Abstract:
Objective To study the characteristic of etiology and drug resistance of neonatal sepsis for rational use antibiotics in clinic.Methods The etiology and drug resistance of 167 positive hemoculture examples of 365 neonatal sepsis examples were retrospectively analyzed,and the characteristic of etiology diversify and drug resist-ance characteristic of neonatal sepsis were also analyzed.Results In 365 blood culture examples of neonatal sepsis, there were 167 positive cases,positive ratio was 45.75%.Among pathogenic bacterium,the first etiology was staphylo-coccus epidermidis,there were fifty -eight examples and account of 34.73%.The second was staphylococcus haemo-lyticus and accounts twenty -nine examples and 17.37%.The third was staphylococcus aureus which had twenty -two examples and account 13.17%.The annual infection rate of staphylococcus epidermidis and staphylococcus hae-molyticus in the second five years were increased obviously.Gram -positive coccus drug resistance to penicillin,cep-hazolin,oxazocilline and cefoxitin were very high and the rate of the second five years were higher than that of the first five years.Gram -positive coccus drug resistance to third -generation cephaloporins and imipenem and meropenem were higher than vancocin and the rate of the second five years were higher than that of the first five years.Gram -positive coccus was 100.00% sensitive to vancomycin.Gram negative bacilli drug resistance rate to penbritin and cep-hazolin and third -generation cephaloporins was the highest.Gram negative bacilli to meropenem and imipenem was hypersensitive in all antibiotics.Conclusion The chief pathogenic bacteria of neonatal septicemia is staphylococci. Among pathogenic bacterium,the main pathogenic bacteria is CoNS,and staphylococcus epidermidis and staphylococ-cus haemolyticus goes up significantly.Among gram -negative bacilli,the escherichia coli goes up.The drug resist-ance to bacteria goes up in neonatal sepsis,it is very important to monitor the drug resistance.
