Research in relationship between storage method and pollution degree for medical devices after cleaning / 中国实用护理杂志

ABSTRACT

Objective The study aimed to explore the relationship between storage methods and pollution degrees of two different storage methods for medical devices which can not be packed promptly after cleaning.Methods 300 pieces of surgical devices were randomly divided into the experimental group and the control group according to random digit table,150 pieces in each group.Each group was washed with two cleaning machines of the same brand and model number using the same cleaning protocol,and after cleaning,the experimental group was stored in the cleaning machine,while the control group was exposed in the packaging area.Ten hours later,each surgical instrument was detected using ATP biological fluorescence detector.Results The percent of pass in the experimental group was higher than that of the control group [98％ (147/150) vs.86％ (129/150)],x2=12.7,P＜ 0.05.Conclusions Medical devices should better be stored in the washing machine than exposure to the air after cleaning if they could not be packaged and sterilized immediately.
