Chorioamnionitis is infection of the amniotic fluid, membranes, placenta, and/or decidua.
It is a major risk factor for neonatal sepsis.
Diagnosis is sometimes made by the presence of maternal fever alone, but for research purposes is defined by the presence of maternal fever >38oC and >1 of the following:
- maternal leukocytosis (>15)
- maternal tachycardia (>100bpm)
- uterine tenderness
- fetal tachycardia (>160bpm)
- foul odour of amniotic fluid
