Glutaraldehyde fumigated alexipharmic ark sterilization failure reason analysisAbstract: objective to explore the causes of failure of sterilization, summarize the experience. Methods: glutaraldehyde fumigated ark not resistant to high instrument sterilization 3 hours later sampling bacteria, Every sampling 3-6 times, monthly, unqualified tracking monitoring. For three years, summarize statistical monitoring results from each link analysis for glutaraldehyde fumigated alexipharmic ark sterilization, formulate measures for failure. Results: the glutaraldehyde fumigated alexipharmic ark sterilization rate is low, and the monitoring declined year by year, 2006 and 2007, the sterilization rate in 2008 98.7% respectively, 96.5% and 16%. For glutaraldehyde alexipharmic ark, the factors affecting the effect is not reliable disinfection, stop using eliminated glutaraldehyde fumigated alexipharmic ark. Conclusion: glutaraldehyde fumigated alexipharmic ark sterilization effect is not stable, use after cleaning, maintenance; regularly. According to the strict disinfection technology norms of endoscopic cleaning laparoscopic, Perfect glutaraldehyde was the alexipharmic ark monitoring method, find out hidden trouble. Attention fumigated the daily maintenance of ark, be careful not to advance.Keywords: glutaraldehyde was the alexipharmic ark laparoscopic sterilization failures
