Chorioamnionitis: implications for the neonate

Clin Perinatol. 2015 Mar;42(1):155-65, ix. doi: 10.1016/j.clp.2014.10.011. Epub 2014 Nov 21.

Abstract

Chorioamnionitis (CA) is characterized by inflammation of the fetal membranes. The incidence increases with decreasing gestational age at birth. When suspected on clinical criteria, pathologic assessment of the placenta should be performed. Although the mechanisms are not entirely clear, CA predisposes to premature birth, neonatal sepsis, and intraventricular hemorrhage. Its role in respiratory distress syndrome, bronchopulmonary dysplasia, and neurodevelopmental impairment is mixed. Prevention and treatment are ill-defined; antibiotics for preterm premature rupture of membranes reduce the incidence and increase the length of time to delivery. Antibiotics are recommended for infants exposed to CA while laboratory studies are being performed.

Keywords: Fetal inflammatory response; Mycoplasma; Neonatal sepsis.
