摘　　要：目的了解使用皂液洗手后流动水冲洗时间对洗手效果的影响,并确定最佳冲水时间。方法对临床正在从事工作的60名医务人员随机分为两组,洗手前分别采集标本,采集后用皂液按六步洗手法洗手,揉搓15 s后用流动水按六步洗手法冲洗手上肥皂沫,第1组冲洗20 s,第2组冲洗30 s,两组待手干后分别再次采集标本;标本采集后均置37℃温箱培养48 h后进行细菌学计数。结果洗手后冲洗20、30 s细菌菌落数均较洗手前下降(P<0.05),冲洗30 s较冲洗20 s手细菌菌落数减少明显(P<0.05);冲洗30 s合格率为93.33%,高于冲洗20 s的53.33%(2χ=12.273,P<0.05)。结论冲洗时间对洗手效果有影响,冲洗30 s效果优于冲洗20 s效果。OBJECTIVE To know the influence of flushing time after washing hand with soap fluid for hand washing effect,and determine the optimal flushing time.METHODS The clinical staff 60 were engaged in work were randomly divided into two groups and collected specimen respectively before washing hands,Then flushed the foam after washing hands with soap fluid and rubbing 15 seconds according to the method of six-step.Group 1： flushed for 20 seconds,group 2： flushed for 30 seconds.The groups were respectively collected specimen again after waiting for dry hands.The bacterium colony after cultivating for 48 hours in 37 ℃ incubator was counted.RESULTS After washing and flushing for 20 seconds or 30 seconds,the number of bacterial colony decreased,and the effect and qualified rate of flushing for 30 seconds was better than flushing for 20 seconds.CONCLUSION Flushing time for hand washing effect has influence,the effect of flushing for 30 seconds is better than flushing for 20 seconds.
