title: Failure of determination of fetal lung maturation due to false-negative lecithin/sphingomyelin ratio in a case of pierre robin syndrome.
abstract: A case is reported of a baby with Pierre Robin syndrome born at term with adequate lung maturity. The evaluation of fetal lung maturity before birth by means of the lecithin/sphingomyelin ratio and foam test in the amniotic fluid revealed immaturity of the lungs. Examination of the tracheal aspirate following delivery, however, showed adequate lung maturity in the neonate.
