概述

一次妊娠宫腔内同时有两个或两个以上胎儿时称为多胎妊娠(multiple pregnancy),以双胎妊娠多见。近年来随着辅助生殖技术广泛开展,多胎妊娠发生率明显增高,可引起妊娠高血压疾病、贫血多胎妊娠属于高危妊娠,应加强妊娠期及分娩期管理。绒毛膜性对多胎围产儿预后的影响比合子性更大,应在妊娠早期进行多胎妊娠的绒毛膜性的判断。双胎输血综合征和选择性生长受限是羊绒毛膜性双胎特有的严重并发症。 双胎类型及特点1)双卵双胎:两个卵子分别受精形成的双胎妊娠,称为双卵双胎(dizygotic

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.

多胎妊娠与流产风险增加、早产、胎膜早破和早产有关。美国国家生命统计数据显示,单胎妊娠的早产率为8.1%,双胎妊娠的早产率为59.4%。36%的双胎妊娠和28%的三胎妊娠可在28周前发生胎膜早破。在妊娠34周之前,大约20%的双胞胎和68%的三胎妊娠分娩。围产儿发病率和死亡率与早产孕龄呈负相关。胎儿的总体结局也非常依赖于指定的绒毛膜,但这些数据很少被前瞻性地定义。这些早产儿有呼吸窘迫综合征、早产儿慢性肺病、早产儿视网膜病变、坏死性小肠结肠炎、显著的脑室内出血、败血症、脑瘫、运动和感觉障碍、学习困难和慢性疾病风险增加的危险。据估计,仅在美国,早产的社会成本每年就高达260亿美元。
