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...

Context:

Ethylene oxide sterilization is widely used but has limitations.
Wet sterilization methods can lead to recontamination.
Thermolabile instruments require specialized sterilization techniques.

Purpose:

To evaluate the suitability of GDR-produced packing materials for gaseous formaldehyde sterilization.
To confirm the microbiological reliability of selected packaging for sterile instruments.
To identify an appropriate packing variant for formaldehyde sterilization.

Summary:

Gaseous formaldehyde sterilization is a viable alternative for thermolabile instruments.
Selected GDR packing materials were tested for germ-tightness and toxicological safety.
An effective packing variant was identified and validated for microbiological reliability.
Sterilization in recontamination-proof sterile packing is a key advantage.

Impact:

Provides a validated method for sterilizing sensitive medical instruments.
Ensures the integrity and safety of sterile medical supplies.
Contributes to improved infection control practices in healthcare settings.
