Because differ with marital blood type, abortion, stillborn foetus appears during concern of a little young woman is pregnant or postpartum occurrence new student haemolysis disease, the mother embryo blood group that tells on medicine namely shoulds not. That is the husband and wife of all and different blood type, appear likely does mother embryo blood type should not? Next we learn understanding together.
What understanding above all is disagreement of mother embryo blood type, and what problem can disagreement of mother embryo blood type have?
Disagreement of mother embryo blood type is pregnant woman and fetal between, because of the disease of immunity of agnate blood type that blood type shoulds not and produces, can make agglutinate of fetal red blood cell is destroyed, cause fetal or new student haemolysis disease. Abortion, fetal oedema, stillborn foetus can be brought about in gestation; In the new student period can appear to send a gender early icteric, serious person can produce a nucleus icteric, cause a new life death, although survive to also can affect growth of cell of little patient nerve, bring about what intelligence reachs athletic capacity to drop.
Then, the cent that will we come to know blood type be what kind of?
In ABO blood type:
A blood type person, there is A antigen in blood, have fight B antibody;
B blood type person, there is B antigen in blood, have fight A antibody;
AB blood type person, there is antigen of A, B in blood, without fight antibody of A, B;
O blood type person, antigen of A, B is not had in blood, have fight antibody of A, B.
Additionally still blood type still divides Rh negative and Rh positive two kinds inferior model, red blood cell of laic body blood contains D antigen (call Rh antigen again) the positive that it is Rh, it is negative otherwise. Among them Rh electronegative crowd is less, common calls panda blood.
So, is disagreement of mother embryo blood type how happen?
When parental blood type is different, fetal the antigen of dominance of red blood cell from agnate heredity just is lacked for maternal place, for example the mother is O model, without antigen of A, B, or RH is electronegative, without D antigen, between the pregnancy that be like a bosom, there are certain blemish or crack on placental protective screen, fetal red blood cell has an opportunity to enter the mother's body; Or going to already in process of gravid, delivery, fetal antigen invades the mother's body, make the mother's body is sent quick, produce corresponding akin immunity antibody. Antibody enters fetal loop through placenta again, photograph of antigen, antibody is united in wedlock, make agglutinate of red blood cell is destroyed and produce haemolysis.
From above we knew mother embryo blood type cent of disagreement, blood type and the principle that mother embryo blood type shoulds not, discover not hard, connubial blood type is different, only pregnant woman is O model or when Rh negative blood type, just blood type of embryo of opportunity happening mother shoulds not. According to statistic, be in our country, disagreement of ABO blood type is gravid occupy always be born 27.7% of several, among them 20% come on, the person that have clinical symptom occupies 2%~2.5% only. And Rh blood type shoulds not, incidence of a disease is between 0.34%~0.74% , once produce a patient's condition heavier. And connubial blood type is different, the blood type of mother embryo is possible also same. Accordingly, because connubial blood type differs to worry too,do not produce mother embryo blood type to should not, when necessary specialized subject outpatient service seeks advice but.
