Contamination test of console in clean room after transporting from Outside

Abstract

When blood purification is needed after early stage of hematopoietic stem cell transplantation, it is performed in clean room (CR) because of protection from infectious diseases. We examined the contamination test for console in clean room after transporting from outside. After cleaning console by two kind of disinfectant detergent, the surface hygiene test with relative light unit (RLU) was measured with Adenosine Triphosphate and Adenosine Monophosphate. A permissible range of them is from 200 to 500 RLU. Even though just after disinfecting some data were exceeded over the permissible range, the RLU after 15hours were within the permissible range in all of the places and disinfectant detergent. It is considered that we can control CR atmosphere in the permissible range, cleaning console by disinfectant detergent just before transporting into CR, and infectious risk for the patient in CR would be decreased.
