手术前备皮方法-剃毛与不剃毛的实验研究与临床意义

The research of skin preservation before operation-razored or unrazored

手术前清洁皮肤剃除手术野的毛发,被列为外科手术前常规,其利弊如何,已有学者提出异议,笔者做了一组临床实验证明:剃毛备皮组24h后皮肤表面细菌存留数明显高于不剃毛备皮组。剃毛备皮组每平方厘米细菌菌落数在8个以上者有17例,不剃毛备皮组仅4例。两组备皮后24h表面单位面积菌落数有显著意义(P<0.01),为此,剃毛备皮法易增加术后感染。

It's considered as a routine to clean and razor the hair of the incision region before operation.The author's conclusions:24 hours after skin preparation, the razored group will have much more bacteria on skin than unrazored group. There are 17 cases which have more than 8 colonies per square centimeter with only 4 cases in unrazored one. They all have statis-ticall significance. So the preparation method with skin razored will enhance the possibility of infection.
