[摘要] 目的 探讨重症单元使用后的麻醉喉镜在消毒供应中心集中清洗、消毒之后的效果，分析其方法的应用性。方法 把重症单元送至供应中心处理的麻醉喉镜经初步清洗后随机分成A、B两组，A组共41片，B组40片，A组经全自动清洗消毒机清洗消毒后做细菌培养；B组经环氧乙烷灭菌后做细菌培养，将两组麻醉喉镜做细菌培养后的菌落数（cfu）进行对比分析。 结果 A组喉镜细菌培养结果仅出现1片菌落数≥1 cfu/cm2，实际菌落数为10 cfu/cm2，经进一步培养为大肠杆菌，合格率为97.56%，B组喉镜细菌培养结果菌落数全部小于1 cfu/cm2，合格率100%，两组合格率比较差异无统计学意义（P>0.05）。 结论 麻醉喉镜片由自动清洗消毒机消毒处理和环氧乙烷灭菌效果无显著性差别。

[Abstract] Objective To investigate the effect of anesthesia laryngoscope after use in intensive care unit in central cleaning and disinfection of disinfection supply center and analyze the applicability of the method. Methods The anesthesia laryngoscopes sent from the intensive care unit to supply center were randomLy divided into group A and group B after the initial cleaning， with 41 tablets in group A and 40 tablets in group B. The bacterial culture was performed for the anesthesia laryngoscopes in the group A after disinfection of automatic cleaning and disinfection machine. And the bacterial culture was performed in the group B after sterilized with ethylene oxide. The number of colonies（cfu） of two groups of anesthesia laryngoscopes after bacterial culture was compared and analyzed. Results The bacterial culture results in group A showed only one colonies ≥1 cfu/cm and the actual number of colonies was 10 cfu/cm2. The bacteria were further cultured as E. coli， with the pass rate of 97.56%. The bacterial culture results in group A showed that all colonies were less than 1 cfu/cm2， with the pass rate of 100%. There was no difference between the two groups in the the pass rate（P>0.05）. Conclusion There is no significant difference in the effect between the disinfection of the cleaning and disinfection machine and the ethylene oxide sterilization on sanesthesia laryngoscope.

隨着医疗技术水平的飞速发展，在麻醉情况下用喉镜进行气管插管在临床上也得到了很大的普及，特别是在重症护理科室应用越来越广泛。但是在临床应用中也带来了一个共性问题，就是麻醉喉镜是黏膜接触类医疗用品，需要达到高水平的消毒后方可以再次使用，对使用后的麻醉喉镜如何进行高水平的消毒，目前还没有一个公认满意的方法[1-3]。为寻找一种快速、简单、有效的麻醉喉镜消毒方法，我中心用全自动清洗消毒机清洗消毒喉镜，并与环氧乙烷灭菌效果进行了对比，现报道如下。
