My mother is Rh- bloody, I am at risk

Mr. Nguyen Dinh Hoi and his wife, in Lac Hong, Yen Lac and Vinh Phuc communes, were overjoyed when they welcomed their second son. But, the next day, the child showed signs of jaundice and getting worse. I have hemolysis due to blood type disagreement with a mother with Rh- blood.

Two years earlier, Hoi's first son died after 3 days of birth with such a manifestation.

The mother and daughter were taken to the National Hospital of Pediatrics, Hanoi, but hoped to save the baby's life very little because the Rh- blood group was too rare, even large hospitals were not available. Thankfully, the Central Blood Transfusion Institute is the only place where this group has blood and reserves and saved the baby's life.

When it comes to blood type, people often refer to groups A, B, AB, O. It is the distinction between ABO blood type, the most common of about 23 blood group systems involving more than 200 antigens of red blood cells. But besides, there is a blood group that is very much related to the obstetrical ears that are Rh (Rhesus). This blood type system divides blood groups A, B, and O, AB divided into two types: Rh + or Rh-. Thus, a blood type A may be A Rh + or Rh-.

In the white community in Europe, the rate of Rh- is about 15%, while in our country, there are 7,000 people with this blood group for every 10,000 people.

People with Rh- blood group do not have antigens of Rh blood in the body (the most important is the antigen D), so they cannot resist the Rh's antigen. When the body is susceptible to this blood type, such as blood transfusion, delivery, it will produce antibodies against Rh +. From the second contact with Rh + blood group onwards, in the Rh- blood group, there will be a reaction between antibodies and Rh antigens and cause immunosuppression.

For example, a mother with a Rh- blood group has not had a blood transfusion ever, when pregnant, often has Rh + father-like blood type, the red blood cells of the Rh + blood group penetrate into the mother's blood, stimulating the mother's body to give birth. antibodies to Rh +. When pregnant for the second time, this antibody can be transmitted to the fetus, against the baby's red blood cells, causing complications such as pregnancy, neonatal hemolysis.

In addition, people with Rh- blood types who need transfusions need to mix both the ABO blood group and the Rh-type blood group.

Thus, to actively prevent disease, pregnant women should go to hematology departments for thorough advice and transmission of Anti-D, an antiserum of Rh- blood type, to ensure safety for both mother and baby at birth.
