母婴血型不合引发的反复流产Miscarriage caused by maternal and infant blood type differences

母婴血型不合，诊断依据是：母亲是O型血，丈夫是其他血型，以往妊娠或输血，流产多发生在孕7个月后，胎儿水肿。

The diagnosis of maternal and infant blood types is based on: the mother is O-type blood, the husband is other blood types, past pregnancy or blood transfusion, miscarriage occurs more than 7 months after pregnancy, fetal edema.

母婴血型不合流产的原因是胎儿的Rh因子、不合的ABO血型因子在母体中产生抗体，此次妊娠由胎盘进入胎儿体内与红细胞凝集而产生溶血，以致流产。

The reason why maternal and infant blood types do not match causes miscarriage is that the fetus's Rh factor and the incompatible ABO blood factor produce antibodies in the mother's body. This pregnancy enters the fetus from the placenta and condenses with red blood cells to produce hemolytic blood, resulting in miscarriage.

陈凤林教授指出：母婴血型不合流产理想的治疗是孕前进行免疫治疗，治愈率达90%;如果是孕中确诊可以在 胎儿存活的前提下剖腹产，然后对婴儿进行换血处理，保全孩子性命。

Professor Chenfenglin pointed out: The ideal treatment for maternal and infant blood type miscarriages is immunization before conception, and the cure rate is 90 %; If it is diagnosed in pregnancy, Caesarean section can be performed on the premise of the fetus's survival, and then the baby is changed to save the child's life.
