氯己定醇皮肤消毒液应用于儿童浅静脉留置针的效果评价

Effect of chlorhexidine on disinfection of peripheral venous indwelling needles of pediatric patients

目的探讨2%葡萄糖酸氯己定醇皮肤消毒剂对儿童浅静脉留置针消毒效果。方法选择2012年8月-2013年1月在儿科行浅静脉留置针穿刺的患儿300例,随机分为观察组和对照组各150例;观察组使用2%葡萄糖酸氯己定醇进行皮肤消毒,对照组使用安尔碘进行皮肤消毒,分别在消毒前,第1、2次消毒后和消毒72h后对两组进行细菌采样,比较消毒效果。结果使用2%葡萄糖酸氯己定醇在第1次消毒和消毒72h后的患儿皮肤菌落数低(P<0.05),且2%葡萄糖酸氯己定醇的消毒待干时间(16.81±1.47)h更短,差异有统计学意义(P<0.05)。结论 2%葡萄糖酸氯己定醇在儿童浅静脉留置针的消毒效果确切,且可视度高、待干时间短,为护理人员的临床工作提供了便利,较传统的安尔碘消毒液更具优越性,值得临床推广和应用。

OBJECTIVE To evaluate the effect of 2% chlorhexidine skin disinfectant on the disinfection of the peripheral venous indwelling needles of the pediatric patients. METHODS A total of 300 pediatric patients who had indications of using peripheral venous indwelling needle from Aug 2012 to Jan 2013 were enrolled in the study and were randomly and equally divided into the experimental group and the control group. The patients in the experi- mental group were sterilized by 2% chlorhexidine skin disinfectant, while the patients in the control group were sterilized by anerdian before the indwelling of the peripheral needle. The bacterial samples were respectively obtained before the disinfection, the first time and the second time after the disinfection, and 72 hours after the disinfection, then the disinfection effects were compared. RESULTS Compared with anerdian, the bacterial colony counts were significantly less in the 2% chlorhexidine skin disinfectant group at first time or 72 hours after the disinfection （P〈0.05）, and the 2% chlorhexidine needed less time to dry （16.81±1.47） h, the difference was statistically significant （P〈0.05）. CONCLUSION The study concludes that the 2% chlorhexidine skin disinfect- ant shows accurate disinfection effect, with the visibility high and the time to dry short, which facilitates the clini- cal disinfection and is superior to the traditional anerdian, thus it is worthy to be promoted in the hospital.
