ABSTRACT
Objective To analyze the present situation of the dental instrument cleaning and disinfection in Hainan province and to explore the management mode of dental instrument cleaning and disinfection which is suitable for the provincial situation .Meth-ods By adopting the stratified random sampling method according to the hospital grades ,24 hospitals in Hainan province were per-formed the questionnaire survey on the cleaning mode of oral instruments ,layout of cleaning and disinfection room ,cleaning method and facilities ,protection measures and training of cleaning staff .Results 14 hospitals (58 .33% ) had the sterilization and supply center for conducting the centralized processing on the dental instruments .The tertiary hospitals and the second-grade hospitals had the independent cleaning and disinfection rooms with the rational layout and professional cleaning staff ;the safeguard facilities had the application in place ,the training of the related cleaning and disinfection work and the cleaning process conformed the require-ment of the standards .Among 10 first-grade and below hospitals ,only 1 hospital(10 .00% ) had the rational layout of cleaning and disinfection rooms ;3 hospitals(30 .00% ) had the professional cleaning staff ;the related training of the cleaning staff was not basi-cally carried out and the safeguard was not in place ,most of the cleaning and disinfection instruments and the cleaning process were not in accordance with the requirements .The qualification rates of instruments cleaning and disinfection in different grades of hospi-tals by the ATP bioluminescence assay were 100 .00% ,90 .00% and 80 .00% .Conclusion The existing problems are general and prominent in the hospitals of the first-grade and below .It is suggested that the regionalized disinfection and supply management mode is implemented for maximally realizing the optimized resource configuration in the disinfection and supply center .
ABSTRACT
OBJECTIVE To discuss the effect of the different methods on the surface disinfection after the non-infected surgery.METHODS The surface of the objects in the operating room after non-infected surgery was monitored which were divided randomly into group A(n:30) and group B(n:30).The samples of group A which wiping with water and of group B which spraying with Dian′er Kang spray disinfectant were collected.RESULTS After using water to wipe the surface of the surgery mattress,the body position mattress,the arm-support,the instrument table,and the standing stool,the numbers of the fall bacteria were(8.96?3.41),(6.87?2.39),(5.75?2.30),(6.80?2.31) and(7.94?3.40)CFU/cm2,respectively.After the method of spraying by Dian′er Kang spray disinfectant,the numbers were(0.56?1.22),(0.65?1.96),(0.50?1.20),(0.70?1.51) and(0.75?1.30)CFU/cm2.There was statistically significant difference between them(P
