Abstract: Objective To evaluate the clinical characters of neonatal sepsis in term and preterm newborns for early diagnosis and treatment. Method A retrospective study was done to collect clinical characteristics and drug sensitivity in term and preterm neonatal sepsis from January 2009 to May 2011 in neonatal care unit. Results Preterm newborns had higher risks for the incidences of premature rupture of membranes and intravenous nutrition.Preterm newborns were susceptible to hyperbilirubinemia,respiratory distress syndrome,feeding intolerance and neonatal asphyxia,while term newborns were susceptible to omphalitis.G⁺ bacteria was the major pathogen in neonatal sepsis with higher incidence rate in term newborn.Candida albicans infection was susceptible to preterm newborns. Conclusion Preterm newborns with septicemia need more invasive operation to be susceptible to complex complications and complicated with fungal infection.
