Abstract

An increased placental ratio has known to be associated with the occurrence of cardiovascular complications in adulthood among the intrauterine fetal growth restriction. A retrospective study on 202 singleton growth-restricted infants without major congenital anomalies born from Jan. 1995 to Feb. 2001 was performed to determine the relationship between placental ratio and neonatal morbidity. The cases were categorized into three groups according to the placental ratio (<1SD below the mean, within 1SD of the mean, >1SD above the mean). There were no differences in the maternal characteristics and antenatal complications except pregnancy induced hypertension between high placental ratio group and the other groups. It presented the trend that was toward the increase of placental weight and the decrease of birth weight in high placental ratio group. The infants with a high placental ratio had increasing tendencies of meconium stained amnionic fluid, hypocalcemia, phototherapy, asphyxia.
