Methods of Sterilization II: Chemical Methods

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Methods of Sterilization I: Physical Methods

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

Medical Devices
Sterilization Technology
Surgical Instruments

Background:

Evolving sterilization technologies raise questions about bone pencil efficacy.
Assessing if new methods meet Centers for Disease Control and Prevention (CDC) standards is crucial.
Comparison between Ethylene Oxide (ETO) gas sterilization and hydrogen peroxide-based Sterrad systems is needed.

Purpose of the Study:

To compare the sterilization effectiveness of Ethylene Oxide (ETO) gas versus hydrogen peroxide-based Sterrad systems for bone pencils.
To determine if newer sterilization methods meet established safety and efficacy standards.

Main Methods:

A standardized number of bone pencils were subjected to both Ethylene Oxide (ETO) and Sterrad sterilization.
Three batches, each containing 13 bone pencils per sterilization group, were utilized.
Post-sterilization cultures were performed at 24 and 48-hour intervals.

Main Results:

No microbial growth was observed on any culture plates for either sterilization method.
Both Ethylene Oxide (ETO) and Sterrad sterilization proved effective in eliminating microbial contamination.

Conclusions:

Bone pencils can be reliably sterilized using both traditional Ethylene Oxide (ETO) gas and newer hydrogen peroxide-based Sterrad systems.
Newer sterilization technologies provide comparable efficacy to older methods for bone pencil sterilization.
The study supports the use of modern sterilization equipment for surgical instruments like bone pencils.
