Physical-technical investigations into ultrasound-induced aerosol formation from ultrasonic baths used in the medical setting

Abstract
Ultrasonic baths (ultrasonic cleaners) are commonly used in hospitals and outpatient settings for cleaning and disinfection of medical instruments. Time and again the question is asked as to whether there is a likelihood of ultrasound-induced aerosol formation, and associated microbial emission into the room air, presenting a hazard to medical personnel. To date, there have only been isolated investigations into this issue, but these have produced contradictory findings. The aim of the present study was therefore to provide an answer, from a physical-technical perspective, as to whether personnel really faces this supposed risk. The results demonstrate that there is no physical evidence of ultrasound-induced aerosol formation from commercially available ultrasonic baths, when operated as instructed to process medical instruments, with typical ultrasonic frequencies of between 35 kHz and 40 kHz, power densities up to around 60 W/l and water temperatures up to 45 C. The first particles were visually detected leaving the ultrasonic bath as from a water temperature of above 50 C. It is recommended that a lid be used as from that temperature range.

Monitoring of steam sterilization processes in the dental office

Abstract
In dental offices steam sterilization is used to prevent infection of staff and patient. The necessity of sterilization is obvious. To ensure effective sterilization processes each load has to be monitored. Based on literature and standards a state of the art concept of every load monitoring is described.
