骨科术前不同备皮法对皮肤细菌数量的影响研究

Study on the Effects of Different Methods of Preoperative Skin Preparation for Orthopedic Surgery

目的比较三种备皮法对骨科皮肤菌落数影响。方法择期内植入术病人180例分三组,使用不同清洁剂。A组:消毒软皂溶液;B组:消毒软皂溶液和5%PVP-I;C组:75%酒精和5%PVP-I。结果备皮后、手术消毒前组间比较。A组与B组C组之间有统计学意义;C组与B组无统计学意义。结论选择手术室电话通知病房接病人时的备皮时机,用消毒软皂溶液或75%酒精联合5%PVP-I备皮,备皮距手术时间越短,能有效减少皮肤表面细菌数量并保持较长时间的清洁效果,达到骨科备皮的严格要求,值得临床推荐。

Objective To compare the effects of three preoperative skin preparation methods for orthopedic surgery on the skin coenobium count. Method 180 patients who received selective orthopedic implantation surgery during January to December, 2012, were divided into three groups with different detergents. Group A： soft soap solution; Group B： soft soap solution and 5% PVP-I; Group C： 75% ethanol and 5% PVP-I. Results After skin preparation, the comparison between three groups before surgery disinfection was conducted. Statistically significant difference was found between group A and group B as well as group A and group C, but no statistical significant difference was found between group C and group B. Conclusion The time when the notice of transferring patient for surgery by telephone from the surgery room is the best time for skin preparation. Besides, the less duration from the skin preparation with 5% PVP-I combined with soft soap solution or 75% ethanol to the surgery, the less number of bacteria and the longer duration of clean skin surface. The method mentioned above can meet the stringent requirements of orthopedic skin preparation and is worthy of recommendation.
