Veterinary medicine applies sterilization protocols that are comparable to those used in human healthcare but makes adjustments to address animal treatment specific challenges. Key guidelines include:
Thorough cleaning of instruments to eliminate organic matter like blood and tissue is necessary before autoclaving.
Veterinary instruments require a Sterility Assurance Level of 10⁻⁶ which ensures that microorganisms have only a one in a million chance of surviving.
Autoclaves require regular testing through methods like spore tests to verify proper operation.
オートクレーブ（蒸気滅菌）：
Veterinary clinics favor autoclaving because it functions efficiently and consistently.
The sterilization method works for surgical instruments and stainless steel tools as well as certain plastic materials.
化学滅菌：
Used for heat-sensitive items like endoscopes.
The method uses sterilization agents like ethylene oxide (EtO) or hydrogen peroxide gas plasma.
Cold Sterilization:
Involves soaking instruments in chemical solutions.
Cold sterilization serves as the preferred method for sanitizing non-critical instruments which do not enter tissue during use.
The environment in veterinary clinics presents specific challenges which threaten the maintenance of sterility.
Animal fur and dander pose a contamination risk to sterile storage locations.
Instruments used during procedures can become contaminated with blood and saliva alongside other bodily fluids.
When instruments undergo repeated relocation between various spaces they become more susceptible to contamination exposure.
Veterinary environments typically maintain fewer controls compared to human healthcare facilities. Common issues include:
Staff risk contaminating sterile instruments by touching them with their bare hands or using gloves that have been contaminated by animal fluids.
Instruments are stored in environments with variable temperatures and humidity levels as well as exposure to potential contaminants.
The packaging condition and material type during autoclaving processes determine the level of sterility achieved. Veterinary clinics use sterilization pouches or wraps to maintain sterility but these materials must remain unbroken to be effective.
The length of time veterinary instruments retain sterility after autoclaving relies heavily on how they are packaged and stored.
殺菌パウチ：
A clean dry environment allows instruments to keep their sterility for up to six months.
Double-Layer Sterile Wraps:
If stored under ideal conditions instruments can maintain sterility for as long as 1年.
硬質容器：
Rigid containers deliver the longest sterility period which usually lasts more than one year when sealed properly.
Use High-Quality Packaging:
Select sterilization pouches, wraps or containers that veterinary instruments were specifically designed for.
Ensure packaging is sealed correctly before autoclaving.
Store Instruments Properly:
Sterilized items need storage in environments that maintain cleanliness and proper temperature control.
Keep sterilized instruments away from animal contact and high-traffic zones.
取り扱いを最小限にする：
Lower the number of times sterilized instruments are handled to maintain their sterile condition.
Handle all items with protective gloves or sterile equipment to maintain safety standards.
Before autoclaving and after the process, perform an inspection of the packaging to identify any tears or punctures and ensure that seals are properly intact.
Sterilized instruments need clear labeling with their autoclaving date to monitor sterility duration.
Keep storage cabinets and shelves free of dust, fur and contaminants to maintain cleanliness.
The storage area must remain between 15°C to 30°C (59°F to 86°F) and sustain a humidity level of 30% to 60% relative humidity.
Conduct regular training sessions to educate staff about appropriate handling and storage methods.
Sterile packaging should remain closed until the instrument inside needs to be used.
Veterinary settings need diligent care in instrument packaging and storage methods to keep autoclaved instruments sterile. Animal care environments present unique challenges including exposure to fur, fluids, and high-risk areas which necessitate strict adherence to best practices and industry standards.
By implementing these guidelines, veterinary clinics can ensure the safety and effectiveness of their instruments, protecting both animals and staff.
For general guidelines on sterility duration across all settings, check out our related article:
Sterilized instruments can remain sterile for up to 6ヶ月 in pouches or 1年 in double-layer wraps or rigid containers, provided they are stored properly.
Yes, exposure to animal fur, dander, and fluids can compromise the sterility of instruments. Proper storage and handling are essential to minimize contamination risks.
Store sterilized instruments in a clean, temperature-controlled environment, away from animals and high-traffic areas.
Autoclaves should be tested regularly, typically weekly, using biological indicators (e.g., spore tests) to ensure proper sterilization.
