Thirty-five cases of postoperative infection with MRSA treated at our department during the last 36 months were studied. When this period was divided into 6 stages, in stage I, MRSA infection were seen in 4.3% of cases, including 6 cases of infectious enterocolitis. In stage II, although severe MRSA infections decreased in number as a result of adequate use of third-generation cephems, the incidence increased to 6.6% because of infection in wounds and in the respiratory tract. During stage III, we made an attempt to isolate MRSA from floating bacteria in the air around patients, and had a suspicion of nosocomial infection originating from the recovery room. Therefore we undertook general management regimens against nosocomial infections, isolated patients infected with MRSA and at the same time, sterilized the recovery room. As a result, the incidence of MRSA infection was decreased to 0% in stage VI. There were no more MRSA carriers among medical staff or nosocomial infections in the recovery room. These results showed that the adequate use of antibiotics and some regimes against nosocomial infections, including the isolation of infected patients and sterilization of the recovery room, are very effective for the prevention of postoperative MRSA infection.
