摘　　要：目的 比较不同pH值的强碱性电解水对手术器械的清洁效果及腐蚀性能。方法 对器械进行模拟污染,比较强碱性电解水浸泡、浸泡+超声波等方式对特定手术器械的清洗效果,比较不同pH值强碱性电解水对不同类型手术器械的清洗效果,称重法比较强碱性电解水对马氏体不锈钢、奥氏体不锈钢等常用金属的腐蚀性。结果 pH值越高,强碱性电解水清洁能力越强,pH值达到13.0时,常温下浸泡即可达到45℃多酶清洗剂与超声波协同处理的效果;该处理可使有齿有关节类器械、有齿无关节类器械、无齿有关节类器械和管腔类器械上ATP的去除率分别达到98.81%、99.35%、98.30%和99.22%,与多酶组清洁能力差异无统计学意义(P>0.05);强碱性电解水对马氏体不锈钢、奥氏体不锈钢腐蚀速率均<0.010 0 mm/a。结论 pH值为13.0的强碱性电解水对手术器械具有良好清洗效果,对器械的腐蚀作用小。Objective To compare the cleaning effectiveness and corrosion properties of strong alkaline electrolyzed water at different pH values on surgical instruments.Methods The cleaning effect of strong alkaline electrolyzed water immersion,immersion+ultrasound on specific surgical instruments was compared,and the cleaning effect of strong alkaline electrolyzed water with different pH values on different types of surgical instruments was compared.The corrosive properties of alkaline electrolyzed water on martensitic stainless steel,austenitic stainless steel and other commonly used metals were compared by weighing method.Results The higher the pH value,the stronger the cleaning ability of the strong alkaline electrolyzed water was.When the pH value reached 13.0,the effect by immersion at room temperature could reach that of multi-enzyme cleaning agent and ultrasonic co-treatment at 45℃.The removal of ATP from toothed articulated devices,toothless articular devices,toothless articulated devices and lumen devices reached 98.81%,99.35%,98.30%and 99.22%respectively.There was no significant difference in cleaning ability with the multi-enzyme group(P>0.05).The corrosion rate of strong alkaline electrolyzed water on martensitic stainless steel and austenitic stainless steel were lower than 0.0100 mm/a.Conclusion Strong alkaline electrolyzed water with pH 13.0 has a good cleaning effect on surgical instruments and has little corrosive effect on instruments.
