不同预处理及清洗方法对宫腔吸引管清洗效果比较

Comparison of Cleaning Effects of Different Pretreatment and Cleaning Methods on Uterine Suction Tube

目的对比分析宫腔吸引管采用不同预处理及清洗方法的效果。方法该次研究纳入自2018年4月-2019年7月的1200件宫腔吸引管,其中600件采用传统预处理方法,其他600件采用改进预处理方法,分别将采用传统预护理方法以及改进预处理方法的宫腔吸引管分为甲组(n=150)、乙组(n=150)、丙组(n=150)、丁组(n=150),分别采用不同的清洗方法,对比各组清洗效果。结果甲组传统预处理及改进预处理清洗合格率分别为48.67%、67.33%,乙组传统预处理及改进预处理清洗合格率分别为71.33%、87.33%,丙组传统预处理及改进预处理清洗合格率分别为82.67%、94.67%,丁组传统预处理及改进预处理清洗合格率分别为90.67%、98.67%。改进预处理各组清洗合格率均高于传统预护理各组(P<0.05),改进预处理丁组清洗合格率均明显高于甲乙丙3组,差异有统计学意义(P<0.05)。改进预处理后甲组管内壁带菌率为81.33%、乙组41.33%、丙组27.33%、丁组11.33%。清洗后甲组管内壁带菌率明显高于其他各组(P<0.05),乙组管内壁带菌率高于丙组及丁组(P<0.05),丁组带菌率低于丙组(P<0.05)。改进预处理后甲组管内壁残留血清洗合格率54.00%、乙组82.00%、丙组86.00%、丁组88.67%。与甲组相比,其他各组管内壁残留血清洗合格率均明显更高(P<0.05),乙丙丁3组管内壁残留血清洗合格率组间对比差异无统计学意义(P>0.05)。结论对宫腔吸引管实施冲洗加酶浸泡保湿预处理并于多酶液下进行手工刷洗,联合超声波多酶机洗以及高压喷枪冲洗,最后采用热水及软水漂洗能够保证清洗质量,可有效降低管内壁带菌率并可使管内壁残留血清洗合格率得到显著提高。

Objective To compare and analyze the effects of different pretreatment and cleaning methods for the uterine suction tube.Methods This study included 1200 uterine cavity suction tubes from April 2018 to July 2019,600 of which used traditional pretreatment methods,and the other 600 used improved pretreatment methods.The uterine cavity suction tubes using traditional pre-care methods and improved pretreatment methods were divided into Group A(n=150),Group B(n=150),Group C(n=150),Group D(n=150),adopt different cleaning methods,and compare the cleaning effects of each group.Results The cleaning pass rates of traditional pretreatment and improved pretreatment of group A were 48.67%and67.33%,respectively.The cleaning pass rates of traditional pretreatment and improved pretreatment of group B were71.33%and 87.33%,respectively.The traditional pretreatment and improved pretreatment of group C of the cleaning pass rates were 82.67%and 94.67%,respectively.The cleaning pass rates of traditional pretreatment and improved pretreatment of group D were 90.67%and 98.67%,respectively.The cleaning pass rate of each improved pretreatment group was higher than that of the traditional pre-care groups(P>0.05),and the cleaning pass rate of the improved pretreatment group D was significantly higher than that of the A,B,and C group,the difference was statistically significant(P<0.05).After the improved pretreatment,the bacteria carrying rate in the tube wall of group A was 81.33%,group B was 41.33%,group C was 27.33%,and group D was 11.33%.After cleaning,the infection rate of the tube inner wall of group A was significantly higher than that of the other groups(P>0.05),the tube inner wall rate of group B was higher than that of groups C and D(P>0.05),and the rate of group D was lower than that of group C(P>0.05).After the improved pretreatment,the pass rate of residual blood cleaning on the inner wall of the tube in group A was 54.00%,82.00%in group B,86.00%in group C,and88.67%in group D.Compared with group A,the pass rate of residual blood cleaning on the inner wall of the tube in the other groups was significantly higher(P>0.05),and there was no statistically significant difference in the pass rate of residual blood cleaning on the inner wall of the tube in the three groups of ethylene propylene butyl(P>0.05).Conclusion The uterine suction tube is rinsed plus enzyme immersion moisturizing pretreatment and manually scrubbed under multi-enzyme solution,combined with ultrasonic multi-enzyme machine washing and high-pressure spray gun flushing,and finally rinsed with hot water and soft water can ensure the cleaning quality,which can effectively reduce The bacteria-carrying rate on the inner wall of the tube can significantly improve the qualified rate of cleaning the residual blood on the inner wall of the tube.
