强化清洗流程对可复用穿刺针清洗效果的应用观察

目的为改进复用穿刺针清洗效果,对比两种不同清洗流程方法对复用穿刺针的清洗效果,观察研究超声加酶清洗流程的优越性,确保无菌物品的灭菌质量。方法将回收来的可复用的骨穿针、腰穿针100根随机分成两组,对照组和实验组各50根。对照组清洗方法为常规预处理加手工清洗;实验组在常规预处理之后,将穿刺针置于全效多酶洗液中用超声清洗机以70～100 kHz频率清洗5 min。结果通过专业检测、目测及使用光源放大镜检查,对照组合格率84%,实验组合格率98%,两组比较经χ2检验差异有统计学意义(P<0.05)。结论对于管腔狭小的穿刺针,消毒时在常规预处理清洗的基础上,采用多酶液预处理配合超声清洗,污渍残留清除彻底,清洗合格率高,能保证可复用穿刺针灭菌质量。

Cleaning Effect of Different Methods for Reusable Puncture Needles

Objective To improve the cleaning effect for reusable puncture needles by comparing the effect of two different cleaning methods.Methods One hundred recycled reusable bone marrow biopsy/aspiration needles and lumbar puncture needles were randomly divided into two groups,each group had fifty needles.In the control group traditional pretreatment and handed cleaning were used;while in the experiment group the needles were pretreated and then dipped in multiple enzyme detergents washed by ultrasonic cleaner at 70-100 kHz for five minutes.Results The results of the special gauging,visual inspection and magnification inspection revealed that the cleanliness pass rate was 90% in the control group and 98% in the experimental group,the difference was significant by chi-square test(P<0.05).Conclusion For the puncture needles with a narrow cavity,the ultrasonic cleaner with multiple enzyme detergents can thoroughly clear away the residual stains with high pass rate of cleaning,so it can guarantee the cleaning quality of reusable puncture needles.
