chorioamnionitis

Pronunciation: KORE-ee-oh-am-nee-oh-NYE-tis

Infection of the fetal membranes and amniotic fluid, potentially causing maternal fever and fetal complications.

Full Definition

Chorioamnionitis is an acute inflammation of the chorion and amnion, the membranes surrounding the fetus, typically caused by bacterial infection. This condition can occur before or during labor and may present with maternal fever, uterine tenderness, foul-smelling amniotic fluid, and elevated maternal white blood cell count. Risk factors include prolonged rupture of membranes, prolonged labor, and multiple vaginal examinations. Chorioamnionitis poses risks to both mother and baby, including maternal sepsis, postpartum endometritis, neonatal sepsis, and increased risk of cerebral palsy in preterm infants.

Usage

Usage note: Sometimes abbreviated as chorio in informal clinical discussion, but use full term in documentation.
