摘　　要：目的探究清凉油外敷对延长Sprague-Dawley(SD)大鼠尾静脉留置针固定时间的作用。方法将课题实验中的100只SD大鼠随机分为两组,即对照组和改良组,两组大鼠均采用相同的方法进行单侧尾静脉穿刺置管。对照组采用医用胶布传统方法固定即可;改良组在对照组基础上,将清凉油均匀的涂抹于医用胶布和留置针表面,分别观察记录两组大鼠尾静脉留置针的留置时间。结果对照组SD大鼠尾静脉留置针留置时间为(7.05±6.34)h,改良组SD大鼠尾静脉留置针的留置时间为(90.36±27.42)h,两组留置时间比较,差异具有统计学意义(P<0.01)。结论改良后的固定方法操作更加简便快捷,安全可靠,能够有效的延长尾静脉留置针的留置时间,为动物实验静脉留置针的使用提供了新方法。Objective To explore a practical fixation method of the unilateral indwelling needle inserted in the Sprague-Dawley rat tail vein covered with essential balm and record the indwelling time. Method 100 male SD rats were divided into two groups randomly： the control group and the improved group. All rats used the same disposable indwelling needle puncture and cannulation. Rats in both groups received the traditional fixation with medical rubberized fabric. In adition to the traditional fixation,the improved group covered with essential balm.The indwelling time was recorded. Result The indwelling time was（ 7. 05 ± 6. 34） h and（ 90. 36 ± 27. 42） h in the control and experimental groups,respectively（ t =- 20. 929,P〈0. 01）. Conclusion Our new method is more safe and convenient than the traditional method prolonging the indwelling time effectively and providing a useful fixation method of indwelling needel inserted in the rat tail vein.
