Methods:during the year 2003 to 2006,3298 patients with vaginal delivery received 2 kinds of skin preparations.retrospective study was conducted to investigate the effect of skin preparation methods on the healing of mediolateral episiotomy.rerults:there was no different effect on the wound healing of mediolateral episiotomy between the 2 kinds of skin preparation.conclusions:non-shaving method has no adverse effect on the sterilization of operation field in vaginal delivery.moreover it can save the time of nuring,lower the costs,ease the uncomfortable feeling .therefore,we consider the non-shaving method has advantage over the shaving one.the former is simple and effective which is an ideal way to simplify nursery procedure and spare nursery resource.

收集我院2003年至2006年间共3298例阴道分娩的产妇采用两种不同的备皮方法，观察两种备皮方法对会阴侧切伤口的影响进行回顾性对比分析。结果：两种备皮方法对会阴侧切伤口的愈合影响无明显差异。结论：不剃毛的会阴备皮方法对阴道分娩的手术野消毒无不良影响，并且能够节省护理操作时间、降低产妇费用、减轻产妇不适，所以不剃毛的备皮方法优于剃毛的备皮方法，不剃毛的备皮方式简单而有效，是简化护理工作程序及节省护理人力资源的理想办法。
