Abstract


Objective: To endoscopic disinfection, sterilization basic status of statistical analysis, to explore a variety of endoscopic safety, efficient, practical disinfection, the best way to find the endoscopic disinfection and sterilization, which is within the mirror physicians during surgery to provide a more secure, convenient, fast and endoscopic surgical equipment and devices. Methods: Applied Mathematics statistical methods and mathematical modeling method of survey data processing 1, Guangdong Province Hospital from 2002 to 2004 and 2007 endoscopic disinfection and sterilization comparing the data analysis is increasing year by year; binding around 2001 to 2007 flexible endoscopic disinfection and sterilization survey data, the qualified rate of disinfection curve fitting software Matlab to analyze the current situation, and flexible endoscopy in 2012 the passing rate trend forecast. 2, the operating rooms of 36 major hospitals in Guangzhou City, the investigation of sterilization equipment, study the market share of the low-temperature sterilization equipment; follow-up survey 2005-2008 endoscopic disinfection of a hospital in Guangzhou minimally invasive center off bacteria records, three contrast; analysis of endoscopic disinfection and sterilization equipment ideal configuration. 5, install and run from Spss15 and Matlab statistical data analysis. Results: 1, qualified rate of disinfection of of Guangdong Province soft mirror close to 50%, the soft mirror across the country qualified rate of disinfection same low. If endoscopic cleaning and disinfection of technical operation \; 3, ions and hydrogen peroxide and peracetic acid sterilization effect, was 100%. In the more economically developed areas, low-temperature plasma and peracetic acid sterilization equipment has become endoscopic disinfection mainstay of the market; existing low temperature sterilization methods, peroxide hydrogen plasma sterilization with peracetic acid sterilization The solution is the most advanced method of sterilization; generally only plasma and peracetic acid equipment set that can meet the requirements of general hospital endoscopic surgery. Conclusion: 1, the hydrogen peroxide plasma sterilization with peracetic acid sterilization solution is the most advanced method of sterilization; 2, endoscopy, colonoscopy and other soft lens disinfection of the low pass rate, endoscopic disinfection level has not increased year by year rigid endoscopic sterilization high pass rate; 3, the best endoscopic sterilization methods, does not refer to a certain kind of sterilization, but hydrogen peroxide plasma, peracetic acid and ethylene oxide the combination of the method of sterilization, in order to achieve overall balance of timeliness, safety and economic aspects.
