简介:摘 要:目的 通过全自动清洗机进行手术器械钝化处理降低不锈钢手术器械的生锈率,延长复用不锈钢手术器械使用寿命,节约科室成本。方法 挑选同等锈渍的生锈器械 400件,随机分为两组,每组各200件,实验组将器械放在清洗温度为85℃ ,1:10比例配置的钝化剂中上全自动清洗器进行钝化处理;对照组将器械放在80℃按1:7比例配制的除锈剂中浸泡10 min进行除锈处理,然后取出进行刷洗,比较两组器械除锈合格率。除锈合格的两组器械分别浸泡在0.9%Nacl溶液5 h,模拟器械的再次使用及受污染,比较两组器械返锈率 结果 经过清洗后的器械在经过干燥通过目测与 5 倍镜观察后显示,两组器械除锈合格率差异不大。 两组器械清洗合格后关节处完全打开,依次浸泡在0.9%的Nacl溶液中,经过 5h 的浸泡后观察返锈率,对照组和观察组差异不大,无统计学意义。讨论 全自动清洗机进行手术器械钝化处理方法值得推广。
