【摘要】 通过去血渍多酶洗涤剂在染血手术器械清洗上的应用研究,结合卡方检验的统计学方法得到了去血渍多酶洗涤剂清洗手术器械的较佳浸泡条件,洗涤剂质量分数为0.5%,在40℃下浸泡10 min,洗涤剂用量和浸泡温度的实验组间结果差异具有统计学意义(P<0.05),浸泡时间的实验组间结果差异无统计学意义(P>0.05);较佳清洗方式为超声波+多酶洗涤剂浸洗,试纸检测法的A-B,A-C,A-D以及B-D的两两组间清洗合格率差异具有统计学意义;试纸检测法比放大镜目测法更适合用于染血手术器械清洗质量的判断,且自配去血渍多酶洗涤剂的性价比要优于其他5种市售加酶洗涤剂。更多还原

【Abstract】 Optimum soaking conditions for application of blood stain removal detergent formulated with multiple enzymes for cleaning of surgical operation apparatus were obtained via study of experimental test results in combination with chi-square test statistical method.Mass fraction of the detergent is 0.5%.Soaking temperature is 40 ℃ and soaking time is 10 min.Deviation of experimental results from different test groups for detergent dosage as well as for soaking temperature has statistical significance(P<0.05),while that for soaking time has no statistical significance(P>0.05).Optimum cleaning method is soaking using detergent formulated with multiple enzymes and assisted by ultrasonic wave.Cleaning quality was inspected by test paper method.Difference between inspection results from groups A-B,A-C,A-D and B-D obtained by test paper method has statistical significance.Test paper method is more suitable for inspection of cleaning quality of blood stain removal on surgical operation apparatus than method via visual observation with magnifier.The blood stain removal detergent formulated in laboratory is better as comparison with five kinds of detergent product bought from market in view of performance price ratio.更多还原
