Investigation on Staphylococcus Nosocomial Infection and the Risk Factors in Burn Patients

OBJECTIVE To control the nosocomial infection caused by meticillin-resistant Staphylococcus in burn patients. METHODS The specimens of burn wound excreta, urine, stool and blood of burn patients were collected to isolate pathogenic organisms and the susceptibility tests for antibacterial agents were performed by Kirby-Bauer method. RESULTS The rates of meticillin-resistant Staphylococcus(MRSA) and meticillin-resistant coagulase-negative Staphylococcus(MRCNS) were 89.4% and 60%. CONCLUSIONS Staphylococcus may cause infections in burn wound, urinary tract, respiratory tract, the alimentary canal and blood. Most of them are MRSA and MRCNS and multidrug resistant. Severe burn, abuse of third-generation cephalosporins and fluoroquinolones and long hospital stay may be the risk factors for staphyiococcal nosocomial infections.
