三孔聚丙烯输液瓶瓶盖不同消毒方法的消毒效果比较

Comparison of disinfection effects of different disinfection methods for caps of three-porous polypropylene infusion bottles

目的比较瓶塞中心消毒方法和凹槽中心消毒方法对三孔聚丙烯输液瓶瓶盖的消毒效果,探讨三孔聚丙烯输液瓶瓶盖消毒的最佳方法。方法2017年9月至2018年10月选择攀枝花市及成都周边地区10所医院的1088瓶三孔聚丙烯输液瓶进行消毒,分别采用荧光粉迹法和细菌培养法进行效果对比。采用配对实验设计法分别将2种效果监测法的液体分为瓶塞中心消毒组和凹槽中心消毒组,每名护士分别消毒2种监测方法的2组液体。结果凹陷中心消毒方法对272瓶不同规格输液瓶消毒后荧光粉残留总面积中位数(四分位数范围)M(P25,P75)为0.26(0,2.51),瓶塞中心消毒方法消毒后荧光粉残留总面积M(P25,P75)为15(8,24),2组液体瓶消毒后瓶盖荧光粉残留面积差异有统计学意义(Z值为-17.31,P<0.01)。158瓶输液瓶采用瓶塞中心消毒方法消毒后细菌培养的阳性标本数34例、细菌菌落数68个,160瓶输液瓶采用凹槽中心消毒方法消毒后细菌培养的阳性标本数15例、细菌菌落数30个,2组液体瓶消毒后细菌培养阳性率分别为21.52%(34/158)、9.38%(15/160),差异有统计学意义(χ^2值为2.773,P<0.05)。结论凹槽中心消毒方法是三孔聚丙烯输液瓶瓶塞的最佳消毒方法。

Objective To compare the disinfection effect of three-hole polypropylene infusion bottle stopper by central sterilization method and groove central sterilization method,and to explore the best method of three-hole polypropylene infusion bottle cap disinfection.Methods A total of 1088 bottles of three-pore polypropylene infusion bottles from 10 hospitals in Panzhihua City and the surrounding areas of Chengdu were selected for disinfection,and the effects were compared by fluorescent powder tracing method and bacterial culture method respectively.The two methods were divided into two groups:bottle stopper Central Sterilization group and groove Central Sterilization group.Each nurse sterilized two groups of liquid.Results The total area of fluorescent powder residues after disinfection of 272 bottles of infusion bottles with different specifications M(P25,P75)was 0.26(0,2.51).The total area of fluorescent powder residues M(P25,P75)was 15(8,24).There were significant differences in the residual area of fluorescent powder between the two groups after liquid bottle disinfection(Z=-17.31,P<0.01).Thirty-four positive specimens of bacteria culture,68 bacterial colonies and 158 bottles of infusion bottles were disinfected by central sterilization of 160 bottles.There were 15 positive samples and 30 colonies of bacteria cultured in the bottle disinfected by groove central disinfection method(χ2=2.773,P<0.05).Conclusion The groove center disinfection method is the best disinfection method for the bottle stopper of three-hole polypropylene infusion bottle.
