STERILIZING A CLINITRON AIR-FLUIDIZED BED WITH COLISTINE POWDER

After cross-patient infection occurred with the Clinitron bed, we look ed for a way to deliver an antibiotic agent into the inner environment of the Clinitron bed through the filtering system in a manner that wo uld sterilize the contaminated microspheres. Multiple cultures of the contaminated microspheres from the Clinitron air-fluidized bed were do ne, and the infecting microorganisms were identified. The appropriate antibiotic powder was delivered through the filter system of the bed, and the microspheres were recultured after treatment. After an antibio tic powder was administered, the microspheres cultured were sterile. W e found that the Clinitron bed can be safely, easily, and inexpensivel y sterilized and reused by the administration of antibiotic agent thro ugh the air filter system. Furthermore resistant bacteria can be treat ed with antibiotic agent sparingly used in a clinical setting because of toxicity.
