RESUMO
[Objective] To compare the disinfection effect of different disinfectants on disinfection effect of laryngeal endoscope,and seek for a more safe and effective disinfectant for laryngeal endoscope.[Methods] 180 laryngeal endoscope were divided into three groups with 60 of them in each group.Acidic electrolyzed oxidizing water(AEOW),2％ glutaraldehyde and orthophthalaldehyde were used for disinfection.Three minutes and five minutes after disinfection,the samples were got and underwent bacterial detection.The disinfection effect after three minutes and five minutes was compared.[Results] The qualified rate of disinfection and cost between AEOW,2％ glutaraldehyde and orthophthalaldehyde showed distinct difference.[Conclusions] Using acidic electrolyzed oxidizing water in the disinfection of laryngeal endoscope has advantages of fast,effective,low-cost,which can be applied in the clinical work.
