Central Sterilization uses pre-vacuum sterilization. Each sterilizer undergoes a weekly spore test inoculated with Geobacillus.
-
The results are kept for each sterilizer in a logbook maintained by the Central Sterilization staff.
-
If results are positive, repeat the spore test and examine the procedure to ensure that the sterilizer is loaded properly (not overfilled), the pack is not too large, and the manufacturer’s instructions have been followed.
-
If the results are positive again, do not use the sterilizer until it has been inspected or repaired. Using another sterilizer, reprocess any items sterilized since the last negative spore test.
-
A challenge pack is placed in every load before sterilization.
-
The load cannot be released for use until the challenge pack has been verified for all parameters of sterilization have been met.
-
The challenge packs are kept in a logbook for reference.
-
Class V indicators are placed inside sterilization bags that have been packaged in CS.
