压力蒸汽灭菌对4种包装材料和不同存放条件有效期对比的观察

目的探讨高压蒸汽灭菌物品对不同包装材料和不同存放条件的有效期。方法对医院供应室无菌物品存放间和全院临床科治疗室、换药室、护理柜、急救车内存放的压力蒸汽灭菌物品,采用A、B、C、D法进行无菌试验观察。结果夏季在供应室无菌物品存放间以A、B法存放14 d,C法存放7个月,D法存放8个月无细菌生长,全院临床科治疗室、换药室、护理柜、急救车内压力蒸汽汽灭菌物品以A、B法存放11 d,C法存放6个月,D法存放7个月无细菌生长。结论通过对压力蒸汽灭菌物品的有效期的质控管理,保证了无菌物品安全有效期的合理使用,达到了控制医院感染。

Expiry Date of Sterile Articles Packed by 4 Different Materials and Preserved in Different Conditions after Pressure Steam Sterilizing: An Observation

OBJECTIVE To investigate the expiry date of sterile articles packed by 4 different materials and preserved in different conditions after pressure steam sterilizing. METHODS The bacteria growth of the materials sterilized by pressure steam sterilizing method and stored in the supply department,treatment room,dressing room,nursing cabinet and ambulance vehicle was observed. RESULTS The axenic periods of the sterile materials in the supply department preserved by methods A,B,C,D were 14 days,14 days,7 months and 8 months,respectively in summer;while the sterile periods of the materials in the treatment room,dressing room,nursing cabinet and ambulance vehicle preserved by methods A,B,C,D were 11 days,11days,6 months and 7 months,respectively.
