacterial growth in the control group was higher than in the test group. CONCLUSIONS Sterilized packages with vacuum packaging technique can extend valid period, the packages can be stored safely for at least 6 months.
