Abstract

The aim of the present study was to evaluate the effects of antibiotics on the condition of babies born with risk of neonatal sepsis. From March, 2014 to February, 2015, 200 neonates born with risk factors of septicemia in the Neonatal Intensive Care Unit at Xuzhou Central Hospital, were enrolled in the present study. Venous blood samples were collected within 6 h of birth using aseptic technique. Part of the blood specimens were cultured using BACTEC PEDS PLUS/F Culture Vials. Subsequently, the subcultures were prepared from each presumptive positive vial and bacterial isolates were identified. The remaining portion was used to measure the level of C‑reactive protein (CRP) and total leukocyte count (TLC). The result showed that 32% of neonates were infected, of whom, 21.9% had Staphylococcus aureus, 21.9% had Acinetobacter Baumanni, and 12.5% had Klebsiella pneumoniae. Additionally, Staphylococcus epidermis, Enteroccus spp., Pseudomonas aeruginosa and E. coli was isolated from 9.4, 7.8, 6.3 and 4.7% of neonates, respectively. The neonates enrolled in the present study had ≥1 risk factor for neonatal sepsis, and the average number of risk factors was 1.95 per neonate. Neonates (39.1%) with positive blood culture results, had a CRP level >0.8 mg/dl, and 12.5% was shown to have an abnormal increase in their leukocyte counts. The association between leukocyte counts and blood culture results was not statistically significant. Of the neonates with positive blood cultures 45.3% died within 7 days after birth, while there was no mortality among those with negative culture results. The results indicate that in the presence of risk factors for sepsis, irrespective of clinical features of septicemia, neonatal sepsis screening should be performed. Rational and appropriate use of antibiotics may minimize the emergence of multidrug resistant bacteria in neonatal units.
