本文对我院7年来106例双胎中7例孕中、晚期一胎宫内死亡的病例进行了分析,单绒毛膜双胎一胎死亡的危险性比双绒毛膜高4.6倍。主要死因与双胎输血综合征、妊高征、畸形、脐带因素有关。双胎之一宫内死亡后对母体影响不大,对存活儿的影响,主要是早产带来的危险。对单绒毛膜双胎有双胎输血综合征的存活儿影响较大。处理:如胎龄小,胎儿不成熟,应保守治疗。如胎肺成熟应及时终止妊娠。在双胎之一宫内死亡前,加强产前检查,积极防治妊高征。早期发现双胎输血综合征并给予积极治疗,是提高双胎生存率的关键。
In this paper, 7 cases of our hospital in 106 cases of twins in 7 cases of second trimester of fetal death in the analysis of intrauterine fetal death of single chorionic twins than the double chorion of 4.6 times. The main cause of death and twin fetal syndrome, PIH, deformity, umbilical cord factors. One of the twins after the intrauterine death of the mother had little effect on the survival of children, mainly due to the risk of premature birth. The single chorionic twin twins have a greater impact on the survival of survivors. Treatment: such as small gestational age, immature fetus should be conservative treatment. Such as fetal lung maturity should be terminated in time. Before the death of one of the twins in the womb, strengthen prenatal care, and actively prevent pregnancy-induced hypertension. Early detection of twin blood transfusion syndrome and give active treatment, is to improve the twin survival rate of the key.
