There are four generally recognized categories of disinfection and sterilization. Sterilization is the complete
elimination of all forms or microbial life including spores and viruses.
Disinfection, the selective removal of microbial life, is divided into three classes:
High-Level Disinfection - Destruction/removal of all microorganisms except bacterial spores.
Mid-Level Disinfection - Inactivation of Mycobacterium Tuberculosis, bacteria, most viruses, fungi, and some
bacterial spores.
Low-Level Disinfection - Destruction of most bacteria, some viruses and some fungi. Low-level disinfection will
not necessarily inactivate Mycobacterium Tuberculosis or bacterial spores.
The following specific recommendations are made for the use of Endocavitary ultrasound transducers. Users should
also review the Centers for Disease Control and Prevention document on sterilization and disinfection of medical
devices to be certain that their procedures conform to the CDC principles for disinfection of patient care equipment.
1. CLEANING
After removal of the probe cover, use running water to remove any residual gel or debris from the probe. Use a
damp gauze pad or other soft cloth and a small amount of mild non-abrasive liquid soap (household dishwashing
liquid is ideal) to thoroughly cleanse the transducer. Consider the use of a small brush especially for crevices and
areas of angulation depending on the design of your particular transducer. Rinse the transducer thoroughly with
running water, and then dry the transducer with a soft cloth or paper towel.
2. DISINFECTION
Cleaning with a detergent/water solution as described above is important as the first step in proper disinfection since
chemical disinfectants act more rapidly on clean surfaces. However, the additional use of a high level liquid
disinfectant will ensure further statistical reduction in microbial load. Because of the potential disruption of the
barrier sheath, additional high level disinfection with chemical agents is necessary. Examples of such high level
disinfectants include but are not limited to:
2-3.2% glutaraldehyde products (a variety of available proprietary products including "Cidex," "Metricide," or
"Procide").
Non-glutaraldehyde agents including Cidex OPA (o-phthalaldehyde), Cidex PA (hydrogen peroxide &
peroxyacetic acid).
7.5% Hydrogen Peroxide solution.
Common household bleach (5.25% sodium hypochlorite) diluted to yield 500 parts per million chlorine (10 cc
in one liter of tap water). This agent is effective, but generally not recommended by probe manufacturers
because it can damage metal and plastic parts.
