How quickly can OPA achieve high-level disinfection?

High-level disinfection using ortho-phthalaldehyde (OPA) is achieved effectively within a time frame of 12 minutes. OPA is a chemical agent commonly used in reprocessing flexible endoscopes due to its ability to provide rapid microbial inactivation. It is particularly valued for its effectiveness against a broad spectrum of pathogens, including bacteria, viruses, and fungi, in a relatively short period.

In practice, the 12-minute contact time is crucial because it balances the need for efficient disinfection with the efficacy of OPA against various microorganisms. This optimized time ensures that the endoscopes are adequately disinfected before they are used on patients, thereby minimizing the risk of transmission of infections.

Understanding the specific contact time required for OPA is essential for healthcare professionals involved in endoscope reprocessing, as proper adherence to these guidelines is critical to maintaining patient safety and achieving regulatory compliance.
