近年来由于围产医学的发展以及产科技术的进步,围产儿病死率已明显下降,但双胎的围产儿病死率依然较高,约为150%左右。因此如何处理多胎妊娠,降低其围产儿病死率己成为产科工作者面临的重要课题之一。导致双胎妊娠围产儿死亡的因素甚多,关系较为密切的有重度妊高征、羊水过多、贫血、胎膜早破、早产、前置胎盘、胎盘早期剥离及胎位异常等。由于多胎妊娠胎儿相对较小,产道性难产已很少见,对母儿的主要威胁来自孕产期并发症和胎位异常。因此,降低围产儿病死率除必须加强围产期监护、预防早产外,实行计划分娩、恰当地选择分娩方式,也是
In recent years, due to the development of perinatal medicine and advances in obstetrics and technology, perinatal mortality has dropped significantly, but the perinatal mortality of twins is still high, about 150%. Therefore, how to deal with multiple pregnancy and reduce perinatal mortality has become an important issue facing the obstetric workers. There are many factors that lead to the death of perinatal twin mothers. There are many related factors such as severe pregnancy-induced hypertension, polyhydramnios, anemia, premature rupture of membranes, premature labor, placenta previa, placental abruption and abnormal fetal position. Due to the relatively small number of fetuses with multiple pregnancies, obstetric dystocia is rare, and the main threats to mothers and fathers are from maternal complications and fetal abnormalities. Therefore, to reduce perinatal mortality in addition to the need to strengthen perinatal care, prevent preterm birth, the planned delivery, the proper choice of mode of delivery, but also
