【摘要】：目的探讨非热力清洗消毒手术器械使用后不同放置时间、预处理方法对清洗效果的影响及不同评价清洗效果的比较。方法对120件使用后普通手术器械分为A、B两组,每组各60件,在清洗前A组给予保湿处理,B组自然放置,根据放置时间分为2、2~6、6h,均采用初洗+酶泡+超声波洗+手洗+酸化水浸泡消毒+纯水冲洗的清洗方法,采用矫正视力法和隐血试纸法检查各组清洗后的效果;采用SPSS15.0软件进行统计分析。结果矫正视力法显示,A、B组放置时间越长,清洗后阳性率越高(χ2=10.909,20.297,P0.05);组间比较,使用后手术器械放置时间2~6、6h,B组阳性率分别为85.0%、60.0%,均高于A组的55.0%、25.0%(P0.05);隐血试纸法在2、2~6、6h检查阳性率分别为15.0%、55.0%、92.5%,均高于矫正视力法的2.5%、30.0%、57.5%(P0.05)。结论手术器械使用后放置时间越长、清洗效果越差,在清洗前给予保湿处理能提高清洗效果,采用隐血试纸法检查清洗效果优于矫正视力法。
[Abstract]:Objective to explore the effect of different placing time and pretreatment method on cleaning effect of non-thermal cleaning and disinfecting surgical instruments and the comparison of different evaluation of cleaning effect. Methods 120 common surgical instruments were divided into two groups: group A (n = 60), and group B (n = 60). All of them were washed with the first washing enzyme bubble ultrasonic wave washing and acidified water soaking disinfection pure water washing method. The effect of each group was checked by corrected vision method and occult blood test paper method. SPSS15.0 software was used for statistical analysis. Results the method of corrected visual acuity showed that the longer the storage time was, the higher the positive rate was after washing (蠂 2 10.909 / 20.297 P 0.05). The positive rates of group B were 85.0% and 60.0% respectively, which were higher than that of group A (55.0%) (P0.05). The positive rate of occult blood test paper was 15.0 55.0% and 92.5% at 6 h, respectively, which was higher than that of corrected visual acuity method (30.0%, 57.5%, P0.05). Conclusion the longer the operation instrument is placed, the worse the cleaning effect is. The wet treatment before cleaning can improve the cleaning effect, and the cleaning effect by using occult blood test paper method is better than that of corrected visual acuity method.
