Abstract:ObjectiveTo explore effective methods for the first cleaning of metal precision surgical instruments and evaluate the effect to improve the quality of cleaning.MethodsThe 184 newly purchased precision surgical instruments used in departments including Otolaryngology, Thoracic surgery and Orthopedics were selected and divided into two groups. 94 pieces in the control group were treated in the method of soaking in the alkaline detergent with a ratio of 1:100 and a temperature of 60-80 °C for 10 minutes+mechanical cleaning (alkaline detergent program); 90 pieces in the observation group were treated in the method of soaking in the alkaline detergent with a ratio of 1∶100 and a temperature of 60-80 °C for 10 minutes and then manual cleaning+mechanical cleaning (alkaline detergent program). After cleaning the instruments in both groups, the quality of the lumen instruments was checked by methods of visual inspection, illuminated magnifier, white gauze, and white strip. The sterilization packages were also opened again after autoclave sterilization to evaluate the oily waste degradation.ResultsThe pass rates of visual inspection and illuminated magnifier, white gauze and white strip, visual inspection and illuminated magnifier after sterilization, and white gauze and white strip after sterilization in observation group were significantly higher than those of control group (100.00% vs. 94.68%, 98.89% vs. 92.55%, 98.89% vs. 90.43%, 100.00% vs. 91.49%, respectively, P<0.05).ConclusionTo ensure cleaning quality, metal precision surgical instruments should be correctly cleaned before the first use. The method of soaking in alkaline detergent for 10 minutes+manual cleaning+mechanical cleaning (alkaline detergent program) can significantly improve the cleaning quality.
Abstract:ObjectiveTo explore the application and effect analysis of lean management model in orthopedic implant cleaning.MethodsA total of 3465 orthopedic implants in our hospital's exotic medical device package from January to June 2021 were selected, and a total of 1800 orthopedic implants before the implementation of the lean management model from January to March 2021 were used as the control group, and a total of 1665 orthopedic implants after the implementation of the lean management model from April to June 2021 were used as the observation group. The control group was managed conventionally, while the observation group implemented the lean management model based on the control group. The cleaning quality and clinical use satisfaction of the orthopedic implants in the two groups were compared by daily monitoring and ATP fluorescence testing. Results The cleaning pass rate of orthopedic implants in the observation group was 97.67%, higher than that of the control group (92.5%), the difference was statistically significant (P<0.05); the clinical use satisfaction rate of the observation group was 100%, higher than that of the control group (84.2%), the difference was statistically significant (P<0.05).ConclusionThe application of lean management mode can effectively improve the cleaning quality and clinical use satisfaction of orthopedic implants, and is worthy of clinical promotion and application.
Abstract:ObjectiveTo analyze the barrier function and bacterial penetration of different medical packaging materials in surgical instruments in order to reduce the risk of infection.MethodsFrom January to December 2020, the clean operating room of the Second Affiliated Hospital of Fujian Medical University used cotton cloth medical packaging and new reusable long fiber polyester cloth as the research objects. The bacteria penetration experiment (Bacillus subtilis) was conducted under dry and wet conditions respectively, and the impermeability of the two types of medical packaging materials was compared.ResultsThere were bacteria growth on the cotton cloth culture medium plate, and the test bacteria penetrated the sample piece; no bacteria grew on the long fiber polyester cloth culture medium plate, indicating that the test bacteria could not penetrate the sample. Under dry conditions, the total bacterial count of cotton cloth was significantly higher than that of long fiber polyester cloth, and the water permeability was higher. The difference was statistically significant (P<0.01).ConclusionLong fiber polyester cloth has strong barrier function in both dry and wet conditions, low bacterial penetration, high water permeability, and can be used repeatedly.
