压力蒸汽灭菌覆膜化学指示卡的临床应用效果探究

Study on the Clinical Application Effect of Pressure Steam Sterilization Coated Chemical Indicator Card

目的比较覆膜化学指示卡与普通化学指示卡在临床使用中的效果,为医院消毒供应室灭菌监测质量的提升提供参考。方法选取在2018年1月至2018年3月期间的每锅次压力蒸汽灭菌过程中,将待灭菌物品按照敷料包、器械包和纸塑袋包装分为3组。各组分别放置普通型132℃压力蒸汽灭菌化学指示卡、Ⅰ型覆膜132℃压力蒸汽灭菌化学指示卡、Ⅱ型覆膜132℃压力蒸汽灭菌化学指示卡各一条,另外再放置一支自含式快速生物指示剂。同时每锅次使用化学PCD和生物PCD对灭菌器的综合灭菌性能进行监测。并记录每次灭菌的物理监测结果。结果在每锅次物理监测、化学PCD监测和生物PCD监测均合格及每个灭菌包的生物监测均合格的情况下,Ⅱ型覆膜指示卡变色在3组中的合格率均为100%;Ⅰ型覆膜指示卡平均变色合格率分别为100%,98.32%和97.82%;普通型化学指示卡的平均变色合格率分别为99.67%,89.83%和94.81%。结论在医院临床使用覆膜型的化学指示卡有更准确的监测率,指示效果更可靠,值得在临床压力蒸汽灭菌中推广。

Objective To compare the effect of chemical indicator card and general chemical indicator card in clinical use,and to provide references for the improvement of sterilization monitoring quality in hospital sterilization supply room.Methods In the process of steam sterilization for every pot of pressure during the period from January 2018 to March 2018,the sterilization items of the dressing package,instrument package and paper plastic bag were divided into three groups on average.Each group was separately placed an ordinary chemical indicator card coated 132℃pressure steam sterilization bags monitoring,a typeⅠcoated 132℃pressure steam sterilization bags monitoring chemical indicator card and a typeⅡcoated 132℃pressure steam sterilization bags monitoring chemical indicator card.In addition,a self-contained fast biological indicator was placed.At the same time,chemical PCD and biological PCD were used to monitor the comprehensive sterilization performance of sterilizer.Physical monitoring results of each sterilization were recorded.Results Under the condition of each pot physical monitoring,chemical PCD monitoring,biological PCD monitoring and every pot time batch monitoring were all qualified,the pass rate of typeⅡcoated sheet discoloration was 100%in the three groups,while the average color coated sheet qualified rate of TypeⅠwas 100%,98.32%and 97.82%respectively,and the average color change rate of common chemical indicator CARDS was 99.67%,89.83%and 94.81%,respectively.Conclusion The clinical use of laminated chemical indicator card in hospital has more accurate monitoring rate and more reliable indicator.It is worth to be popularized in clinical pressure steam sterilization.
