It is said that raising a child is difficult, but in fact, having a child is also not easy. Women who are pregnant for ten months should always be prepared to face the risks of miscarriage, miscarriage, and various accidents. Some people even believe that blood type can affect the probability of miscarriage, and there are differences in the production of first and second children. So let's understand whether a second child with blood type O is prone to miscarriage?
Pregnant women with blood type O have a significantly increased risk of developing hemolytic disease of the newborn during their second pregnancy. If the fetus is incompatible with the mother's blood type, conditions such as miscarriage and fetal arrest may occur. Therefore, mothers with blood type O should be cautious when carrying a second child.
1、 What tests should be done for pregnant mothers with blood type O?
1. Determination of blood type antibodies: In ABO blood type incompatibility determination, if the antibody titer reaches 1:64, it is suspected of fetal hemolysis. If it reaches 1:512, it is highly suspected of fetal hemolysis. It is recommended to have a follow-up examination every few weeks during pregnancy.
2. B-ultrasound examination: B-ultrasound can observe the condition of the fetus and also determine the degree of hemolysis of the fetus.
3. Fetal heart rate monitoring: Mothers can do fetal heart rate monitoring from 32 weeks of pregnancy, which can determine whether the fetus is anemic or hypoxic.
4. Initial diagnosis of newborns: If a newborn experiences pale complexion, rapid heart rate, shortness of breath, etc., accurate judgment must be made immediately and timely treatment must be carried out.
2、 What are the precautions for having a second child?
1. Check before pregnancy: It is best to check whether you have hypertension, diabetes and other diseases. If you are not suitable for giving birth to a second child, you must carefully consider.
2. Control the interval between two deliveries: After giving birth to the first child, the mother must wait for her body to recover before considering having a second child.
3. Giving birth early: Older mothers face higher risks when giving birth to a second child. To improve the quality of the fetus, it is best to give birth at a young age.
