Application Observation of Traditional Manual Cleaning,Ultrasonic Cleaning Disinfectors,and Reduced Pressure Boiling Cleaning Machines in the Cleaning of Endoscopic Instruments in the Sterilization Supply Center
Objective To compare and analyze the application effects of traditional manual cleaning,ultrasonic cleaning disinfectors,and reduced pressure boiling cleaning machines in the cleaning of endoscopic instruments in the sterilization supply center.Methods A total of 800 endoscopic instruments processed by the Sterilization Supply Center of Shangqiu First People's Hospital from February 2022 to August 2023 were selected as the research subjects.According to the actual cleaning methods,they were divided into groups:200 instruments were cleaned manually(Group A),300 instruments were cleaned using ultrasonic cleaning disinfectors(Group B),and 300 instruments were cleaned using reduced pressure boiling cleaning machines(Group C).The cleaning qualification rate,sterilization qualification rate,cleaning time,disinfection cost,and satisfaction of various departments with the instrument cleaning were compared among the three groups.Results The number of qualified cleaned instruments in Group A was 180,with a qualification rate of 90.00%,and the number of qualified sterilized instruments was 180,with a qualification rate of 90.00%.In Group B,the number of qualified cleaned instruments was 289,with a qualification rate of 96.33%,and the number of qualified sterilized instruments was 290,with a qualification rate of 96.67%.In Group C,the number of qualified cleaned instruments was 299,with a qualification rate of 99.67%,and the number of qualified sterilized instruments was 300,with a qualification rate of 100.00%.The differences among the three groups were statistically significant(P＜0.05).There was no statistically significant difference in cleaning time and disinfection time between Group C and Group B(P＞0.05).The cleaning time and disinfection time in Group C and Group B were shorter than those in Group A,with statistically significant differences(P＜0.05).The satisfaction scores of the departments with instrument cleaning were(7.45±0.75)points in Group A,(8.16±0.87)points in Group B,and(8.85±0.92)points in Group C,with statistically significant differences among the three groups(P＜0.05).Conclusion Comparing the three cleaning methods for endoscopic instruments—traditional manual cleaning,ultrasonic cleaning disinfectors,and reduced pressure boiling cleaning machines—it was found that the reduced pressure boiling cleaning machine had the best cleaning effect,with higher cleaning and sterilization qualification rates.It is worthy of application.
