Abstract:

Objective　To evaluate the cleaning effect of multi-enzyme pretreatment solution combined with ultrasonic cleaning on straw of gynecological abortion. Methods　It was a experimental study. A total of 1 200 straws of gynecological abortion in central sterile supply department of Shenzhen Nanshan District Maternal and Child Health Hospital from January to June 2022 were selected and were randomly divided into two groups. The control group was given multi-enzyme pretreatment solution combined with manual cleaning, while the experimental group was given multi-enzyme pretreatment solution combined with ultrasonic cleaning. The visual observation method and adenosine triphosphate (ATP) biofluorescence detection method were used to compare the qualified rate of cleaning between the two groups. χ² test was used. Results　By the visual observation method, it was found that the qualified rate of straw cleaning in the experimental group was 93.67% (562/600) and that in the control group was 73.33% (440/600), with a statistically significant difference (χ²=90.026, P<0.001). By the ATP biofluorescence detection method, it was found that the qualified rate of straw cleaning in the experimental group was 87.16% (523/600) and that in the control group was 68.67% (412/600), with a statistically significant difference (χ²=59.672, P<0.001). Conclusion　The cleaning effect of multi-enzyme pretreatment solution combined with ultrasonic cleaning is better than that of multi-enzyme pretreatment solution combined with manual cleaning.

摘要：

目的　评价多酶预处理溶液联合超声清洗对人流吸管的清洗效果。方法　本研究为实验性研究。选取2022年1月至6月深圳市南山区妇幼保健院消毒供应中心收取的1 200支人流吸管作为研究对象，随机分为两组，分别用多酶预处理溶液联合人工清洗（对照组）和多酶预处理溶液联合超声清洗（实验组）处理，采用目测观察法及三磷酸腺苷（ATP）生物荧光检测法比较两组人流吸管清洗合格率。采用χ²检验。结果　通过目测观察法发现，实验组人流吸管的清洗合格率为93.67%（562/600），对照组人流吸管的清洗合格率为73.33%（440/600），差异有统计学意义（χ²=90.026，P<0.001）。通过ATP生物荧光检测法发现，实验组人流吸管的清洗合格率为87.16%（523/600），对照组人流吸管的清洗合格率为68.67%（412/600），差异有统计学意义（χ²=59.672，P<0.001）。结论　多酶预处理溶液联合超声清洗相较于多酶预处理溶液联合人工清洗对于人流吸管清洗效果更佳。
