不同清洁洗手方法对外科手消毒效果的影响

Effect of different methods of hand washing on surgical hand antisepsis

目的比较不同的清洁洗手方法对外科手消毒效果的影响。方法使用同种手清洁剂和外科手消毒剂,分别采取揉搓清洁洗手(A组)、刷洗清洁洗手(B组)和不进行清洁洗手(C组)3种方法后按同样的方法进行外科手消毒,比较其即刻消毒效果和对手部皮肤的影响。结果 C组外科手消毒后手部菌落数(0.27±0.45)CFU/cm2及手部带菌阳性率(46.7%)明显高于A组和B组,差异有统计学意义(P<0.01),A组和B组之间比较,差异无统计学意义,均有较好的即刻消毒效果,但刷洗法对皮肤损伤较大。结论外科手消毒前推荐使用揉搓清洁洗手方法。

OBJECTIVE To compare the influence on the effect of surgical hand antisepsis by different methods hand washing. METHODS With the same liquid skin cleaner and surgical hand disinfectant, prior to surgical hand antisepsis, three methods were selected to compare their immediate antimicrobial efficacies and effct on skin conditions, including hand rub （group A）, hand scrub （group B） and no pre wash （group C）. RESULTS In the group C,the colonies（0. 27±0. 45 CFU/cm2）and the positive rate（46. 7%）after surgical hand antisepsis were higher than that of group A and B, there was no significant difference between the group A and B. Hand rub resulted in a smaller skin damage than hand scrub. CONCLUSION Hand rub is the recommended method for prior hand washing to surgical hand antisepsis.
