Midtrimester amniocentesis: obstetric outcome and neonatal neurobehavioral status.
The possible effects of midtrimester genetic amniocentesis on neurobehavioral status were studied in newborn infants of women who had had the procedure (N = 100) and in newborn infants of women who had declined the test (N = 56). Brazelton's Neonatal Behavioral Assessment Scale was administered to newborn infants born at term and did not reveal consequences of amniocentesis on neonatal orientation, range of state, motor ability, autonomic regulation, regulation of state, response decrement, or reflexes. Information on obstetric complications also was obtained. The findings raised questions regarding the temporal relationship between amniocentesis and fetal loss and focused attention on preterm birth as a potential risk that warrants further investigation. This study provides the foundation for our prospective longitudinal follow-up in which the cohort will be reassessed later in infancy and in childhood.
