In the context of endoscope cleaning, why is it necessary to first use a detergent?

Using a detergent initially during the endoscope cleaning process is crucial because detergents are specifically designed to break down organic matter. Endoscopes often come into contact with bodily fluids, tissue samples, and other organic debris that can cling to their surfaces. By applying a detergent, you facilitate the removal of these substances, ensuring that the endoscope is thoroughly cleaned and prepared for further disinfection or sterilization.

This process not only helps ensure the effectiveness of subsequent cleaning agents but also plays a vital role in maintaining the integrity and functionality of the endoscope. If organic materials are not adequately removed, they can create a barrier that prevents disinfectants from reaching the surfaces that need to be cleaned, potentially risking infection or contamination.

Inadequately cleaning with a detergent could compromise the reusability of the endoscope, but the primary role of the detergent is related to breaking down organic matter rather than promoting reuse or enhancing visibility.
