Neonatal sepsis
Alternate Names : Sepsis neonatorum, Neonatal septicemia, Sepsis - infant
Definition
Neonatal sepsis is a blood infection that occurs in an infant younger than 90 days old. Early-onset sepsis is seen in the first week of life. Late-onset sepsis occurs between days 8 and 89.
Overview, Causes, & Risk Factors
A number of different bacteria, including Escherichia coli (E.coli), Listeria, and certain strains of streptococcus, may cause neonatal sepsis. Early-onset neonatal sepsis most often appears within 24 hours of birth. The baby gets the infection from the mother before or during delivery. The following increases an infant's risk of early-onset sepsis:
- Group B streptococcus (group b strep) infection during pregnancy
- Preterm delivery
- Rupture of membranes (placenta tissue) that lasts longer than 24 hours
- Infection of the placenta tissues and amniotic fluid (chorioamnionitis)
Babies with late-onset neonatal sepsis get infected after delivery. The following increase an infant's risk of sepsis after delivery: - Having a catheter in a blood vessel for a long time
- Staying in the hospital for an extended period of time
