The Chemistry of Cleaning



The purpose of this education activity is to provide information and guidance to program participants to help them select the appropriate medical detergents for pre-treatment, manual and automated cleaning, and biofilm removal from flexible endoscopes. The focus on chemistry will provide a foundation of knowledge about the differences in cleaning action and chemical properties that will support best practice in the gastrointestinal endoscopy suite.

Target Audience

This CNE activity is intended primarily for RNs with a responsibility for or an interest in endoscope processing and ensuring safe patient care in the endoscopy suite. The presentation will also be of interest to allied healthcare personnel and MDs involved in endoscopy.

Learner Objectives

Upon completion of this presentation, participants will be able to:

1) Identify characteristics of detergents used in flexible endoscope reprocessing

2) Compare enzymatic, non-enzymatic, and alkaline+ surfactant detergents.

3) Discuss the impact of biofilm on capacity of medical detergents to clean GI and other flexible endoscopes in preparation for high-level disinfection or sterilization.
