Lumen Cleaning

Comparison of Current Methods for Pre-Cleaning and Flushing of Lumened Devices

Comparison of Current Methods for Pre-Cleaning and Flushing of Lumened Devices

Flexible endoscopes, rigid endoscopes, lumened robotic devices and other reusable diagnostic tools with channels are inherently challenging to clean. And yet, all the science points to the importance of effective pre-cleaning as a requirement for successful disinfection and/or sterilization, and this science informs the guidelines of thought-leading infection-prevention organizations. For example, ANSI/AAMI ST79:2010 guidance states:

  • 7.5.1: “For all reusable medical devices, the first and most important step in decontamination is thorough cleaning and rinsing… The purpose of cleaning and rinsing is to remove all visible debris… and to reduce the number of particulates, microorganisms and potential pyrogens.
  • Unless otherwise specified… lumened devices should be cleaned … followed by flushing with the appropriate cleaning solution, and then flushed, preferable with treated water, to remove chemicals and/or debris remaining in the lumen.”

Endoscopic device manufacturers are more specific in their instructions for use (IFU), which call for copious flushing, often of at least 250cc of fluid. There are currently three methods of channel/lumen flushing available, but they offer vastly different benefits and challenges:
