硅油附着眼科手术器械清洗方式及评价方法的研究

目的 探讨硅油附着眼科手术器械的最佳清洗方式及有效评价方法。 方法 将400件硅油附着眼科手术器械随机分成A、B、C、D共4组,A组采用标准清洗法,B组采用碱性清洗剂预洗+标准清洗法,C组采用预处理清洗剂预洗+标准清洗法,D组采用95%乙醇溶液与预处理清洗剂预洗+标准清洗法。并采用目测法、触摸法及挂水法评价上述4种清洗方式对硅油附着眼科手术器械的清洗效果。 结果 4种清洗方式对硅油附着眼科手术器械的清洗合格率比较,差异有统计学意义（P<0.001）,其中D组清洗合格率最高。3种方法评价清洗合格率结果为目测法98%,触摸法100%,挂水法97%;3种评价方法消耗时间的比较,挂水法平均耗时最短,为10.1 s/件。 结论 硅油附着眼科手术器械的清洗推荐采用95%乙醇溶液与预处理清洗剂预洗+标准清洗法;针对硅油清洗效果的评价方法推荐使用挂水法。

Study on cleaning methods and evaluation approaches of silicone oil-attached ophthalmic surgical instruments

Objective To explore the optimum cleaning methods and effective evaluating approaches for silicone oil-attached ophthalmic surgical instruments. Methods 400 pieces of silicone oil-attached ophthalmic surgical instruments were randomly allocated into 4 groups,namely group A,group B,group C and group D. The standard cleaning method was used in group A;alkaline detergent immersion and standard cleaning method were used in group B;pretreatment detergent immersion and standard cleaning method were used in group C;Group D received 95% alcohol wet gauze wiping combined with pretreatment detergent immersion and standard cleaning method. The effects of 4 cleaning methods on silicone oil-attached ophthalmic surgical instruments were evaluated by 3 approaches including visual inspection,touching and water-hanging method. Results The comparison of cleaning methods shows that there were significant differences in qualified rates of silicone oil-attached ophthalmic surgical instruments among the 4 cleaning methods（P<0.001）. The qualified rate of the cleaning method of 95% alcohol wet gauze wiping combined with pretreatment detergent immersion and standard cleaning method is the highest. The results of the 3 evaluation approaches for this cleaning method were as following,the qualified rate of visual comparison method with 98%,touching method with 100%,and water-hanging method with 97%. According to the comparison of evaluation approaches,the average implementation time of the water-hanging method is the shortest（10.1 s/piece）. Conclusion The cleaning method of 95% alcohol wet gauze wiping combined with pretreatment detergent immersion and standard cleaning method is recommended. Moreover,the water-hanging method is suggested to be used as an approach for the detection of silicone oil residue after cleaning.
