RESUMEN
OBJECTIVE To investigate pathogens in neonatal septicemia and the antimicrobial resistance of these bacteria in recent years to guide the clinical treatment.METHODS The data of 76 neonatal septicemia confirmed by hemoculture from Jan 2005 to Jan 2008 in our hospital were analyzed retrospectively.RESULTS Coagulase-negative Staphylococcus(CNS) were the main pathogens,among which their were 47.36% of S.epidermidis,10.53% of S.haemolyticus,9.21% of S.aureus,and the others of 7.88% Escherichia coli.Bacteria were highly resistant to penicillin,ampicillin and erythromycin.Vancomycin,imipenem,ciprofloxacin and amikacin were the most sensitive drugs.CONCLUSIONS Gram-positive cocci are main pathogens in neonatal septicemia,in which the CNS are the most common ones.To choose sensitive antibiotics bases on the drug sensitivity tests may decrease the occurrence of drug resistance to bacteria and increase the clinical curative effects.
