ANALYSIS OF POSITIVE BACTERIAL BLOOD CULTURE OF 49 TUMOR PATIENTS

Objective To investigate blood culture positive pathogens distribution and predisposing factors from tumor patients in hospital and to provide the guidance for the prevention of bloodstream infection and rational drug use in clinic.Methods Retrospective investigation was used to investigate and analyze pathogens of the positive blood culture from 49cases. Results 70 strains of pathogenic bacteria were isolated from blood culture samples of 49 patients,including 40strains of Gram- negative bacteria( 57. 14%),25 Gram- positive strains( 35. 71%),5 strains of fungi( 7. 14%). 23cases were pure bloodstream infection which accounting for 46. 94%,homologous infection bacteria were detected from sputum or urine specimens from the remaining 26 cases. Gram- negative and Gram- positive bacteria were Escherichia coli and Staphylococcus which resistant to most antibiotics and sensitive to vancomycin and imipenem. Conclusion Patients with bloodstream infection accounted for only 46. 94% among those with positive blood culture in hospital,the main pathogens were gram- positive bacteria which had general drug resistance.
