无菌物品有效期影响因素的调查

Influencing factors of valid period of sterile items

目的 探讨影响一次性材料包装的无菌物品有效期的相关因素.方法 将同一批次清洗灭菌后的无菌物品,存放于符合标准储存条件的消毒供应室和与标准储存条件不同的神经病区治疗室、普外病区换药室、门急诊注射室、洁净手术室,每个储存点120件.定期对各储存环境下储存的同一批次的无菌物品进行细菌培养.结果 灭菌后90 d,门急诊注射室的纸塑包装的3件样本有细菌生长;灭菌后105 d,普外病区换药室的纸塑包装的2件样本有细菌生长;灭菌后150 d,普外病区换药室的无纺布包装的1件样本有细菌生长;至180 d实验结束,存放于消毒供应中心、神经病区治疗室、洁净手术室的实验样本均无细菌生长.结论 影响无菌物品的有效期与时间因素相关,还应从多方面对影响无菌物品有效期相关因素进行评估,将规范、行业标准、规定执行到位,才能确保物品质量,防止院内感染发生.

Objective To investigate the related factors that affect the valid period of sterile items. Methods Sterile items after well cleaning and disinfection were stored in the supply room with a standard storage conditions,as well as in different storage conditions such as neural therapy room,general surgery dressing room, outpatient and emergency injection room,clean operating room with 120 items respectively. Bacterial culture was performed regularly on the sterile items in different storage rooms.Results At 90 d after sterilization, 3 sterile items stored in the outpatient and emergency injection room with paper-plastic packaging had the bacterial growth. At 105 d after sterilization,2 samples in the general surgery dressing room with paper-plastic packaging were found to have the bacterial growth. At 150 d after sterilization,1 sample in the general surgery dressing room with non-woven packaging had the bacterial growth. Up to the end of the experiment,no bacterial growth was observed in the sterile items stored in disinfection supply center,neural therapy room and clean operating room. Conclusions The factors that affect the valid period of the sterilized items are related to the time. It is necessary to evaluate influencing factors of the valid period of sterile items from various perspectives. Specification,industry standards and provision should be executed to ensure the quality of the sterilized items and prevent nosocomial infection.
