Multiple pregnancy is associated with an increased risk of miscarriage; premature, preterm rupture of membranes, and preterm birth. Data from the United States National Vital Statistics revealed the rate of preterm birth was 8.1% in singleton pregnancy and 59.4% in twin pregnancy. Thirty-six percent of twin and 28% of triplet pregnancy could be complicated by preterm premature rupture of membranes before 28 weeks of gestations. Approximately 20% of twin and 68% of triplet pregnancy delivered before 34 weeks of gestation. The risk of perinatal morbidity and mortality was inversely correlated to the gestational age of preterm birth. The overall outcome for the fetuses is also very dependent on assigned chorionicity, but these data are rarely defifined prospectively. These preterm neonates are at risk of respiratory distress syndrome, chronic lung disease of prematurity, retinopathy of prematurity, necrotizing enterocolitis, signifificant intraventricular hemorrhage, sepsis, cerebral palsy, motor and sensory impairment, learning diffificulties, and increased risks of chronic diseases. It is estimated that the societal cost of preterm birth was $26 billion annually in the United States alone.
