Rhesus Blood Factor and Rh-Conflict
Each of us, for sure, heard about such a concept as the Rh factor of blood. But what is behind these words? Let's try to figure it out.
The Rh factor of blood is a protein thatis located on the surface of erythrocytes. If the protein "floats up", the Rh is put positive and vice versa, if the protein on the surface is not found, the result is negative.
Statistics say that only one in sevenpart of the world's population has a negative Rh factor. The rest is positive. Studies are carried out, determining both the rhesus and the blood group simultaneously, although one does not depend on the other. The value of Rh-attribution is inherited. Can the Rh factor be changed? No, its meaning remains the same throughout his life.
When the baby is in the wombto establish its Rh-belonging exactly. Only less than ten percent of pregnant women have different rhesus factors with the fetus. And only less than one percent in this situation there is a rhesus-conflict.
The phenomenon is quite rare, butrepresents a significant threat to the life of the woman herself, as well as the life of the baby. With positive rhesus, the mother did not have conflicts with the fetus. But with negative it is necessary to check the blood of the father. If you get two "minus", then you should not worry. But if the pope has positive blood, then there is a possibility of conflict.
The mother's organism can take a positive rhesuskid as an enemy, a foreign body and try to get rid of it. Blood begins to produce antibodies - "protectors" of the body. Their number is determined during the analysis. If there is a threat, special means are introduced into the mother's body, medicines that inhibit the production of these cells - "defenders". Penetrating through the placenta into the baby's blood, these antibodies glue the red blood cells, destroying his body from the inside. Thus, there is a rhesus-conflict.
When the amount of antibodies reaches a certainmarks, the "struggle" begins. This mark is called the "critical mass". In most cases, the first pregnancy of a "negative" mother takes place without problems. But with the second bearing of the fetus, a conflict arises. If the child manages to survive and be born, then its red blood cells are partially damaged. The kid is diagnosed with hemolytic disease of the newborn. Then jaundice is manifested. Only a blood transfusion can save a baby. The donor, of course, must have a negative Rh factor of blood.
Opposite rhesus is by no means an excuseto renounce motherhood. You and your partner should be accurately identified with Rh-belonging to have reason for doubt or fear. An experienced doctor will tell you what to do in this case.
"Negative" moms will have to give blood more oftenon the analysis of the number of antibodies. Until the last month of pregnancy, the analysis is done once a month, but at the last month - twice, and so every week until the very birth. It is the amount of antibodies that can tell the doctor what a rhesus the baby is and whether there is a possibility of conflict. Anti-Rhesus immunoglobulin binds antibodies and removes them from the female body, preventing them from fighting the baby's blood cells. This vaccine helps to preserve the fetus. It can be administered either prophylactically or during pregnancy. The injection is inevitably done and after giving birth for three days.
Thanks to highly developed technologies, doctors solve the Rh-conflict positively, saving the life of both the baby and his mother.
The Rh factor of blood is another human identifier that characterizes its owner as an individual. When blood is transfused, its value is taken into account along with the blood group.
