摘要
目的探讨安全、有效的夜间手术器械清洗流程和方法,提高夜间手术器械的清洗质量。方法将夜间使用后的手术器械1680件(咬合类器械1200件、管腔类器械480件),随机分为A、B、C、D组,采用4种不同的清洗方法;A组:立即清洗法;B组:干式保存法;C组:刷洗保存法;D组:酶液保存法,比较各组目测、5倍放大镜、特殊棉签检测、残留血检测、菌落数及内毒素检测合格率。结果 A、B、C、D组合格率目测为78.3%、86.9%、94.5%、96.4%;5倍放大镜为71.9%、81.9%、92.6%、93.8%;特殊棉签检测为59.2%、74.2%、90.8%、93.3%;残留血检测为64.2%、85.8%、96.7%、98.3%;菌落数为46.7%、93.3%、100.0%、100.0%;内毒素为43.3%、93.3%、100.0%、100.0%。经统计学检验,4组比较差异有统计学意义(P<0.05)。结论使用后的夜间手术器械采用刷洗保存法和酶液保存法,均能明显提高器械的清洗质量及残留血检测合格率,但酶液保存法,具有安全性,可操作性强。
OBJECTIVE To explore the safety and effective process or methods for cleaning surgical instruments at night,and also to improve the cleaning quality of surgical instruments at night.METHODS A total of 1680 pieces surgical instruments（occlusal class device 1200,the lumen type device 480） were divided into A,B,C,D groups randomly,using four different cleaning methods to clean them.Four cleaning methods were A group（immediate cleaning method）;B group（dry stored）;C group（scrub save）;D group（save the enzyme solution）,then six standards,such as visual,five times magnifying glass,special swab testing,residue testing of blood,colony count and endotoxin detection to were used to test the pass rate of these four cleaning methods.RESULTS The pass rates of A,B,C,D group： in visual were 78.3%,86.9%,94.5% and 96.4%;five times magnifying glass were 71.9%,81.9%,92.6% and 93.8%;white gauze were 59.2%,74.2%,90.8% and 93.3%;residual blood test were 64.2%,85.5%,96.7% and 98.3%;colonies count was 46.7%,93.3%,100.0%,100.0% and endotoxin detection was 43.3%,93.3%,100.0% and 100.0%.With the statistical test,the differences among them had statistically significant（P0.05）.CONCLUSION The surgical instruments after cleaning by method C and D have higher cleaning quality than other two methods,also method D is safer and more workable.
