妇科窥阴器不同清洗方法的效果比较

Different Cleaning Methods for Gynecological Bivalve Speculum:A Comparison of Results

目的比较5种不同清洗方法对窥阴器残留血迹等有机物的清洗效果。方法取妇科小手术使用过的明显污染血迹的窥阴器400件,分成手工清洗法、超声波清洗法、全自动清洗法、人工清洗+超声波清洗法、人工清洗+全自动清洗法,并进行目测法、放大镜检测法和潜血试验检测。结果5组窥阴器目测检测阳性率依次为5.00%、3.75%、2.50%、0、0,放大镜检测阳性率为7.50%、5.00%、3.75%、1.25%、1.25%,潜血试验检测阳性率为15.00%、12.50%、8.75%、4.00%、2.00%。结论5种清洗方法的效果差异有统计学意义(P<0.05),人工清洗+超声波清洗法和人工清洗+全自动清洗法的清洗效果好于其他方法。

OBJECTIVE To compare the effects of cleaning the bloodstain and other organic matter left on the bivalve speculum by 5 different cleaning methods. METHODS The following methods were adopted for 400 bivalve speculums with bloodstain left from gynecological operations., manual cleaning method, ultrasonic cleaning method, fully automatic cleaning method, artificial cleaning plus ultrasonic cleaning method, artificial cleaning plus fully automatic cleaning method, and the effects were detected by visual observation method, magnifier detection method and occult blood test method. RESULTS The positive rate of visual observation on 5 groups of bivalve speculums was 5.00%, 3.75%, 2.50%, 0 and 0, respectively, the positive rate of magnifier detection was 7.50%, 5.00%, 3.75%, 1.25% and 1.25%, respectively, and the positive rate of occult blood test was 15.00%, 12.50%, 8.75%, 4% and 2%, respectively. CONCLUSIONS There are significant differences among 5 cleaning methods （P〈 0. 05）, the cleaning effects of artificial cleaning plus ultrasonic cleaning method and artificial cleaning plus fully automatic cleaning method are better than other methods.
