从测定羊水血型物质来预测胎儿血型国内有所报道。我院在开展胎产儿因母子血型不合引也的免疫性溶血病的诊治过程中,觉得通过羊水预测胎儿血型,对ABO系统新生儿溶血病在孕期就能确定诊断并及时治疗。当母子血型相同或胎儿为O型的孕妇可避免不必要的或盲目的孕期治疗,对Rh新生儿溶血病则能在产前预知胎儿血型,可提前为换血作好血源准备。 From the determination of amniotic fluid blood group to predict fetal blood type has been reported in the country. In our hospital, we found out that fetus blood type was predicted by amniotic fluid in the process of diagnosis and treatment of immune hemolytic disease due to maternal and child blood group incompatibility. We can confirm the diagnosis and timely treatment of neonatal hemolytic disease of ABO system during pregnancy. When pregnant women with the same mother or child’s blood type or O-fetus can avoid unnecessary or blind pregnancy treatment, the blood type of fetus can be predicted in prenatal period for Rh neonatal hemolytic disease, which can prepare blood for blood exchange in advance.
