Thorough cleaning of endoscopes is a prerequisite for ensuring disinfection efficacy. The main factors affecting the effect of endoscopic cleaning are the type and degree of endoscopic contamination, whether it is wet enough before cleaning, flushing pressure, time, technical proficiency and quality of manual brushing. If the endoscope cannot be cleaned effectively in time after use, blood, digestive juice and various microorganisms will breed in the cavity and surface of the endoscope, forming a biological protective film, hindering the penetration of disinfectant, resulting in incomplete disinfection. Macular spots are also easy to form on the surface of the endoscope. Macular spots are the result of coagulation reaction between human secretory residues and disinfectant glutaraldehyde, which not only shortens the service life of the endoscope, but also affects the disinfection quality of the endoscope, increase the chance of iatrogenic infection. Pretreatment is the key link to ensure the cleaning effect. Pretreatment has laid a good foundation for the upcoming cleaning and disinfection work. Using multi-enzyme as pretreatment can effectively loosen and remove the protein, mucopolysaccharide, fat, etc. adhered to the surface of the endoscope, and increase the ability to remove microorganisms on the surface of the object during cleaning. Secondly, the multi-enzyme is retained in the lumen of the endoscope, and there is enough time to quickly decompose the pollutants, reducing the biological load on the surface of the object can ideally remove the microbial contamination that is difficult to distinguish with the naked eye, effectively remove the dirt on the outer surface and lumen of the endoscope, and improve the quality of endoscopic cleaning. Studies have shown that the content of multi-enzyme cleaning agent has a very obvious effect on the cleaning effect. The main cleaning principle of multi-enzyme cleaning agent is to decompose the macromolecular water-insoluble pollutants into small molecules and soluble in water through the decomposition of enzymes. Microorganisms on endoscopes, especially blood-borne pathogens, are infected through organic substances such as saliva and blood when checking positive patients. When cleaning, multi-enzyme cleaning liquid can fully decompose the dirt and remove it from the endoscope. In the study of experts, without the use of disinfectant and only through the standard cleaning, endoscopes have a certain number of specimens have not detected pathogenic bacteria, can be considered through full cleaning can achieve the standard of endoscopic cleaning and disinfection. Multi-enzyme pretreatment for the role of digestive endoscopy, with multi-enzyme pretreatment of digestive endoscopy can be organic secretions in a short period of time to quickly decompose, not only make the surface of the endoscope clean and bright, the average number of bacteria in the endoscope is also significantly reduced, improve the cleaning and disinfection effect. Dipped in multi-enzyme stock solution scrubbing makes the lubricating degree of the cleaning brush increase in the pipeline, and the scrubbing is smooth, concise and convenient, which effectively shortens the scrubbing time. Through this study, we believe that multi-enzyme pretreatment for digestive endoscopy can significantly improve the cleaning effect of endoscopes and the work efficiency of decontamination personnel, also reduce the wear and tear of endoscopes and the loss of cleaning brushes, and effectively extend the service life of endoscopes and accessories, which is worthy of clinical promotion.
