Breaking ground in ultrasound probe disinfection:

reducing HPV transmission risk


The Nanosonics sponsored educational webinar was a huge success.  

Sonographers are committed to providing their patients with outstanding care at every examination and procedure. Prevention of infection transmission by adequate disinfection of ultrasound probes forms a key aspect of this care. Recent research has alerted the sonography profession to the higher than anticipated frequency of human papillomavirus (HPV) contamination in both the clinical environment and on transcavity ultrasound probes despite routine disinfection practices. These alarming findings and their significance are discussed in this webinar presented by Distinguished Professor Craig Meyers, who has dedicated his career to understanding the life cycle and survival characteristics of the native HPV virus which causes 99.7% of cervical cancers.

Professor Meyers presented his recent published work and surprising revelations regarding the poor efficacy of some common ultrasound probe disinfectants to HPV, as well as his finding that an automated sonicated hydrogen peroxide system designed for ultrasound probes reproducibly eradicates the virus. This webinar will deal with questions around current disinfectant use in ultrasound reprocessing and how patient care can be improved by working with infection control professionals to establish best practice probe reprocessing methods.
