Infection Characteristic,Prevention and Control of 106 Acinetobacter baumannii Strains in ICU / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To analyze the susceptible factors and resistance of Acinetobacter baumannii in ICU,in order to create a novel thought of effective prevention and control of A. baumannii cross-infection. METHODS Specimens were collected from ICU patients with infections from Sep 2006 to Sep 2008. The infection characteristic was analyzed and the drug sensitivity was tested to know the risk factors of infection retrospectively. RESULTS The factors of low immunity,severe wound,invasive operation and using ventilator led to the serious cross-infection of A. baumannii in ICU .In vitro drug susceptibility test,the sensitive rates only to cefoperazone/sulbactam and amikacin were higher. They were 65.09% and 72.64%,respectively. CONCLUSIONS It has great significance in the prevention and control of A. baumannii cross-infection in ICU to strengthen the environment disinfection,were education of nosocomial infection knowledge among medical staff,executeing the hand-washing system strictly,useing the antibiotics rationally,keeping the susceptible crowd and adopting de-escalation strategy of prevention and control.
