Compared with singleton pregnancies, triplet pregnancies are associated with a significantly increased risk of adverse pregnancy outcomes. Early ultrasound examination is the best way to diagnose triplets, establish dating, and determine the number of placentas to provide appropriate counseling and monitoring. Dichorionic placentation adds risks specifically associated with a shared placenta, and limits options for intervention. Multifetal reduction is an option that can significantly improve pregnancy outcomes compared with non-reduced triplet pregnancies. Integration of a Maternal-Fetal Medicine specialist in the prenatal care for a triplet pregnancy reduces the risk of preeclampsia, preterm birth, low birthweight infants, perinatal mortality, and major neonatal morbidity.
与单胎妊娠相比，三胎妊娠发生不良妊娠结局的风险显著增加。早期超声检查是诊断三胎妊娠、确定胎龄和确定胎盘数量的最佳方法，可提供适当的咨询和监测。双绒毛膜胎盘增加了与胎盘共享相关的特定风险，并限制了干预的选择。多胎减少是一种选择，与未减少的三胎妊娠相比，可以显著改善妊娠结局。将母体胎儿医学专家纳入三胎妊娠的产前护理中，可以降低子痫前期、早产、低出生体重儿、围产儿死亡率和主要新生儿发病率的风险。
