Sterilization
■ Liquid Chemical Sterilization
Remove obvious contamination by using the cleaning procedure described previously. Select a
sterilant that your hospital or institution has found to be effective for liquid chemical sterilization of
operating room equipment. Buffered gluteraldehyed (e.g. Cidex or Hospisept) has been found to
be effective. Do not use quaternary cationic detergents such as zephiran chloride. If the whole unit
is to be sterilized, immerse the transducer but not the electrical connector into the sterilant for the
recommended sterilizing period. Be sure that the dome is removed. Then rinse all transducer parts
except the electrical connector with sterilize d water or saline. The transducer must be thoroughly
dried before storing.
■ Gas Sterilization
For more complete asepsis, use gas sterilization.
Remove obvious contamination by using the cleaning procedure described previously.
To
inhibit
the formation of ethylene glycol when ethylene oxide gas is used as the disinfectant, the
transducer should be completely dry.
Follow the operating instructions provided by the manufacturer of the gas disinfectant.
