摘　　要：目的探讨季铵盐复方消毒液对医院物体的消毒效果,为临床选择高效、安全的消毒液提供依据。方法本院于2017年1月~2017年5月期间,分别使用季铵盐消毒液和次氯酸钠消毒液对采血台、血液透析机以及ICU床栏为进行表面消毒处理,采用琼脂平板法采集各消毒区域表面细菌进行培养并计数。比较两种消毒液消毒前、消毒后5 min以及消毒后4 h各区域表面菌落数及合格率情况。结果两种消毒液消毒后采血台、血液透析机及ICU床栏菌落数均显著降低(P<0.05),两种消毒液消毒后5 min菌落数比较差异无统计学意义,季铵盐消毒液消毒后4h采血台、血液透析机及ICU床栏菌落数均显著低于次氯酸钠消毒液(P<0.05)。两种消毒液对采血台、血液透析机以及ICU床栏较消毒后合格率均达到100%,消毒后4 h合格率均有所降低(93.33%、90.00%、74.19%;90.00%、96.67%、83.33%),但均显著高于消毒前(P<0.05),两种消毒液之间消毒前、消毒后5 min及消毒后4 h合格率比较差异无统计学意义。结论季铵盐消毒液对采血台、血液透析机及ICU床栏等医院物体消毒效果满意,相较于传统的含氯消毒液,季铵盐消毒液具有腐蚀性小、灭菌效率更高且维持时间更长等特点,在医院物体的消毒中具有重要的应用价值,值得推广应用。Objective To investigate the disinfection effect of quaternary ammonium compound disinfectant on hospital objects, and to provide the basis for clinical selection of efficient and safe disinfectant. Methods In our hospital in January 2017 to May 2017, respectively using quaternary ammonium salt disinfectant and sodium hypochlorite disinfectant on blood, blood dialysis machine and ICU bed column for surface disinfection,disinfection of bacteria on the surface of each region collected were cultured and counted by agar plate method. The surface bacteria count and qualified rate of two kinds of disinfectant before disinfection, after disinfection 5 min and after disinfection 4 h were compared. Results Two kinds of disinfectant after blood collection, blood dialysis machine and ICU bedrails colonies were significantly decreased(P<0.05), two 5 min after disinfection of colonies with no significant difference, 4 h blood stage of hemodialysis, quaternary ammonium disinfectant disinfection machine and ICU bedrails colonies were significant less than sodium hypochlorite(P<0.05). Two kinds of disinfection liquid on blood, blood dialysis machine and a ICU bed column after disinfection qualified rate reached 100%, 4 h after disinfection qualified rate were decreased(93.33%, 90.00%, 74.19%; 90.00%,96.67%, 83.33%), but were significantly higher than those before disinfection(P<0.05), between the two kinds of disinfectant before and after disinfection of 5 min and 4 h after disinfection qualified rate is not significant the difference. Conclusion Disinfection solution of quaternary ammonium salt of Taiwan, disinfection effect of object blood dialysis machine and ICU bed hospital satisfaction, compared with the traditional liquid chlorine disinfection, disinfection solution of quaternary ammonium salt has the characteristics of corrosion and the sterilization efficiency is higher and longer duration, which has important application value in disinfection of hospital objects, worth application.
