Abstract:
ObjectiveTo evaluate the disinfective effect of a new peracetic acid solution for digestive endoscope.MethodsForty endoscopes were divided into experimental group and control group,10 gastroscopes and 10 enteroscopes in each group,the experimental group was disinfected with the new peracetic acid solution for 10 min,the control group was disinfected with 2％ glutaral for 10 min,the disinfection effect was compared.Subsequently,80 other endoscopes were divided into 4 groups,10 gastroscopes and 10 enteroscopes in each group,each group was disinfected for 2 min,3 min,4 min and 5 min,the disinfection efficiency was evaluated.ResultsThe disinfection rates of gastroscopes and enteroscopes in the control were 100％ (10/10)and 90％ (9/10)respectively.Bacteria were found in both endoscopes.In the experimental group,disinfection rates of both gastroscopes and enteroscopes were 100％ (10/10),and no bacterium was found,which was superior to the control.disinfection rates of gastroscopes of 3 min,4 min and 5 min were all 100％ (10/10),which were higher than that of 2 min group (30％) (P ＜0.05).Bacteria were found in 3 min group.Disinfection rates of 4 min and 5 min group were 100％ ( 10/10),which were higher than that of 3 min group (80％)(P ＜0.05).Bacteria were found in 4 min group,and 2 min group was not disinfected.ConclusionThe new peracetic acid solution is effective for clinic digestive endoscope disinfection,and is superior to 2％ glutaral.
