【摘要】目的 探討使用不同預(yù)處理方法對(duì)于醫(yī)療器械進(jìn)行清洗效果的影響。方法 選取2013年9月至2015年9月在我科進(jìn)行消毒的醫(yī)療器械600件,隨機(jī)分為3組,每組各200件。預(yù)處理方法為A組采用流動(dòng)水沖洗后放入清水中浸泡10min;B組直接用新鮮配制的多酶清洗液浸泡10min;C組用流動(dòng)水沖洗后放入新鮮配制的多酶清洗液浸泡10min,比較三組目測、鏡檢以及隱血試驗(yàn)檢測法的合格率。結(jié)果 A組、B組、C組3組目測法合格率分別為93.50%、95.50%、99.00%;8倍放大鏡檢測法3組合格率分別為92.00%、94.50%、98.50%;隱血試驗(yàn)法3組合格率分別為90.50%、92.50%、97.50%。C組合格率與其余兩組比較差異均有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論 回收的醫(yī)療器械流動(dòng)水沖洗后放入新鮮配制的多酶清洗液浸泡進(jìn)行預(yù)處理,對(duì)于提高器械清洗效果具有顯著意義。

Abstract :Objective To investigate the effect of different pretreatment methods on the cleaning effect of medical instruments. Method 600 medical instruments were selected in our departmentfrom September 2012 to September 2014, Randomly divided into 3 groups, each group has 200. The pretreatment method for the A group by using the flow of water to wash the water into the water after soaking 10min; In the B group, the 10min was prepared by using the fresh prepared multi enzyme cleaning solution; The C group was treated with the flowing water and the fresh prepared multi enzyme cleaning solution was soaked by 10min, The qualified rate of three cleaning methods by visual examination and occult blood test. Result A group, B group, C group 3 visual inspection pass rate was 93.50%, 95.50%, 99.00%; The pass rate of 8 times the magnifying glass detection method was 92%, 94.50%, 98.50%; Occult blood test pass rates were 90.50%, 92.50%, 97.50%. The difference between the C group and the other two groups was statistically significant (P<0.05). Conclusion The recovery of the medical device and the flow of water in the fresh preparation of the multi enzyme cleaning liquid immersion, for improving the cleaning effect of the device is significant.
Keywords :multi enzyme cleaning solution; occult blood test; cleaning effect

醫(yī)療器械的清洗及滅菌效果與醫(yī)院感染的發(fā)生率有密切關(guān)系[1],醫(yī)療器械使用后進(jìn)行徹底的清潔處理,去除附著在上面的血液、粘液、體液等有機(jī)物是預(yù)防和控制醫(yī)院感染,保證醫(yī)療安全的重要環(huán)節(jié)。無論采用手工清洗或者機(jī)械清洗,清洗前的預(yù)處理是必不可少的過程,主要包括對(duì)器械進(jìn)行保濕處理、清潔度的檢查、器械分類、特殊污染器械的消毒處理等[2-3]。對(duì)于一些結(jié)構(gòu)復(fù)雜的器械應(yīng)充分拆開,器械隱蔽處的殘留物可在微生物表面形成一層保護(hù)薄膜,影響消毒滅菌的效果[4]。此次研究討論采用不同預(yù)處理方法對(duì)于手術(shù)器械清洗效果的影響,為提高手術(shù)器械清洗質(zhì)量提供依據(jù),現(xiàn)總結(jié)如下。
1 資料與方法
1.1 一般資料2013年9月至2015年9月在我科進(jìn)行消毒的醫(yī)療器械600件,其中包括齒類器械、管腔類器械、擴(kuò)陰器、血管鉗、組織鉗、持針鉗,每類器械100件,共計(jì)600件,隨機(jī)分為三組,每組各200件。
1.2 清洗方法 A組采用流動(dòng)水沖洗后放入清水中浸泡10min;B組直接用新鮮配制的多酶清洗液浸泡10min;C組用流動(dòng)水沖洗后放入新鮮配制的多酶清洗液浸泡10min。預(yù)處理完成后,均放到自動(dòng)清洗消毒器中,清洗消毒干燥完成后,取出器械進(jìn)行檢驗(yàn)。
1.3 檢測標(biāo)準(zhǔn)[5] 目測法:器械表面、卡槽、管腔處均光潔,無殘留血跡、無水印、無銹跡,任何一項(xiàng)不達(dá)標(biāo)均視為不合格。鏡檢法:采用帶光源的8倍放大鏡仔細(xì)觀察,標(biāo)準(zhǔn)與目測法相同。隱血試驗(yàn)檢測法:采用隱血試劑專用測試紙進(jìn)行檢測,取試紙1條,分別滴加A劑,完全滲透后再滴入B劑,A劑和B劑比例為1:1,在待檢測的手術(shù)器械表面及齒槽處反復(fù)擦拭,1min內(nèi)試紙不變色即為陰性,出現(xiàn)不同程度紫色為陽性,視為不合格。
