Abstract: ObjectiveTo investigate the risk factors and pathogenic characteristics of catheterrelated infection (CRI) in intensive care unit (ICU),so as to find a better way for its treatment.Methods Retrospective analysis was performed on 247 deep-venous catheter (DVC) from January 2007 to December 2010.ResultsAmong 247 patients,positive results of 41 patients diagnosed CRI,negative results of 206 patients undiagnosed CRI.Compared with undiagnosed CRI patients,found the correlation of the underlying infectious diseases,indwelling time of catheter and puncture sites associated with CRI occurred(P ＜ 0.05 ).CRI major pathogen was gram-positive bacteria (58.5％,24/41 ),in which Staphylococcus epidermis was the major pathogenic bacteria(22.0％,9/41).The drug resistance occurred in most pathogen.Conclusions The occurrence of CRI is related with multiple clinical factors.The gram-positive bacteria is the major pathogen.The etiological monitor should be enforced in patients with DVC.
