The fact that there is this factor or not, it does not affect human health in any way. What is it for, why does the blood of pregnant women take on Rh-belonging? Yes, because the spouses (partners) are completely healthy, can have different Rh factors. For example, in the father of a child, the Rh factor is positive, and the mother is Rh-negative. And the future child can inherit his father's rhesus, and this will be incompatible with the maternal rhesus.
During pregnancy, the red blood cells of the fetus can penetrate the mother's blood, for the body this antigen will be foreign and it will start producing antibodies. And having penetrated from the mother to the fetus, they will destroy his erythrocytes. This can entail either a serious illness or fetal death, but not always, with the first pregnancy of antibodies not so much in the blood of the mother. But with subsequent pregnancies, the number of antibodies will grow, and it will not depend on whether the delivery was or the pregnancy was interrupted. Because of this, and the threat to the fetus increases, so that with negative Rhesus abortion is undesirable. Pregnant women should regularly visit a women's consultation and be tested for antibodies and if there is a need to undergo treatment. First, a woman is examined for sensitization - the presence of antibodies in the blood. It rises with blood transfusions of the positive Rh factor in the blood with negative rhesus, with abortion, ectopic pregnancy (7-8 weeks), miscarriage, chorion biopsy (on the fetal membrane), trauma in the pregnant woman. It can also appear before birth, if the Rhesus-negative girl got red blood cells of a mother with a Rh-positive factor. Doctors know how to take measures to ensure that women with negative Rhesus factor have healthy children. But all the same, with a negative Rhesus factor, abortion is very risky, so what's the reason, let's try to figure it out.
1. If the pregnant woman and the father of the Rh child have negative factors, they are worried, it is not necessary, the child will have a negative rhesus of both parents, Rhesus - there will be no conflict. The abortion will have a normal degree of risk.
2. If a woman has a negative Rhesus, and a positive male, in this case the fetus can inherit the positive Rh factor of the father. Then there will be a Rhesus conflict - in the body, women begin to develop antibodies, they penetrate the fetal blood through the mother's placenta and "attack" the erythrocytes, trying to destroy them. As a result, both the child and the mother suffer. As a result of the loss of erythrocytes in the fetus, the development of erythrocyte production begins, because of this, the spleen and liver increase. Erythrocytes perish, and oxygen starvation begins in the brain. Currently, doctors have found methods to combat this problem. A woman with a negative Rh factor and a child with a positive Rh factor are observed, examined and, if necessary, are treated in a special way to stop the Rhesus-conflict. Keeping the "peaceful" position until the end of the pregnancy. But during childbirth, there may be a risk of getting fetal blood into the mother's blood. If such a situation happens, the body will start producing antigens. It is important to observe for the first time months after childbirth.
Negative Rh factor, abortion - risk of infertility.
Negative Rh factor, abortion - the risk of infertility in this case increases many times. It does not depend on what method abortion is performed: surgical or medicamentous, abortion will not pass without a trace. And the danger is not only in this, at the first rhesus-conflict, in the body the woman starts to develop antigens, they are larger than other cells, inactive, penetrate through the placenta with difficulties. For this reason, during the first pregnancy there is a threat of miscarriage, more often than in women without Rh-conflict. The signal was received by the body and in subsequent pregnancies, immediately the development of antigens ready to "rush into battle" will begin. But they will be ready for battle and become much smaller, more mobile and capable of inflicting more powerful blow to the enemy (red blood cells of the fetus). Thus, at every subsequent rhesus-conflict pregnancy, the risk of miscarriage or pathology in fetal development increases. And regardless of whether the child was born or had an abortion, the risk level is increasing. Each pregnancy, miscarriage or abortion raises the risk by 10%. And at some point during the onset of pregnancy there will be a threat to the life of the mother and there will be virtually no chance of a favorable outcome.
Safety measures with a negative Rh factor.
It is not always the woman who chooses to abort the decision. There are cases when retention of pregnancy will lead to a danger or threat to the life of a woman.
To protect yourself and the fetus, a woman with negative Rhesus needs to know: the lower risk for abortion will be if it passes before the seventh week of pregnancy. Because the body starts producing antibodies, starting from the seventh - the eighth week from conception.
After abortion, it is necessary to introduce an antiresusive immunoglobulin, it is obtained from donor blood, and it is capable of stopping the production of antibodies. This procedure is carried out within three days from the day of abortion. It is especially important to carry out this procedure after the abortion of the first pregnancy, in order to reduce the risk in subsequent pregnancies.
There are no safe abortions, no maternal positive or no negative. Especially dangerous is abortion with negative Rhesus, it causes serious damage to health, even with good tolerability, the consequences may not immediately make you aware of yourself.
If all the same abortion is inevitable, you need to help your body recover and make minimal consequences.
