Abstract: Clinical data of 116 patients with implanted permanent dual catheters for hemodialysis,including 18 with infection and 98 non-infection, during January 2006 and July 2009 were retrospectively analyzed to study risk factors for catheter-related bacteremia (CRB). Duration of catheter implantation,primary disease, routine blood examinations and blood biochemical examination of the patients were analyzed between the two groups. COX proportional hazard regression analysis was performed for all predictor variables. Results showed that overall incidence of bacteremic episodes was 0. 314 per 1000 catheter-day.Compared to that in infection group, levels of hemoglobin, plasma albumin, peripheral lymphocyte count and ratio of CD4/CD8 in non-infection group were significantly higher ( all P ＜ 0. 05 ), and OR of CRB were 4. 011 (P =0. 0213) for diabetes mellitus and 7. 181 for hemoglobin level less than 80g/L (P = 0. 0020),respectively. It is suggested that improving nutrition status and correcting anemia for patients with hemodialysis are necessary to reduce CRB.
