摘　　要：目的比较蠕动泵辅助采样法及普通冲洗采样法检测软式内镜消毒效果的能力。方法选取该院2019—2021年处理后软式内镜的监测结果,2019—2020年使用普通冲洗采样法收集采样液,2021年使用蠕动泵辅助采样法,比较2种方法的检测合格率、病原菌检出率情况;同时计算用2种方法检测单支软式内镜的经济成本与时间成本。结果蠕动泵辅助采样法检测软式内镜消毒合格率明显低于普通冲洗采样法,分别为78.99%和95.98%(χ^(2)=25.12,P<0.001);病原菌检出率明显增高,蠕动泵辅助采样法及普通冲洗采样法分别为52.10%和17.86%(χ^(2)=34.89,P=0.002),采集一支内镜所需时间由138.73增加到316.73 s(t=6.60,P<0.05),经济成本较普通冲洗采样法增加101.22元。结论蠕动泵辅助采样法检测内镜清洗消毒效果灵敏度高。Objective To compare the effect of peristaltic pump-assisted sampling and conventional irrigation sampling in the quality monitoring of endoscope disinfection.Method The monitoring results of soft endoscopy after treatment in the hospital from 2019 to 2021 were selected.The sampling solution was collected by ordinary washing sampling method in 2019-2020,and the sampling method assisted by peristaltic pump was used in 2021.The qualified rate and the detection rate of pathogenic bacteria were compared between the two methods.At the same time,the economic cost and time cost of detecting a single flexible endoscope by two methods were calculated.Results The qualified rate of soft endoscope disinfection by peristaltic pump-assisted sampling was 78.99%and 95.98%,respectively,which was lower than that by ordinary irrigation sampling(χ^(2)=25.12,P<0.001).The detection rate of pathogenic bacteria was significantly increased,and the peristaltic pump-assisted sampling method and ordinary irrigation sampling method were 52.10%vs 17.86%(χ^(2)=34.89,P=0.002),respectively.The time cost of collecting an endoscope was increased from 138.73 s to 316.73 s(t=6.60,P<0.05).The economic cost was 101.22 yuan more than that of ordinary washing sampling method.Conclusion The peristaltic pump assisted sampling method is highly sensitive to detect the cleaning and disinfection effect of endoscopy.
