摘要
目的探讨三种手消毒剂对手部消毒效果的影响。方法选取2016年1—12月我市60名医护人员为研究对象,根据医护人员手卫生使用的不同手消毒剂将其分为碘伏组、乙醇组和季铵盐组,每组20名,比较三组手消毒剂对手表面细菌繁殖体的杀灭效果及洗手前后的手带菌情况。结果碘伏组、乙醇组和季铵盐组的KL值分别为1.90、2.07及1.73,三种手消毒剂均有良好的消毒效果,组间比较差异无统计学意义(P>0.05),但对于手带菌量≥50 cfu/cm^2者洗手后,季铵盐组的手带菌量及合格率均优于碘伏组及乙醇组,差异有统计学意义(P<0.05)。结论碘伏、乙醇和季铵盐类消毒剂均具有显著的消毒效果,其中季铵盐类消毒剂在手带菌量≥50 cfu/cm^2者的消毒中更具优势。
Objective To investigate the effect of three kinds of hand disinfectants on the disinfection effect of the opponent part. Methods From Januaruy to December 2016, 60 doctors and nurses in our city were selected as the research subjects. According to the different hand disinfectants used by medical staff, they were divided into iodophor group, ethanol group and quaternary ammonium salt group with 20 in each group. Hand and hand washing before and after the bacteria killing effect compared with three groups of hand disinfectant bacteria propagules of rival surface. Results The KL values of iodophor group, ethanol group and quaternary ammonium salt group were 1.90, 2.07 and 1.73, respectively, and three kinds of hand disinfectants had good disinfection effect. There was no significant difference between the two groups （P 〉 0.05）. But for the amount of bacteria was more than 50 cfu/cm2 with quaternary ammonium group after washing hands, hand the amount of bacteria and the qualifed rate was better than iodine group and ethanol group, the difference was statistically signifcant （P 〈 0.05）. Conclusion Iodine, alcohol and quaternary ammonium salt disinfectant has strong disinfection effect, the quaternary ammonium salt disinfectant in disinfection and bacteria quantity is more than 50 cfu/cm2 had more advantages.
