To explore the cleaning method of gastroscope cleaning "blind area", to ensure the effect of endoscopic cleaning and disinfection. Methods 60 cases of contaminated electronic gastroscope after diagnosis and treatment were divided into control group and observation group according to random number method. Control group: The contaminated endoscopes were cleaned and disinfected according to the 2004 edition of "Technical Operation Specification for Cleaning and Disinfection of Endoscopes. Observation group: on the basis of enzyme washing, gauze dipped in diluted multi-enzyme lotion (1: 150) was used to repeatedly scrub the cleaning "blind area" of gastroscope (operation part, clamp opening, apex part, suction and air supply and water supply opening). The two groups were sampled in the "blind area" after the end of the second wash, and the bacterial culture count and ATP bioluminescence method were used to detect the disinfection effect. Results The bacterial culture count and ATP bioluminescence reading values of the observation group were significantly lower than those of the control group (P <0.05). Conclusion The use of multi-enzyme cleaning liquid to repeatedly wipe the "blind area" of gastroscope cleaning can significantly improve the quality of endoscopic cleaning and disinfection, and ensure the effect of endoscopic cleaning and disinfection.
