【Abstract】 QBJECTIVE To explore factors and agents of multi-bacterial infection in integration intensive careunit.METHODS Factors and agents of multi-bacterial infection in integration intensive care unit of our hospital during the last 3 years were retrospectively investigated. RESULTS Among 844 nosocomial infection cases,278 were caused by multi-bacterial infection (32.94%). Aging,long-period hospitalizing,accompanying with some underlying diseases,substantive using of antibiotics,hormone and immunity-depressive agents,and invasive treatment were all risk factors of multi-bacterial infection. CONCLUSIONS Positive treatment of underlying disease should be considered since multi-bacterial infections were hard to control. Rational using of drugs according to drug sensitivity test and strict sterilization and isolation measures should be taken to decline infection chances of multi-bacterial infection.更多还原
