Amniocentesis for fetal lung maturity: will it become obsolete?

AMNIOCENTESIS FOR FETAL LUNG MATURITY HAS HISTORICALLY BEEN PERFORMED FOR MANY REASONS: uterine and placental complications, maternal comorbidities, fetal issues, and even obstetric problems. Even though the risks associated with third trimester amniocentesis are extremely low, complications have been documented, including preterm labor, placental abruptions, intrauterine rupture, maternal sepsis, fetal heart rate abnormalities, and fetal-maternal hemorrhage. This review presents the types of tests for fetal lung maturity, presents the indications and tests utilized, and discusses recommendations for when amniocentesis for fetal lung maturity may be appropriate.
