摘　　要：目的探讨战备消毒包在内陆和高原地区自然环境中的储存时限及细菌的来源。方法准备双层棉布手术敷料包、器械包、敷料器械混合包,预真空压力蒸汽灭菌后分别存放在自然环境战备仓库储存箱内,每个箱内放置3种类型消毒包各3个,分别于灭菌后不同时间,每次每组随机取3种规格消毒包各3个进行细菌培养;同时对战备仓库空气、储存箱进行取样培养并进行细菌同源性研究。结果重庆地区无菌包在灭菌后40 d内均无细菌生长,49 d两个无菌包培养结果为阳性;拉萨地区106 d开放组4个消毒包培养阳性,密闭组培养为阴性;122 d开放组6个、密闭组1个消毒包培养阳性;战备仓库空气和储存箱内优势菌属均为革兰阳性杆菌和革兰阳性球菌。结论不同海拔地区自然环境中战备消毒包的储存时限与当地的自然环境气候密切相关;战备消毒包内细菌来源于空气;规范消毒操作规程,尽可能控制环境诸多因素对微生物的影响,可能延长战备消毒包有效储存时限。OBJECTIVE To investigate the storage time and the origin of bacteria for disinfection package for combat readiness under natural environment in inland and plateau situation.METHODS We prepared double-cotton operation dressing packet,apparatus package,as well as dressing and apparatus mixed packet each with 72 pieces,respectively.Packages were deposited within closed and opened storage boxes under natural environment in depository for combat readiness,respectively after vacuum steam sterilization.Three different kinds of packages each with 3 items were put inside each box.After sterilization,total of 9 items with each 3 from one type of package were taken randomly from each group every time for bacterial culture by different time.At the same time,samples of the air and depot boxes in warehouse for combat readiness were collected and cultured as well as analyzed for bacterial homology.RESULTS In Chongqing,all packages were negative for bacteria on the 40th day after sterilization,while 2 packages were positive for bacteria on the 49th day.In Lhasa,4 packages were positive in opened group on the 106th day after sterilization.On the 122nd day,6 packages were positive in opened group and 1 item was positive in closed group.The dominant bacteria are bacilli and staphylococci both in the air and depot boxes of the warehouse for combat readiness.CONCLUSIONS The storage time for disinfection package under natural environment in different areas correlates closely with the local environmental and climatic situations.The bacteria of the package were confirmed to be from the air.The effective storage time for disinfection package would be prolonged by standardization of the disinfection procedure,and control multiple environmental factors affecting microorganisms.
