【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。
[Abstract]:Objective to study the storage time and the source of bacteria in the natural environment of inland and plateau areas. Methods the double-layer cotton cloth surgical dressing package, the instrument package, the dressing instrument mixed package, the pre-vacuum pressure steam sterilization, respectively stored in the natural environment war readiness warehouse storage box, each box placed 3 kinds of disinfection bag each 3. At different time after sterilization, each group was randomly selected for 3 kinds of disinfection bags for bacterial culture, and the air and storage box of war readiness warehouse were sampled and cultured and the homology of bacteria was studied. Results the culture results of two sterile bags were positive within 40 days after sterilization, 4 were positive in the 106 days open group in Lhasa, 6 were negative in 122 days in the closed group. The dominant bacteria in air and storage box were Gram-positive bacilli and Gram-positive cocci. Conclusion the storage time of war readiness disinfection bag in natural environment of different altitude is closely related to the local natural environment climate, the bacteria in the war readiness disinfection bag come from air, and the operation rules of disinfection are standardized. It is possible to control the influence of many environmental factors on microorganism and prolong the effective storage time of war readiness disinfection bag.
