Comparisons on clinical manifestation and pathogen spectrum of sepsis between full-term and premature ;neonates of 38 cases / 实用医学杂志

ABSTRACT

Objective To investigate the clinical manifestations and pathogen distribution of the neonatal sepsis, and to analyze the antibiotic resistance of the pathogens. Methods Review the Medical records of 38 sepsis cases of full-term and premature neonates in our hospital from October 2011 to February 2014 were col-lected and analyzed. Results Ten cases were caused by Gram-positive bacteria among the 18 full-term neonates with sepsis. Eight of ten of the isolates were resistant to oxcillin. Nine of ten of the cases were belonged to late onset infection, and the cases with no nosocomial infection were found. In the other eight full-term neonatal cases caused by Gram-negative bacteria , six cases were nosocomial infection. Among the 20 premature neonates with sepsis , 17 cases were infected Gram-negative bacteria , in which Escherichia coli , Klebsiella pneumonia and En-terobacter cloacae were the most common agents (16/17). Early onset type and nosocomial infection were identi-fied for 11 (11/20) and 9 (9/20) cases in the premature neonates, respectively. The penicillin G, methicillin resistant rates of the Gram-positive bacteria were close to or over 70%. All the Gram-positive bacteria were sensi-tive to vancomycin. All the Gram-negative bacteria were resistant to amoxicillin , but over 60% of them were sen-sitive to piperacillin-tazobactam and other compounds containing enzyme inhibitor , and 100% of them were sensi-tive to carbapenems and aminoglycoside. Conclusion The full-term neonatal sepsis admitted into our hospital were mainly caused by Gram-positive bacteria , which were usually resistant to oxcillin. The premature sepsis were mainly caused by Gram-negative bacteria , which were always sensitive to carbapenems and aminoglycoside.
