Key Learning Segments

Disinfection of Ultrasound Probes used for Percutaneous Procedures:
Endoscope Cleaning, Looking Ahead to the Next Gold Standard:


Ultrasound-guided percutaneous procedures encompass a broad and varied group of medical interventions involving the piercing of the skin, under the guidance of ultrasound imaging.  The growth and medical application of these procedures has been considerable.  Understanding and addressing infection prevention practices associated with these procedures has been elusive. This symposium reviews and discusses percutaneous procedures and the disinfection of ultrasound probes utilized during the application of these medical interventions. 

Flexible endoscopes have been associated with the greatest number of patient infections when compared to other reusable medical devices. The body of evidence shows that patient ready endoscopes can remain contaminated despite high level disinfection or sterilization, warranting review of upstream processes. Ineffective manual cleaning of the inner channels is one of the major root causes of biofilm formation and failed disinfection in flexible endoscopes. This session reviews the evidence associated with manual cleaning challenges, and reviews next generation technology for addressing these issues to support patient and staff safety.  

Learning objectives

  • Define the Spaulding Classification System and its foundational role in infection prevention
  • Describe the medical breadth and complexity of percutaneous procedures
  • Discuss the disinfection of ultrasound probes utilized in percutaneous procedures
  • Describe the role of ineffective manual cleaning in infection transmission risk
  • Discuss next generation technology for addressing these problems
