外科术前免刷式洗手消毒效果监测及评价

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 125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 40份标本中,无菌检验率为 95 %,采用含中和剂取样的 40份标本中,无菌检验率为 90 %,有菌检出菌落数均<5 CFU/ cm2;乙组洗手消毒后,均采用含中和剂采样液采样 45份,无菌检验率为 71. 11 %,有菌检出率为 28. 88 %;检出菌落数≤5 CFU/cm2,占总数的 17. 77 %;检出菌落数≥15 CFU/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;而清洗质量是消毒灭菌效果的先决条件和保证.

Effect of Two Surgical Hand Sterilizing Methods

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.
