纸塑包装物品在压力蒸汽灭菌时质量保存期限的探讨

Shelf Life of Paper-plastic Packing Items after Steam Sterilization

目的探讨纸塑包装物品压力蒸汽灭菌时在不同时段和不同环境的无菌保存期限。方法于2005年1-12月,1次/月在同一时段抽取存放于供应室、急诊室、产后区的无菌包随机采样做细菌培养,每次抽取各存放区的无菌包10个;无菌包均采用纸塑包装,然后进行压力蒸汽灭菌。结果存放在临床科室的无菌包第9个月开始长菌,在供应室保存的无菌包在第12个月仍无菌生长。结论选择优质的包装材料,确保清洗质量,提供良好的存放环境,减少人为污染,才能保证纸塑包装压力蒸汽灭菌物品保存的质量。

OBJECTIVE To study the shelf life of paper-plastic packing items after steam sterilization in different time and different environment. METHODS From Jan to Dec 2005, monthly take ten samples which deposited in central sterilization supply department, emergency room and postpartum room at the same time for bacterial culture. Every time we took ten sterility packs in each department as mentioned, paper-plastic packing had been adopted for the sterility packs in steam sterilization. RESULTS The sterility packages in clinical departments started to grow bacteria from the 9th month. And packages in supply room had no bacteria even at the 12th month. CONCLUSIONS In order to ensure the sterilization quality of paper-plastic packing with steam sterilization, we should choose high quality package material, ensure the cleaning quality, supply favorable storage environment and decrease the artificial pollution.
