Abstract：Objective To optimize the cleaning process of reusable gynecological and obstetrical surgical instruments, and to explore the impact of different moisture pretreatment methods on the cleaning of reusable gynecological and obstetrical surgical instruments. Methods 〓Totally 1200 sets of contaminated gynecological and obstetrical surgical instruments collected from Dec. 2016 to Mar. 2017, were chosen as the research object. They were randomly divided into two experimental groups(A and B)and the control group according to the moisture pretreatment methods, with 300 sets in each group. Group A and B were respectively sprayed and moisturized with use-activated foam multi-enzyme detergent and moisturizing gel, then processed with automatic cleaning sterilizer. For the experiment group, the contaminated instruments were washed directly by automatic cleaning sterilizer without pretreatment. All the instruments washed and disinfected were examined by means of visual inspection and ATP biology fluorescence test, and the difference value of visual inspection and ATP biology fluorescence test were calculated and compared among three groups. Results 〓The qualified rate of processed instruments of the three groups(control group、group A and group B)were 91.00%, 97.00% and 98.25% by visual inspection, and 87.00%, 92.25% and 94.00% by ATP bioluminescence essay. Conclusion 〓The use-activated foam multi-enzyme detergent and moisturizing gel can significantly improve the cleaning quality of the reusable gynecological and obstetrical surgical instruments, considering price and performance, as well as followed enzyme washing process, so the moisturizing gel is worthy of popularization and application.
