一次性封装袋用于两种灭菌方法的效果比较

Sterile Validity of Euro Steril Disposable Package in Autoclave and Ethylene Oxide Sterilization

目的 比较和确定Eurosteril一次性封装袋在高温高压和环氧乙烷灭菌后的无菌有效期。方法 将 96 0把11号刀片用一次性封装袋通过专用封口机 (Euroseal)进行标准包装。随机分成A和B两组 ,分别经高温高压和环氧乙烷灭菌后 ,定期抽样对刀片进行细菌培养。结果 高温高压组绝对无菌期为灭菌后 7周 ,环氧乙烷组为灭菌后8周。两组间差异有显著性 (P <0 .0 5 ) ,高温高压总体灭菌效果优于环氧乙烷。结论 使用Eurosteril一次性封装袋在高温高压和环氧乙烷灭菌后均能达到至少 7周的无菌有效期 。

Objective To compare and clarify the sterile validity of disposable packages in autoclave and ethylene oxide sterilization.Methods Totally 960 11# scalpels were packed in Euro Steril disposable packages with a Euro seal machine according to the standard procedure.They were divided into A and B groups randomly and sterilized by the autoclave and ethylene oxide, respectively. Samples were submitted regularly for bacterial culture.Results The sterile validity of the autoclave was 7 weeks and that of ethylene oxide was 8 weeks. There was insignificant difference between the two groups (P<0.05).Conclusions Sterile validity of Euro Steril disposable packages in the autoclave and ethylene oxide is at least 7 weeks. The overall sterile outcome of the autoclave was better than that of ethylene oxide.
