Study on the effect of cleaning da Vinci patient side manipulator with steam cleaner

ObjectiveThis study compares the cleaning effect of patient side manipulators (PSMs) through manual cleaning and steam cleaning.MethodsA total of 2 400 contaminated da Vinci PSMs collected from September 2021 to September 2022 were randomly divided into experimental and control groups, each with 1 200 pieces. The control group adopted manual cleaning, and the steps were rinsing with running water, rinsing with a spray gun, bio-washing, ultrasonic cleaning, rinsing and repeating, drying, and sterilization. The experimental group added steam cleaning between the ultrasonic cleaning and the rinsing and repeating, and other steps remained unchanged. The qualification rates of the two groups were recorded and the damage rates of PSMs during the cleaning process were counted.ResultsThe results of visual inspection and adenosine triphosphate (ATP) bioluminescence assay showed that the qualification rate of the experimental group was higher than that of the control group (P<0.05), and the damage rate of PSM in the experimental group was lower than that in the control group (P<0.05).ConclusionCleaning PSM with steam cleaner significantly reduces the re-cleaning and damage rates and improves cleaning quality.

    Abstract：ObjectiveThe present study explores the application effect of remote supervision in public health and provides a basis for its in-depth promotion using an autoclave sterilization intelligent supervision project in stomatology institutions in Yangzhou, Jiangsu, China.MethodsThe construction and implementation of the autoclave sterilization intelligent supervision project are presented, its advantages and disadvantages of enforcement in public health are analyzed, and recommendations and responses are proposed.ResultsDuring the one-year operation of the project from December 2022 to December 2023, a total of 110 warning data of sterilization equipment were collected, of which 106 were abnormal sterilization durations and 4 were abnormal sterilization temperatures. Autoclave sterilizer biomonitoring reports submitted by medical institutions were reviewed. Five medical institutions were found to violate the law and were investigated and treated following relevant laws and regulations after on-site verification.ConclusionThe autoclave sterilization intelligent supervision project improves the capacity of private and primary medical institutions for the prevention and control of nosocomial infections and thus reduces the risk of infection by further improving the critical early warning system for sterilization in medical institutions, thereby improving the effectiveness of public health supervision.

    Abstract：ObjectiveThe present study aims to explore the effect of intensive disinfection on preventing cluster infection with multidrug-resistant (MDR) Acinetobacter baumannii (AB) in the intensive care unit (ICU).MethodsThe environment where a cluster infection with MDRAB occurred in the ICU was disinfected and monitored before and after disinfection. The test results of target bacteria and non-target bacteria by monitoring were compared.ResultsThe first intensive disinfection resulted in an unsatisfactory evaluation of the implementation effect, with no statistical difference between the target bacteria and non-target bacteria before and after disinfection (P>0.05). After a comprehensive review and introspection, the second intensive disinfection was carried out based on departmental needs. The target and non-target bacteria infected or colonized with MDRAB in the ICU were significantly reduced, and the disinfection effect was statistically significant (P<0.05). However, the target bacteria were detected on sphygmomanometer cuffs and computer keyboards. After the intensive disinfection, no cluster infection occurred within one year thereafter, and the target bacteria remained at a low level.ConclusionIntensive disinfection in an all-around way is an effective means to reduce the risk of infection or colonization with MDRAB in the ICU and cut off the transmission route. However, the effect of intensive disinfection depends on the strict implementation at each step during disinfection. There exist difficulties to be attached importance to in implementing disinfection.
