Pregnancy also requires special attention to the Rh factor
Core Tip: Checking before pregnancy is very important, this helps you to give birth to a healthy baby, in addition to the general concern about the height and weight of the uterus attachment, you also need to pay attention to your cervix, Rh factor and so on.
Your pregnancy may make you need to deal with some problems before or during pregnancy. In this section, you will discuss these issues and tell you how important they are to your pregnancy.
Relaxation of the cervix
Cervical relaxation is the sterility of the cervix before fetal development matures. Pregnant women are often unaware of this situation. Breakage may occur without warning, leading to premature birth.
This condition is often diagnosed after one or more preterm births without prenatal pain and without abdominal pain. If this is your first pregnancy, you cannot know if you have cervical relaxation.
Some researchers believe that this happens because the cervix has had previous trauma, such as cervical dilatation and curettage for miscarriage. This situation may also occur after surgery on the cervix.
Surgical methods are commonly used to treat cervical relaxation. Sewn closure of the cervix can enhance lax cervix. After 36 weeks of gestation or when the pregnant woman delivers, the sutures are disassembled and the baby can be delivered normally.
Your Rh factor
Your blood type -- such as type A, type B, or type AB -- contains a factor that determines whether it is positive or negative. In the past, Rh-negative women who were pregnant with Rh-positive children faced a complicated pregnancy and could cause the child to be frail. Most of these problems are now preventable. If you are Rh negative, you and your doctor must know this. You will need special care during pregnancy and your baby's birth.
If you are Rh-negative and your baby is Rh-positive and you have had a pregnancy, blood transfusion, or some kind of blood product before, you are sensitized (Rh homologous immunization). This will affect the baby.
Cognate immunization
When Rh-positive blood enters the blood of an Rh-negative woman, a homeostatic effect (sensitization) occurs. This may occur in blood transfusions, or in children who have previously had Rh-positive children, miscarriage, and ectopic pregnancy.
If you have immune to your family, there is an antibody circulating in your body. They won't hurt you, but they can attack Rh-positive fetuses. Your body's antibodies can enter the fetus's blood through the placenta. This can make your baby anemic in the womb. This situation can be serious.
Prevention of problems
By applying (RhoGAM), an anti-Rh-r immunoglobulin, blood product, most problems can be solved. If you are Rh-negative and pregnant, anti-Rh-r immunoglobulin is injected at 28 weeks of gestation to prevent pre-delivery cohort immunization. If your baby is Rh positive, then within 72 hours after delivery, you should receive another injection of anti-Rh-r immunoglobulin.
If you cannot apply blood products for personal, religious, or ethical reasons, tell them to your doctor.
