Panda blood to avoid hemolysis should pay attention to the following points: should avoid blind abortion, good pre-pregnancy preparation, regular pregnancy monitoring. 1. Avoid blind abortion: the embryo’s RH antigen has matured on the 32nd day of pregnancy, and fetal blood can enter the mother’s bloodstream during abortion, resulting in maternal sensitization and increasing the risk of hemolytic disease of the fetus when pregnant again, and the risk increases gradually with the increase in gestational weeks. 2. Make good preparation before pregnancy: if it is the first pregnancy, it is recommended to have regular blood immunology examination from the fifth month of pregnancy, and mothers-to-be who have had hemolytic disease of the newborn in the past are not recommended to get pregnant in a short period of time because of the high IgG antibody in the blood. If necessary, oral antibody immunosuppressants and plasma exchange can be used to minimize the antibody potency in the body before preparing for pregnancy. 3. Regular pregnancy monitoring: RH-negative pregnant women should undergo blood type, antibody screening and antibody potency testing, and regular monitoring of antibody potency; for non-sensitized pregnant women, the first test should be carried out in the 16th week of pregnancy, and once a month thereafter; for sensitized pregnant women, the test should be carried out once a month when the antibody potency is lower than the threshold value, once every two weeks after the 24th week of pregnancy, and once a week when it exceeds the threshold value. If the antibody potency reaches or exceeds 1:128 in the course of regular monitoring, timely hospital consultation should be made and treatment should be carried out under the guidance of professional doctors to reduce the risk of hemolysis in newborns.
