When a couple decides to have a child, a man and a woman is often a question arises over whether they be compatible Rh blood.For quite a long time physicians and scientists are engaged in the study of these indicators.This article will tell you about what has Rh compatibility.You find out in which cases it is not necessary to worry about the fact that the formation of antibodies in the blood cells.It is also worth mentioning that a Rh-conflict pregnancy.
What rhesus human blood?
Rh blood - is the presence or absence of a certain protein in the membrane of red blood cells.In most cases it is present.That is why about 80 percent of the population are positive rhesus.About 15-20 percent of people become owners of negative blood.It is not certain pathology.Scientists in recent years, are talking about the fact that these people are special.
Rh factor: Compatibility
Quite a long time became known details about what kind of blood goes well, and no other types of it.To calculate the compatibility of Rhesus factor for conception, or for any other purpose, you must refer to the table.They are presented to your attention in this article.Depending on what you want to see the data on the compatibility may vary.Consider the cases in which recognizes the compatibility of Rh factors, and when not.
donation
Rh factor compatibility in the case of blood donation will be in the following cases.A man with a positive value (when the red blood cells present the so-called protein) can deliver the material for negative people.Such a blood transfusion to all recipients, regardless of whether they have Rh.
Rh factor compatibility does not give in when the donor gives a negative material for positive person.In this case, it may be a serious conflict cells.It is worth recalling that at the time of transfusion material should take into account the compatibility of blood group and Rh factor.That is what makes experienced professionals in the walls of medical institutions.
planning pregnancy
great importance is the compatibility of the Rh factors of parents of the future baby.Many couples mistakenly believe that these values depend on the probability of conception.Thus, long-term unexplained infertility man and a woman is blamed for blood group and Rh affiliation.This is absolutely wrong.
It does not matter whether there is a protein in the cells of the erythrocyte sexual partners.This fact does not affect the likelihood of fertilization.However, fertilization and establishment of the fact of pregnancy Rh (compatibility indicator of his father and mother) plays an important role.How do these values to the unborn child?
Compatible Rh
- If a man does not have a protein on cells of red blood cells, most often there is no danger.This woman may be positive or negative.This fact is not absolutely essential.
- When Rh positive women have given blood men of no particular significance.Pope future baby can have any performance analysis.
potential conflict
Compatibility Rh factors parents can be compromised when a woman is negative and positive man.At the same time it plays a big role, whose performance has acquired future baby.Currently, there are some studies of maternal blood.Their result may be up to 90 percent of the baby's blood to establish affiliation.Also during pregnancy to women with Rh-negative recommend blood tests to determine the presence of antibodies.This helps to prevent conflict and to hold it in time to prevent.
Rh factor: the conflict in pregnancy
during childbearing, many women are faced with different challenges.One of them is incompatible blood group and Rh factor.In fact, it does not matter what blood (group) in the expectant mother.Much greater importance is the presence or absence of the protein in the cells of the red blood cells of pregnant.
If a woman is Rh negative and a man (father of the unborn baby) is positive, then the conflict may develop.But this will happen only if the fetus has acquired property of her father's blood.
How to develop complications?
Supplies Blood baby is determined at the very beginning of pregnancy.At about 12 weeks the fetus develops independently through the action of progesterone.In the second half of pregnancy there is a continuous communication and mutual exchange of substances between mother and unborn baby.Blood woman and the fetus can not communicate with each other.However, through the umbilical cord baby gets all the nutrients and oxygen.Gives he unneeded components, which can be released and the red blood cells.Thus, the protein found in the blood cells, enters the body of the future mother.Her circulatory system does not know of this element, and treats it as a foreign body.
Because of this process, the body of a pregnant woman produces antibodies.They are aimed at the destruction of an unknown protein and neutralize its action.Since most of the substances from the mother to the fetus goes through the umbilical cord, the same method of antibodies into the body of the baby.
What threatens Rhesus conflict?
If a woman has been formed in the blood are the same antibodies that soon they can get to the fetus.Further substances begin to destroy them unknown protein and destroy normal red blood cells of the baby.The consequence of this may be many congenital diseases or fetal complications.
Most kids who have been Rhesus conflict with her mother, suffered jaundice.It is said that this complication is becoming one of the most innocuous.In the decay of red blood cells in the blood of bilirubin formed baby.It was he and causes yellowing of the skin and mucous membranes.
After giving birth to Rhesus conflict often found disease of the liver, heart and spleen.Pathology may be easy to correct, or be quite serious.It all depends on the duration of the destructive action of antibodies in the body of the child.
In rare cases, rhesus conflict during pregnancy can lead to the birth of dead children or fetal death.
What are the signs of complications?
Is it possible to learn something about the developing Rhesus conflict during pregnancy?In most cases, the pathology is detected by a blood test.Each expectant mother, having a rhesus negative values must regularly take material from a vein for the diagnosis.If the result showed the presence of antibodies in the body, the doctors are taking measures aimed at improving the status of the baby.
also suspect Rhesus conflict during pregnancy allows conventional ultrasound.If, during the diagnostic expert reveals increased size of organs such as the liver and spleen, you may develop a complication already in full force.Also, diagnosis may show swelling of the entire body of the child.This outcome occurs in more severe cases.
compensation of Rh-conflict pregnancy
After detecting the disease need to soberly assess the condition of the unborn child.In many ways, the scheme of treatment depends on the duration of pregnancy.
So, in the early stages (up to 32-34 weeks) used a blood transfusion at the woman.She was in the organism introduced new material, which has formed antibodies.It is detrimental to the child's blood is simply eliminated from the body.This scheme is usually carried out once a week until delivery possible.
In later pregnancy, it may be decided that an urgent caesarean section.After the correction of the birth of the child.In most cases, the treatment regimen includes the use of drugs, physical treatments, exposure to blue light, and so on.In more severe cases, a blood transfusion to the newborn.
Prevention Rh-conflict pregnancy
Can you somehow prevent the development of disease?Of course, yes.Currently, there is a medicine that fights formed antibodies.
If pregnancy first, then the probability of the development of Rh-conflict is minimal.Most often, the red blood cells do not mix.However, during birth occurs the inevitable formation of antibodies.That is why it is necessary to introduce an antidote for three days after the birth of a child with Rh positive from negative mother.Such action will avoid complications in future pregnancies.
What to do when the time came and missed the next birth?Is it possible to somehow protect the child from the conflict?Expectant mother in this case it is recommended to regularly monitor the condition of the blood by conventional assays.The above material is introduced into the body of a pregnant woman in the period of about 28 weeks.This allows you to make a baby to term without complications.
Summary
you now know, it looks like a table of compatibility of blood group and Rh factor.If you do not have that same protein on cells of red blood cells, you should be sure to inform your doctor.During pregnancy, for your well-being and behavior of the fetus will be a special control.This will avoid Rh-conflict or in a timely manner to make its prevention.I wish you health!
