Early versus late onset neonatal septicemia at Children's Hospital.

ABSTRACT

An analysis was made of 695 cases of neonatal sepsis at Children's Hospital from 1982 to 1986. The incidence of neonatal sepsis and septicemia were 6.5 and 2.4 per 1,000 livebirths respectively. There were 178 cases of septicemia with onset during the first four days of life (early onset group) and 77 cases with onset after four days of life (late onset group). Both groups did not differ significantly in sex, birth weight and gestational age. Most of the cases had low birth weight and were premature. Pneumonia was the common associated infection. Omphalitis was found more frequently in the early onset of septicemia, whereas, NEC and skin infection were found more in the late onset group. Pseudomonas aeruginosa and Klebsiella pneumoniae were the major causes of infection in both groups. Staphylococcus was more common in late septicemia. No statistical difference in major complications was found between the two groups. Fatality rate in early and late septicemia was 32.6 and 28.2 per cent respectively.
