摘　　要：目的比较不同清洗方法对腹腔镜清洗效果的影响,为进一步规范腹腔镜清洗提供依据。方法选择腹腔镜手术分离止血钳320件,分为8种方法清洗,每组40件;采用隐血试验检测清洗效果。结果术中加压、术后多酶、术后超声均能降低隐血试验阳性率(压力OR=0.326,多酶OR=0.430,超声OR=0.506,P=0.001);三者间清洗效果相当,Breslow-Day检验,2χ值=3.104,P=0.376>0.05);分离钳部位(轴关节、管腔内)在不同清洗方法中清洗效果差异有统计学意义(P<0.05)。结论对腹腔镜采用多酶、超声清洗与术中加压冲洗是必要的;提高清洗效果,应重视管腔与轴关节的清洗。OBJECTIVE To compare effects of different cleaning methods on washing laparoscopy efficacy,in order to provide the basis for further regulating the cleaning standards of laparoscopes.METHODS Three hundred and twenty gynecological laparoscopic forceps were divided into eight cleaning groups,each group had 40 forceps.Occult blood test was used to evaluate the effect of washing.RESULTS High-pressure flushing during operation,multi-enzyme abluent and ultrasonic wave cleaning could reduce the positive rate of occult blood test（high-pressure method OR=0.326,multi-enzyme abluent OR=0.430,ultrasound wave OR=0.506,P=0.001）;cleaning effects were the same among the three washing methods,（Breslow-Day test,χ2=3.104,P=0.3760.05）.Cleaning efficacies at parts of the instruments（shaft joints,lumen） varied with different cleaning methods,with statistically significant differences（P 0.05）.CONCLUSIONS It is necessary to adopt high-pressure flushing,multi-enzyme abluent or ultrasonic wave in the cleaning of laparoscopic instruments;it should pay attention to washing the lumen and the axis joints,which can improve the cleaning effectiveness.
