What is the primary method of removing organic material during the pre-cleaning phase?

The primary method of removing organic material during the pre-cleaning phase is physical scrubbing. This method is crucial because it enables the effective removal of blood, mucus, and other organic materials that may be present on the flexible endoscopes. By using physical scrubbing, healthcare professionals can ensure that debris is dislodged from lumens, channels, and surfaces where it can otherwise impede effective cleaning and disinfection.

While using chemical detergents, soaking in disinfectant, and rinsing with water are all important steps in the overall cleaning process, they often follow the initial physical scrubbing. Chemical detergents may aid in breaking down organic materials, and soaking or rinsing can help remove residual debris, but the insistence on physical scrubbing highlights the necessity of mechanically displacing contaminants first to ensure a thorough and effective cleaning process before any chemical agents are applied.
