3As cleaning frequently
involves mixed instrument loads, the efficacy of drying will vary based on the
equipment and the nature and volume of the load being processed. Therefore, the
drying parameters must be determined by observation.
7. Following processing carefully inspect the
instrument for cleanliness, any evidence of damage, and proper operation. If
visible soil remains on the instrument following processing it should be
reprocessed or manually cleaned.
1. Disassemble the instrument as applicable and
inspect the instrument for damage or corrosion.
2. Pre-rinse the instrument by holding it under
cold running water for at least 30 seconds, rotating the instrument to expose
all surfaces and cavities to flowing water. Additional rinsing may be necessary
depending on the size and extent of soiling of the instrument.
3. Place the instrument into a suitable clean
basin filled with fresh neutral pH cleaning solution prepared according to the
directions of the solution manufacturer. Use only cleaning solutions that are
labeled for use with medical devices or surgical instruments. Ensure that the
instrument is fully immersed in the cleaning solution. The following conditions
were validated using a neutral pH detergent (Steris ProKlenz NpH) and a severe
organic soil challenge (Biomedical Instrumentation and Technology
4. Using a soft cleaning brush gently scrub all
surfaces of the instrument while keeping the instrument submerged in the
cleaning solution for at least 5 minutes. Clean the instrument until all
visible soil has been removed.

Package the instrument in a suitable
sterilization pouch or instrument tray.
Unless otherwise indicated in the Directions for
Use provided with the specific instrument, instruments and instrument trays may
be sterilized by the following moist heat (steam) sterilization methods:
- Prevacuum High
Temperature Autoclave: 274˚F (134˚C) for 3 minutes; wrapped.
As per ANSI/AAMI ST79:2010 and A1:2010 270˚F (132˚C) for 4 minutes and 275˚F
(135˚C) for 3 minutes are acceptable minimum cycle times for
dynamic-air-removal steam sterilization cycles.
- Standard Gravity
Autoclave: 250˚F/15.2 psi (121˚C/104.8kPa [1.048 bar]) for 30 minutes;
Speed (Flash) Autoclave: 270˚F/27.1 psi (132˚C/186.8kPa [1.868 bar]) for 10 minutes;
unwrapped, but covered.
- High Vacuum (Pre-vacuum)
Autoclave: 274˚F/30.0 psi (134˚C/206.8kPa [2.086 bar]) for 3
processed in a wrapped instrument tray should be placed within the tray in a
manner that allows steam to contact all surfaces of the instrument. Do not pile
instruments on top of each other as this may block steam penetration and
condensate drainage. Do not overload the tray. Heavily loaded instrument trays
should be processed by high temperature pre-vacuum steam sterilization.
sterilization processing should be reserved for emergency reprocessing only and
should not be employed for routine sterilization processing of the instrument.
Flash sterilized items should be used immediately, and not stored for later
use. See ANSI/AAMI ST79:2010 and A1:2010 and your institution’s
policies for restrictions regarding the use of flash sterilization.
WARNING: Single use
instruments should not be reprocessed.
The instrument and/or instrument tray should be
processed through a complete sterilization drying cycle as residual moisture
from autoclaves can promote staining, discoloration, and rust.
Following sterilization processing packaged
instruments may be stored in a clean area free of temperature and humidity
extremes in accordance with your institution’s policies.
