An injection of anti-Rh antibodies (widely known by the trade name RhoGAM) given to the mother soon after birth neutralizes any fetal blood cells in their circulation before their immune system has a chance to respond. Subsequent pregnancies should be like the first, as if the woman was never exposed to the Rh factor.
Full Answer
Is it safe to have a baby with an Rh factor?
Usually your Rh factor blood type isn’t an issue. But during pregnancy, being Rh-negative can be a problem if your baby is Rh-positive. If your blood and your baby’s blood mix, your body will start to make antibodies that can damage your baby’s red blood cells. This could cause your baby to develop anemia and other problems.
What happens to the Rh factor during pregnancy?
During a pregnancy, Rh antibodies made in a woman’s body can cross the placenta and attack the Rh factor on fetal blood cells. This can cause a serious type of anemia in the fetus in which red blood cells are destroyed faster than the body can replace them.
What are the treatment options for Rh-negative pregnancy?
The goal of treatment is to stop an Rh-negative woman from making Rh antibodies in the first place. This is done by finding out if you are Rh negative early in pregnancy (or before pregnancy) and, if needed, giving you a medication to prevent antibodies from forming.
What happens if the father is Rh positive or Rh negative?
Rh Negative Mother is at risk if the father is Rh Positive. Usually Rh Negative Mother gives Birth to Rh +ve Baby. An Rh Negative Mother should be aware of her pregnancy and the blood group of her husband. If you are Rh-Positive, your red blood cells do have a marker called Rh factor on them. Rh-negative blood does not have this marker.
What happens if RhoGAM is not given after birth?
Risks of the RhoGAM shot — and not getting it In fact, 1 Rh negative pregnant woman in 5 will become sensitive to the Rh positive factor if she doesn't receive RhoGAM.

What happens if Rh incompatibility isn't treated?
Without that preventive treatment, Rh incompatibility destroys your baby's red blood cells (hemolytic anemia) during pregnancy. Red blood cells are filled with iron-rich protein (hemoglobin) that supplies oxygen to your baby. Your baby's red blood cells die faster than his or her body can make new ones.
What can happen if a woman who is Rh-negative has a second baby that is Rh positive?
If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign. Her antibodies will pass into the baby's bloodstream and attack those cells. This can make the baby's red blood cells swell and rupture.
What happens if you don't have Rh factor?
If the Rh factor protein is on the cells, the person is Rh positive. If there's no Rh factor protein, the person is Rh negative. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. There can be a problem when an Rh negative mother has a baby with an Rh positive father.
Does Rh incompatibility affect first pregnancy?
Firstborn infants are often not affected unless the mother had past miscarriages or abortions. This would sensitize her immune system. This is because it takes time for the mother to develop antibodies. All children she has later who are also Rh-positive may be affected.
What happens if mother and baby have different blood types?
If a baby's and mother's blood are incompatible, it can lead to fetal anemia, immune hydrops (erythroblastosis fetalis) and other complications.

Can I get pregnant if I am Rh sensitized?
Rh sensitization during pregnancy can only happen if a woman has Rh-negative blood and only if her baby has Rh-positive blood. If the mother is Rh-negative and the father is Rh-positive, there is a good chance the baby will have Rh-positive blood.

Why does a woman have more antibodies?
This is because her body does not have a chance to develop a lot of antibodies. But if treatment is not given during the first pregnancy and the woman later gets pregnant again with an Rh-positive fetus, she can make more antibodies. More antibodies put a future fetus at risk.

What happens when a baby's blood has a low number of red blood cells?
This means you have become sensitized and your antibodies can cross the placenta and attack your baby’s blood.

Avoiding fluid buildup
Researchers found that 24% of fetuses had fluid buildup without immunoglobulin treatment. This happened in only 4% of treated pregnancies.
Early delivery
An early delivery may be the best option for certain cases of Rh incompatibility. Once a fetus’s lungs have developed, a medical professional may recommend inducing labor. This can help protect the baby from any further risks while still inside the uterus.
Exchange transfusion
After delivery, doctors could recommend exchange transfusion. This process replaces a newborn’s blood with healthy donor blood. Exchange transfusion is particularly useful for babies who are born with jaundice.
Phototherapy
This treatment can also help treat jaundice in newborns. Phototherapy exposes the baby to as much light as possible. This helps lower the levels of bilirubin in a newborn’s blood.
