Needle aspiration and analysis of amniotic fluid (amniocentesis) is the only invasive procedure used to confirm the diagnosis of acute chorioamnionitis. This procedure can be risky with intact fetal membranes, because the fetal membranes can rupture during or after the procedure. Bleeding or placental abruption can also be a consequence of amniocentesis. The procedure should be performed using ultrasonographic guidance to avoid fetal injury. For these reasons, amniocentesis to diagnose maternal chorioamnionitis has had limited application in obstetric practice.
