RESUMO
Objective:To improve the loading technology of precision micro instruments, so as to ensure not only the quality of cleaning and sterilization, but also the safe use of instruments.Methods:From January to March, 2021, 80 sets of precision micro instruments from Sterilization Supply Center, Shanghai Jiao Tong University School of Medicine Affiliated Ruijin Hospital were randomly divided into silica gel pad loading group (group A) and silica gel stent loading group (group B), 40 sets in each group. The cleaning effect, drying effect, loading effectiveness and sterilization wet bag of the instruments in the two groups were compared, and the staff of the disinfection supply center were satisfied with the operation of the loading technology of the instruments in the two groups.Results:The qualified cleaning numbers of the instruments in group A and B were 37 and 39 respectively, and there was no significant difference between the two groups ( χ2 = 1.05, P>0.05). The qualified drying numbers in the group A and B were 29 and 38 respectively, the difference between the two groups was significant ( χ2 = 7.44, P<0.05). The effective number of loading in the group A and B were 30 cases and 39 cases respectively, the difference was significant between the two groups ( χ2 = 8.54, P<0.05). The number of sterilized wet bags in the group A and B were 6 cases and 0 cases respectively, the difference was significant between the two groups ( χ2 = 6.49, P<0.05). The satisfaction of 44 personnel in the disinfection supply center with the operation of loading technology were 36 and 43 respectively, the difference was statistically significant between the two groups ( χ2 = 6.07, P<0.05). Conclusion:Loading precision micro instruments with silica gel stent can not only ensure the cleaning and sterilization quality of instruments, but also make the loading of instruments more safe and stable, greatly improve the working efficiency of instrument treatment and accelerate the turnover efficiency of instruments.
RESUMO
Objective To improve the cleaning and loading technology of nasal endoscope in order to ensure the cleaning effect, to improve the working efficiency, and to reduce the cleaning cost. Methods A total of 480 reusable contaminated nasal endoscopes were divided into two groups according to random number table: Clean and load the nasal endoscopes (group A) with the usage of metal parts to open up the leaf; Clean and load the nasal endoscope (group B) with the usage of screw driver to open up the leaf. Each group has 240 pieces. After mechanical cleaning, observe and analyze the cleaning effect, loading effectiveness, loading capacity, loading time and CSSD operators′ degree of satisfaction. Results The number of qualified cleaning joint parts of the two groups were 218 and 231 respectively, and the number of qualified cleaning leaf of the two groups were 214 and 227 respectively, and there were significant differences between the two groups (χ2= 5.828, 4.717, P < 0.05). The number of effective cleaning and loading 211 and 240 respectively, and there were significant differences between the two groups (χ2=30.865, P < 0.01). The time it takes for loading were(2.89 ± 0.22)s/piece and (1.80 ± 0.21)s/piece respectively, and there were significant differences between the two groups. There were significant differences between the two groups (t=55.535, P<0.01). Among 62 CSSD operators, there were 51 and 59 operators in the two groups are satisfied, and there were significant differences between the two groups (χ2=10.806, P<0.05). Conclusions Using the screw driver of the nasal endoscope helps to keep the leaf open during the process of mechanical cleaning, to ensure the cleaning effect, to shorten the loading time and increase the loading capacity. Thus improving the working efficiency and reducing the cleaning cost.
