Abstract:
Objective To observe the corrosion reaction and disinfection effect of the two different chlorine disinfectants toward the surgical instruments, to prevent the corrosion of instruments and the professional infection risk of cleaning staffs during washing the infectious disease-contaminated medical instruments manually in the primary hospitals. Methods The surgical instruments were soaked in the diluted chlorine effervescent tablets and the diluted chlorine disinfection powder, respectively. The corrosion of the two disinfectants to the equipment at different times was observed. The bloody surgical instruments were soaked in the diluted chlorine effervescent tablets and the chlorine disinfection powder for 4 hrs, respectively. The instruments' surfaces status was observed,and the bacterial reproduction status after soaking the instruments in the diluted liquid for 48 hrs was monitored.Results The diluted liquid of effervescent chlorine tablets had corrosion reaction after only 5- 10 minutes,but the diluted liquid of chlorine disinfection powder had no corrosion reaction after 48 hours. The dilution liquid of effervescent tablets and the dilution liquid of disinfection powder had a significant statistic difference in the rate of instruments corrosion. The bloody instruments' surface had difference after immersed for 4 hrs,and the pass rates of bacteria monitor was 100% after 48 hrs of immersion. Conclusions For the primary hospitals without cleansing and disinfection equipments,using the chlorine disinfection powder to soak the medical instruments before cleaning the infectious disease-contaminated medical instruments manually not only has no equipment corrosion but also achieves the disinfection effect.
