[The current epidemics of nosocomial infection in the field of surgery]

Abstract

We studied retrospectively the hospital acquired MRSA and Pseudomonas aeruginosa infections in patients of surgery field. The causative bacteria of nosocomial infections were mainly MRSA and P. aeruginosa. MRSA was mainly cross-infected via the route of medical staffs' hands. P. aeruginosa was mainly infected through indirect contact by wet hospital environment. Therefore, MRSA nosocomial infections can be prevented by washing and disinfecting hand, and disinfecting the dry regions of hospital environment around patients with MRSA infection. P. aeruginosa nosocomial infections can be prevented by washing and disinfecting hands, and disinfecting the wet regions of hospital environment. Urinary indwelling catheter must be aseptically managed for preventing the infection. These various preventive measures controlled the nosocomial infection by MRSA or P. aeruginosa.
