神经外科监护病房高频接触物体表面消毒频次的研究
|
摘要
目的通过对神经外科监护病房(ICU)高频接触物体表面消毒现状的调查,探讨最佳消毒频次。方法选取吉林大学第一医院神经外科ICU内的床栏、微量泵、监护仪按钮、洗手液按压开关、鼠标、病历的物体表面共6项为研究对象。分别于消毒后2、4、6、8 h进行采样,培养48 h后读取菌落数。比较不同消毒后时间点的菌落数。结果床栏和监护仪按钮消毒后不同时间点采样菌落数比较,差异无统计学意义(均P>0.05),平均菌落数均<5 CFU/cm~2。微量泵、洗手液按压开关、鼠标、病历消毒后不同时间点采样菌落数比较,差异具有统计学意义(均P<0.05);该四类物体表面消毒后8 h的菌落数均高于消毒后6 h(均P<0.05)。结论 ICU内不同高频接触物体表面的污染情况存在一定差异,应根据高频接触物体表面的实际情况制定最佳的消毒频次。
Objective To investigate the current situation of disinfection of high-touched object surface in neurosurgical intensive care unit(ICU),and explore the optimal frequency of disinfection.Methods Six kinds of hightouched objects,including bed bar,micro-pump,monitor button,hand sanitizer button,mouse and medical history,were selected as the research objects in neurosurgical ICU of The First Hospital of Jilin University.Specimens were taken at 2,4,6 and 8 hours after disinfection,and colony counts were calculated after 48 hours of culture.The number of colonies at different time points after disinfection were compared.Results There was no significant difference in the numbers of colonies on bed bar and monitor button at different sampling time points after disinfection(all P>0.05),the average number of colonies was<5 CFU/cm~2.There were significant differences in the numbers of colonies on micro-pump,hand sanitizer button,mouse and medical history at different sampling time points after disinfection(all P<0.05);the number of colonies at 8 hours after disinfection were all higher than that at 6 hours after disinfection(all P<0.05).Conclusion There are some differences in surface contamination of different high-touched object surface in ICU,the best disinfection frequency should be determined according to the actual condition of high-touched object surface.
