外科术前免刷式洗手消毒效果监测及评价

Effect of Two Surgical Hand Sterilizing Methods

目的 对外科手术人员刷手后消毒和洗手后消毒效果进行比较。方法 将刷手消毒和洗手消毒分为两组 ,均采用 0 5 %碘伏消毒液进行皮肤消毒 ,并采用无菌盐水和加中和剂两种采样方式 ,随机对参加手术的 85名医护人员 ,分别采样 12 5份 ,进行细菌学检测对比 ;统计学处理 :采用 χ2 检验和校正 χ2 检验方法。结果 甲组刷手消毒后 ,使用无菌盐水进行采样的 4 0份标本中 ,无菌检验率为 95 % ,采用含中和剂取样的 4 0份标本中 ,无菌检验率为 90 % ,有菌检出菌落数均 <5CFU/cm2 ;乙组洗手消毒后 ,均采用含中和剂采样液采样 4 5份 ,无菌检验率为 71.11% ,有菌检出率为 2 8.88% ;检出菌落数≤ 5CFU/cm2 ,占总数的 17.77% ;检出菌落数≥ 15CFU/cm2 ,占总数的 11.11%。结论 实验结果表明 ,甲组方法进行消毒效果比乙组方法为好 ;进一步验明采取刷手比洗手方法对细菌清除率要高 ;

OBJECTIVE To study the effect of two surgical hand sterilizing methods. METHODS Eighty five surgeons and nurses were divided randomly into two groups. In group A, hands were scrubed using 0 5% iodophor. In group B, hands were washed using 0 5% iodophor. A total of 125 samples were collected by sterile saline or neutralizer and cultured. RESULTS Forty samples were collected by saline sterile in group A, the aseptic rate was 95%. Forty samples were collected by neutralizer in group A, the aseptic rate was 90%, all colonies were less than 5 CFU/cm 2. Forty five samples were collected all by neutralizer in group B, the aseptic rate was 71 11%, 17 77% of the samples was no more than 5 CFU/cm 2, 11 11% more than 15 CFU/cm 2. CONCLUSIONS The sterile effect of hands scrubing is better than hands washing.
