对静脉留置针肝素帽三种不同消毒方法的效果比较

Disinfection effect on heparin cap of intravenous detention

目的探讨三种消毒剂对肝素帽的消毒效果。方法选择静脉留置针患者90例,根据消毒方法不同,随机分为安尔碘组、5%碘伏组、2%碘酊+75%酒精组,每组各30例。在静脉留置针留置期间,三组每隔24小时各消毒肝素帽3次,待干后采样,送检,进行细菌培养,通过细菌培养观察肝素帽的消毒效果。结果观察至第5天时,安尔碘组和5%碘伏组均无细菌检出,两组比较,差异无统计学意义(P>0.05);2%碘酊+75%酒精组在留置第3天时即有细菌检出,随着留置时间延长,阳性率有明显增高趋势,与安尔碘组、5%碘伏组比较,差异有统计学意义(P<0.05)。结论静脉留置针留置期间,安尔碘对肝素帽消毒效果肯定,且速干,无需脱碘,长效杀菌作用肯定,便于临床操作而值得推广。

Objective To compare disinfection effect on heparin cap of intravenous detention with different methods.Methods 90 patients were divided into 3 groups with 75% alcohol,2% iodine and both 75% alcohol and 2% iodine,respectively.The disinfection effect was evaluated with germiculture.Results The disinfection effect of iodione on heparin cap was better than the other two methods.Conclusion It is effective to sterilize heparin cap with iodine.
