Abstract:
OBJECTIVE To study the epidemiology and the sensitivity to antibiotics of bacteremia in intensive care unit,and provide the reference for the clinical antimicrobial agents usage. METHODS 465 cases of bacteremia from Jan 2005 to Dec 2007 in the First Affiliated Hospital,Medical College of Zhejiang University were retrospectively analyzed. RESULTS Totally 1465 strains of pathogens were isolated in three years,and the positive rates were 22.6%.From them 155 strains were fungi(10.6%),611 strains were Gram-positive bacteria(57.9%) and 392 strains were Gram-negative bacteria(37.1%).G + strains mainly included coagulase-negative Staphylococcus(CNS,43.0%) and Staphylococcus aureus(2.1%);the sensitive antibiotics were vancomycin and teicoplanin.G-strains mainly included Acinetobacter baumannii(8.6%);Stenotrophomonas maltophilia(6.6%);Pseudomonas(5.1%) and Klebsiella pneumoniae(5.3%),the sensitive antibiotics were cefoperazone/sulbactam. CONCLUSIONS The positive rates of blood culture are higher in intensive care unit than in others.We should pay more attention to CNS for its high infection rate.The sensitive antibiotics of G + are vancomycin and teicoplanin.The sensitive antibiotics of G-are cefoperazone/sulbactum.Antimicrobial therapy should be conducted according to susceptibility test.The candidemia caused by non-Candida albicans(NCA) is increaseing in recent 3 year.
