摘　　要：目的 :比较不同外科洗手时间和方法对术前消毒效果的影响,探讨术前外科手消毒的最佳方法。方法 :按完全随机的方法把手术医生和器械护士共100人平均分为4组:A组和C组分别揉搓洗手1 min和3 min;B组和D组分别刷洗洗手1 min和3 min,以手细菌培养计数法比较消毒洗手前后手部菌落数、菌落阳性率及不同洗手时间和方法对皮肤的影响。结果 :各组外科消毒洗手前后菌落数及阳性率无明显差异(P>0.05);A、C两组洗手后皮肤外观、完整性、感觉HSA评分较本组洗手前无明显变化(P>0.05);B、D两组洗手后皮肤外观、完整性和感觉HSA评分较本组洗手前明显降低(P<0.05);四组洗手后皮肤湿度HSA评分较本组洗手前均明显增加(P<0.05)。结论 :洗手时间和方法对消毒效果无明显影响,揉搓法对皮肤损伤小,故临床上推荐1 min揉搓外科洗手法。Objective： To compare the effects of different time and methods for surgical hand antisepsis on the efficacy of preoperative disinfection and to investigate its best method. Methods： Total 100 surgeons and nurses were randomly divided into 4 groups based on the method for their surgical hand antisepsis： scrubbing hands for 1 min and 3 min in group A and C, and scrubbing hands with sponge for 1 rain and 3 rain in group B and D, respectively. The number and positive rate of colonies on hands were compared by colony counts before and after hand antisepsis and the effects of different time and methods on the skin were also investigated. Results： There were no significant differences in the number and positive rate of colonies before and after hand antisepsis among 4 groups （P〉0.05）. The appearance, intactness and sensation HAS score of the skin had no significant change after hand antisepsis compared with before antisepsis in group A and C （/：＇〉0.05）, but significantly decreased in group B and D （P〈0.05）. The HAS score of moisture content was significantly increased after hand antisepsis compared with before antisepsis in all of four groups （P〈0.05）. Conclusion： The different time and methods for surgical hand antisepsis have no obvious influence on the disinfection effect, and 1 rain scrubbing method has little lesion to skin. Therefore, it is clinically recommended as a method for surgical hand antisepsis.
