Dan Dan is a girl with polycystic ovary syndrome who finally became pregnant after weight loss, mood adjustment, endocrine and ovulation induction treatment. After pregnancy, it became a glass heart, what to eat, what to wear, what to check, you have to consult a doctor before you dare to act. Today to build a card, the examination is O type blood, suddenly nervous, worried that the baby will have hemolysis, inevitably another science popularization.
In fact, many women with blood type O in the clinic will worry about the existence of hemolysis after pregnancy, in fact, everyone is more worried.
If the woman is O blood and the man is also O blood, then there is no hemolysis. If the man is type A, B or AB, then the baby may be type A or type B blood, and hemolysis may occur at this time.
However, in general, the probability of hemolysis of ABO in the intrauterine blood group system is very small, and even if hemolysis occurs, it will not be very serious.
Therefore, women with blood type O do not have to worry too much about whether there is intrauterine hemolysis of the fetus. Many years ago, when we had preconception or obstetric tests, we routinely checked the blood group antibody titer. A large number of clinical data prove that antibody titer testing is meaningless as long as it is rh-positive blood type, because ABO intrauterine hemolysis is too rare.
So now the antibody test during pregnancy, that is, the test related to hemolysis, is no longer used as a routine test during pregnancy. Even if the blood group antibody potency is high, it simply means that the likelihood of hemolytic jaundice after the fetus is born will increase. There is generally no special treatment during pregnancy.
If the mother is blood type O, the jaundice index of the newborn increases rapidly 2-3 days after birth, the time of jaundice is early, the degree of jaundice is heavy, accompanied by pallor or severe skin and scleral yellowing, it is necessary to test the child's blood routine and blood type in time, and check the reticulocytes to determine whether there is ABO hemolysis. However, parents do not need to worry too much, most children do not need special treatment, only need to undergo medication and blue light irradiation, the prognosis is better.
