Analysis of Risk Factors for Lung Infection of CRAb in ICU / 中国药房

ABSTRACT

OBJECTIVE:To discuss the risk factors for lung infection of CRAb in ICU,and to provide reference for clinical di-agnosis and treatment. METHODS:The univariate analysis and multivariate Logistic regression analysis were conducted with the method of case-control study,in which the clinical data of 105 cases of lung infection of CRAb in ICU were collected from our hospital during Jun. 2012 to Jun. 2014,with the 81 cases of CRAb and 24 cases of CSAb. RESULTS:The univariate analysis showed that those factors were significantly correlated with lung infection of CRAb in ICU,such as ICU hospitalization days be-fore isolation of Ab,total stay in ICU,respiratory failure,hypoproteinemia,mechanical ventilation,mechanical ventilation days, the application of carbapenem antimicrobial agents and combined use of antimicrobial agents within 15 days before isolation of Ab, abnormal C-reactive protein detection,abnormal procalcitonin detection. The multivariate analysis showed that ICU hospitalization days before isolation of Ab,the application of carbapenem antimicrobial agents within 15 days before isolation of Ab,mechanical ventilation,hypoproteinemia were the independent risk factors of CRAb. CONCLUSIONS:Based on risk factors,the measures should be taken for high-risk patients as soon as possible in ICU to prevent and treat lung infection of CRAb.
