爱护佳洗手液在外科手消毒中应用前景的研究

Research on prospects of Aihujia hand disinfectant applied in surgical hand disinfection

目的比较爱护佳手消毒液与传统的聚维酮碘在外科术前洗手消毒的效果。方法受试医务人员随机分为两组,即聚维酮碘组(对照组)和爱护佳组(观察组),比较两组的手感染率差异、两组洗手时间的差异,在不同时间点(消毒后即刻、30、60、120min)的手部检出细菌数量的差异;另选择Ⅰ、Ⅱ、Ⅲ三类不同切口的患者,分别使用两种消毒剂消毒,比较它们对三类切口感染率的差异。结果聚维酮碘组和爱护佳组的手部带菌率差异无统计学意义;两组间洗手时间比较,差异有统计学意义(P<0.01),爱护佳组时间较短;两组间消毒后<120min手部细菌检出量差异无统计学意义;Ⅰ、Ⅱ、Ⅲ3类切口患者分别使用两种消毒剂消毒后,切口感染率的差异无统计学意义。结论爱护佳手消液是一种新型的良好的外科洗手消毒液。

OBJECTIVE To compare the effects of Aihujia hand disinfectant with the traditional iodophor disinfectant before surgery in surgical hand disinfection.METHODS Subjects of medical personnel were randomly divided into two groups,i,e.povidone iodine（control group） and Aihujia group.The infection rates of hand,time of hand washing and the amount of bacteria detected at different time points（immediately,30,60 and 120 min after disinfection） were compared.Patients with classes Ⅰ,Ⅱand Ⅲ incisions were disinfected by using two methods,and infection rates of the three incision classes were compared.RESULTS Hand infection rates between iodophor group and Aihujia group had no significant difference.Time of hand washing between the two groups was statistically different（P=0.002）.Aihujia group had a shorter time.Difference in the amount of bacteria in the hand detected after disinfection in 120/min between the two groups was not statistically significant.Patients with classesⅠ,Ⅱand Ⅲincisions were disinfected by using the two methods respectively.Their infection rates of the wound were not significantly different.CONCLUSION Aihujia is a new and favorable hand disinfectant in surgical hand disinfection.
