Which blood type combination may be a threat to conception

In terms of blood type, which combination of blood types may be a threat to conception? We need to pay attention to the following points:

1. The couple should go to a qualified hospital or blood station to check their blood type. If your husband is type A, B or AB, and you are type O, you may have an ABO blood type incompatibility when you are pregnant ; if your husband is RH positive and you are RH negative, you may have an RH blood type incompatibility. However, even if the couple's blood types are incompatible, there are still a small number of fetal hemolytic diseases and even stillbirths. For RH-negative pregnant women , the chance of fetal hemolytic disease is only 1/20. But regardless of the possibility, it should be further checked.

2. Determine antibody titer during pregnancy. 28 weeks after you are pregnant again, the measurement will be performed every 2 weeks. After 32 weeks, the RH or ABO blood group incompatibility antibody titer will be measured once every 1 week. .

3. Amniotic fluid examination. Because the antibody titer is only 60% correct to evaluate the condition, it is possible to draw amniotic fluid after 36 weeks of pregnancy to agree on the bilirubin content, to further determine the condition, and to decide the choice of treatment measures.

4. If the diagnosis is maternal and child blood type incompatibility, conservative treatment can be used first, including: oral vitamin E; agent until delivery); to 24 weeks of pregnancy, 30 weeks and 33 weeks of each 10-day comprehensive treatment, daily intravenous injection of 25% glucose sugar 40 ml vitamin C 1 g; 3 times a day oxygen; two weeks before the expected date Started oral phenobarbital 30 mg, 3 times a day. These all help strengthen the fetal resistance.

5. The closer to term, the more antibodies are produced, and the greater the harm to the fetus. Therefore, induction of labor may be considered based on specific circumstances after 36 weeks of pregnancy.

6. All pregnant women diagnosed with mother-child blood type incompatibility should be hospitalized as soon as possible to prepare for labor induction or delivery, because the newborn needs a series of rescue and treatment after delivery.
