High-level disinfectants are expected to inactivate all viruses, bacteria (particularly mycobacteria), fungi and, if possible, bacterial spores. In healthcare facilities glutaraldehyde has been used for more than 50 years for high-level disinfecting (and under limited circumstances, sterilization) of endoscopes and other devices. Unfortunately, research is now showing that a number of bacteria are becoming resistant to glutaraldehyde and orthophthalaldehyde (OPA) based highlevel disinfectants.

What Will I Learn?
Reusable medical devices such as flexible endoscopes are widely used in hospitals for diagnostic and surgical procedures. Many of these devices are heat sensitive, so they cannot be terminally processed by steam sterilization. Such devices can be sterilized using low temperature processes or, more commonly, can be high-level disinfected with liquid chemicals.This study guide will discuss the emerging scientific reports of microbial resistance to aldehydes and its impact on human health.
Upon completion of this study guide, the participant should be able to:
1. Define aldehyde-resistant organisms and the facts concerning these microorganisms.
2. Discuss the occurrence of aldehyde-resistant organisms and the steps that are taken to prevent the spread of infection.
