Blood type of husband and wife is to blame

"Clinically often can see newborns hemolytic disease, the root causes of the disease is blood type of husband and wife.babyHalf the genetic material from the father, half from the mother, so is likely to inherit her mother's blood type, also may inherit father's blood type."Chaoyang hospital of pediatrics of doctor of vice director of gui-fang liang said in an interview that "if the mother in the fetus and the mother's blood type is different, the mother's body is equivalent to 'sensitization, the immune system, has rejected baby's blood type antibody, antibody combined with the surface of red blood cells in infants, cause hemolysis, baby hemolysis disease occurs."

Blood type consistency toTo get married？

Neonatal hemolysis disease caused by blood type out since it is husband and wife, so does everyone want to marry the same blood type people?Experts say there is no evidence that must be the same blood type to get married.Couples type out phenomenon is very common, so the newborn hemolytic disease is common, but generally can be found in time, timely treatment, the disease can cure almost, will not affect the future health of children.

According to introducing, although the fetus mother body depend on supply of nutrition, but there is a "placental barrier" between mother and fetus, the barrier can protect maternal blood "movement".But there are still a few baby red blood cells will penetrate into the maternal circulation, leading to the antibody, the mother's blood will also have a few blood into the foetus.Wait until after the child is born, the baby in the body with antibodies from the mother's blood will metabolic depletion in the agreed upon period of time, the child will soon be back to normal.

The mother O baby type A is the most susceptible

It is understood that the newborn hemolytic disease of the reason mainly is divided into two kinds: ABO blood group system, Rh blood group system.In our country, the most common is ABO blood group system, ABO hemolytic disease of the patient's mother had more for type O blood, baby how to type A or type B.

ABO hemolytic disease occur at a second child, but also can part happened in the first child.If the type O blood, universal recipients, the mother before the birth of lost A or B or AB blood, or had A history of miscarriage (mother's birth canal damage, been aborted fetal blood into the body), mother, after being "sensitization" produce antibodies against A or B.So even if the first child is also likely to produce neonatal hemolytic disease.Ms. Han had Zeng Huai pregnant, but because working relationship, had the abortion, so that the body would have produced A antibody, so the later born daughter heavier hemolysis disease occurs.

It is understood that the occurrence of neonatal hemolytic disease of the opportunities and severity, along with the tire time increases.In addition, some women it was the first time, but similar in the nature of ABO blood group substances, can enter the body through various pathways, antibodies, cause baby hemolytic disease of newborn.

The disease can't prevent but treatable

"Newborns hemolytic disease is common in clinic, but generally there will be no serious consequences, especially in recent years, along with the progress of medical technology, almost never had a dangerous cases."Liang Dafu said.

It is understood that the disease symptom has light is heavy, the baby is usually within 24 hours after birth, or the next day appear icteric, and quickly.Because the baby from the mother's antibodies in consume every day, so the symptoms will gradually improve.Baby there will be a severe anemia, and even "nuclear jaundice" namely bilirubin encephalopathy, is due to destruction of red blood cells to produce a material called bilirubin in the brain caused by, this is the most serious consequences.ABO blood group generally don't won't appear such result.

Mrs O and O the husband please pay more attention to when to have children

It is reported that because the baby is unable to control the choice of genetic material, so there is no any good way to prevent the disease.The doctor remind: if the husband is A, B or AB blood, his wife is O blood type, and had A history of miscarriage or history of blood transfusion,pregnancyShould think about this question, if necessary, can ask for my doctor's advice.

At the same time, according to a survey data also showed that blood type is 30% of pregnancies in China, the incidence of neonatal hemolysis disease was 11.9%, but there are few serious cases.
