Two different methods of cleaning and disinfection of endoscopy study of terminal disinfection

摘要

200 sets of used gastroscopes for gastroscopy were randomly divided into group A and B, 100 sets in each group. Gastroscopes in group A were cleaned and disinfected with the conventional method and those in group B were cleaned and disinfected with a modified cleaning and disinfection method. On the basis of the conventional method, the modified cleaning and disinfection method was supplemented a booster pump and a cleaning spray gun to replace the syringe for the suction-infusion in the conventional method, and the sterilization effects of two methods were studied and compared. The results showed that the gastroscope sterilization qualified rate achieved with the modified cleaning and disinfection method was 98%, that with the conventional cleaning and disinfection method was 78%, and there was a statistically significant difference in the qualified rate between the two groups (p < 0.05); the incidence of complete and incomplete air/water pipes of gastroscopes in group B was significantly lower than that in the control group (group A) (p < 0.05). The modified method for the cleaning and disinfection of gastroscopes shows a better disinfection effect, lower cost and strong practicability, worthy of clinical popularization.
