As a distributor, dealer, or purchaser of medical instruments you must understand these principles to maintain compliance and ensure patient safety.
Sterilization denotes the complete removal of microbial life such as bacteria, viruses, fungi, and spores from any surface or instrument. Medical and industrial environments rely on this procedure to stop infections and protect both patients and equipment users.
The Sterility Assurance Level (SAL) functions as a standard metric for determining the likelihood that a single microorganism will survive on an item after sterilization. Medical instruments require an SAL of 10⁻⁶ which indicates there is one chance in a million for a surviving microorganism.
Autoclaving (Steam Sterilization):
Operates through high-pressure steam which reaches temperatures between 121°C and 134°C.
Effective for most medical instruments.
Chemical Sterilants:
Chemical sterilants consist of ethylene oxide (EtO), hydrogen peroxide gas plasma and peracetic acid.
Suitable for heat-sensitive instruments.
Dry Heat Sterilization:
Uses high temperatures without moisture.
Dry Heat Sterilization works best for instruments that could become damaged when exposed to steam.
Radiation Sterilization:
Utilizes gamma rays or electron beams.
Common in industrial settings for pre-packaged items.
Though each sterilization method presents distinct strengths and weaknesses, keeping items sterile after sterilization remains crucial.
The packaging choice during sterilization determines the ability to maintain sterility. Common options include:
Sterile Wraps or Pouches function as barriers against microorganisms and enable sterilizing agents to reach the contents inside.
Rigid Containers serve as a durable and reusable storage solution for sterilized instruments in healthcare facilities.
The instrument loses its sterility when packaging develops tears or punctures or fails to seal properly. Performing routine inspections on packaging materials is crucial to maintain their protective function.
Adequate storage conditions play a vital role in preserving the sterile status of medical instruments. Key considerations include:
Sterilized instruments must be kept in a regulated environment with temperatures ranging from 15°C to 30°C.
When humidity levels rise they can damage packaging materials and enable microbial development. Aim for a relative humidity of 30–60%.
Keep instruments in a clean space without dust to reduce the chances of contamination.
Sterility can become compromised despite proper packaging and storage when handling practices remain inadequate. To minimize risks:
Avoid handling sterilized instruments with bare hands. Use gloves or clean tools.
Minimize exposure to contaminants by storing instruments in low-traffic zones.
Develop explicit procedures for the inspection and management of sterilized items.
The amount of time items remain sterile depends on both packaging type and storage environment.
When stored correctly instruments in sterile wraps or pouches maintain sterility for approximately six months.
Rigid Containers have the ability to remain sterile for 12 months when stored under perfect conditions.
These timeframes represent general guidelines which should be followed. The manufacturer’s instructions and industry standards must be followed at all times.
The Centers for Disease Control and Prevention (CDC) along with the Association for the Advancement of Medical Instrumentation (AAMI) set guidelines which organizations should follow to maintain sterility. Ensure best practices by frequently reviewing these standards.
Maintaining sterile medical instruments is a crucial duty for distributors, dealers, and buyers. The length of time a product remains sterile varies based on the conditions of its packaging, storage environment and handling methods. Following established industry standards and proper protocols helps maintain instrument sterility and protects both patients and users.
For more specific information on autoclaving and its impact on sterility duration, check out our related article:
Inspect the packaging for tears, punctures, or signs of moisture. If the packaging is compromised, the instrument should be re-sterilized.
Proper storage and handling can help maintain sterility for the recommended duration, but extending beyond the manufacturer’s guidelines is not advised.
If contamination is suspected, immediately re-sterilize the instrument to ensure safety.
Yes, sterilized instruments should be stored in a clean, temperature-controlled environment with low humidity.
Regular inspections are recommended, especially before use, to ensure the integrity of the packaging.
