目的观察两种不同的内镜灭菌方法的灭菌效果。方法分别用医用灭菌器和20g/L戊二醛对内镜进行灭菌试验。结果用医用灭菌器灭菌30min,用20g/L戊二醛浸泡灭菌10h,内镜和菌片均未检出微生物,合格率100%。结论两种方法灭菌效果均可靠,但医用灭菌器灭菌周期短,对人和环境无毒无害,不损坏内镜,是一种高效、快速、简便、经济、安全的内镜灭菌方法。 Objective To observe the sterilization effect of two different endoscopic sterilization methods. Methods Endoscopes were sterilized with medical sterilizer and 20g / L glutaraldehyde respectively. The results were sterilized with a medical sterilizer for 30min and sterilized with 20g / L glutaraldehyde for 10h. No microorganisms were detected in the endoscope and the bacterial cells, with a pass rate of 100%. Conclusion Both methods are reliable in sterilization, but the sterilization cycle of medical sterilizers is short, non-toxic to humans and the environment, and does not damage the endoscope. It is an efficient, rapid, simple, economical and safe endoscopy Bacteria method.
