Risk factors and drug resistance of enterobacter cloacae infection in ICU

Objective To study the antimicrobial susceptiblity,clinical and bacteriological characteristics of enterobacter cloacae infection in ICU. Methods 83 cases of ICU infected with enterobacter cloacae were analyzed retrospectively. Results The elderly, hypoproteinemia,invasive operation,long-term hospitalization and the abuse of broad-spectrum antibiotics were the risk factors of infection with enterobacter cloacae. Besides highly sensitive to imipenem, the bacterium was resistant to most antibiotics, many of whose drug resistance ratio is over 50%. Conclusion The patients in ICU should be avoided the long-term abuse of broad-spectrum antibiotics and invasive operation.Bacterial culture and antibiotic susceptibility test should be carried out promptly. They could reduce the incidence of enterobacter cloacae infection. Key words: Enterobacter cloacae;  Drug resistance;  Risk factor
