消化内镜消毒质量与钳子管道组织胶残留的相关性分析

Correlation of disinfection quality of digestive endoscopes with residual tissue glue in forceps channels

目的探讨钳子管道组织胶残留对消化内镜消毒质量的影响。方法随机选取2022年3月—2023年6月本院消化内镜中心使用后的消化内镜103条钳子管道,清洗、消毒后观察内镜钳子管道组织胶残留情况。根据钳子管道组织胶残留情况分为残留组和无残留组,检测2组消化内镜消毒质量及微生物情况,分析影响消化内镜消毒质量的因素。结果103条钳子管道中,70条(67.96%)有组织胶残留;无残留组消化内镜消毒合格率及细菌学检查合格率均高于残留组,差异有统计学意义(P<0.05);合格组消毒人员数为4人者占比、消毒用水质量合格者占比高于不良组,差异有统计学意义(P<0.05)。结论钳子管道组织胶残留率越高,细菌检出率越高,消化内镜消毒质量越低。消毒用水质量及消毒人员数可影响消化内镜消毒质量。

Objective To explore the effect of residual tissue glue in forceps channels on the disinfection quality of digestive endoscopes.Methods A total of 103 forceps channels of digestive endoscopes in the Digestive Endoscopy Center of the hospital from March 2022 to June 2023 were randomly selected,and the residual situation of tissue glue in the forceps channels of the endoscopes was observed after cleaning and disinfection.The endoscopes were divided into residual group and non-residual group based on the residual situation of tissue glue in the forceps channels,the disinfection quality and microbial conditions of digestive endoscopes in both groups were detected,and the factors affecting the disinfection quality of digestive endoscopes were analyzed.Results Among the 103 forceps channels,70 channels(67.96%)had residual tissue glue;the disinfection qualification rate and bacteriological qualification rate of the non-residual group were significantly higher than those of the residual group(P<0.05).There were four personnel carrying out disinfection,and the proportion of qualified disinfection water quality was higher than that of poor group(P<0.05).Conclusion The higher the residual rate of tissue glue in forceps channels and the bacterial detection rate are,and the lower the disinfection quality of digestive endoscopes is.The quality of disinfection water and the number of disinfection personnel can affect the disinfection quality of digestive endoscopes.
