This is known as hemolytic or Rh disease of the newborn. It can make a baby's blood count get very low. How Is Rh Incompatibility Treated? If a pregnant woman has the potential to develop Rh incompatibility, doctors give her a series of two Rh immune-globulin shots during her first pregnancy.
How is Rh incompatibility treated?
If Rh Disease Is Not Prevented. Rh incompatibility rarely causes complications in a first pregnancy and does not affect the health of the mother. But if Rh antibodies develop, they could be dangerous to a fetus during later pregnancies. Rh disease can cause severe anemia, jaundice, brain damage, and heart failure in a newborn.
What happens if Rh disease is not prevented?
Rhesus (Rh) incompatibility refers to the discordant pairing of maternal and fetal Rh types. It is associated with the development of maternal Rh sensitization and hemolytic disease of the neonate (HDN).
What is Rh incompatibility in neonates?
If you're not sure what your Rh factor is and think you're pregnant, it's important to start regular prenatal care as soon as possible — including blood-type testing. With early detection and treatment of Rh incompatibility, you can focus on more important things — like welcoming a new, healthy baby.
What should I do if I don't know my Rh factor?
When should you get a shot to prevent blood incompatibility?
You should get a RhoGAM shot within 72 hours of the possible exposure to Rh-positive blood for the shot to work best. How safe is RhoGAM? RhoGAM is very safe. It is recommended for all pregnant women with Rh-negative blood type and has been used for about 50 years.
Can RhoGAM be given before 28 weeks?
Your doctor will administer at least one dose of RhoGAM Ultra-Filtered PLUS between 26 and 28 weeks of pregnancy. If your baby is found to be Rh-positive at birth, you will receive an additional dose within 72 hours after delivery.
How early can you give RhoGAM?
When should I get the RhoGAM shot? If your doctor determines that you may have Rh incompatibility, you'll get a shot of RhoGAM when you're between 26 and 28 weeks pregnant and then again within 72 hours after delivery to ensure that future pregnancies are as safe as the first.
How the Rh incompatibility can be avoided?
Rh incompatibility can be prevented with the use of RhoGAM. Therefore, prevention remains the best treatment. Treatment of an infant who is already affected depends on the severity of the condition. Infants with mild Rh incompatibility may be treated with phototherapy using bilirubin lights.
Can you get a RhoGAM shot at 5 weeks?
While it's important to be screened for the disease, Rh incompatibility is rare and preventable. To offset problems, your doctor can give you a shot of RhoGAM — generic: Rho(D) immune globulin — at about 28 weeks of pregnancy and whenever your blood may mix with your baby's, like during prenatal tests or delivery.
What happens if I don't get my RhoGAM shot at 28 weeks?
Like with skipping a vitamin K shot or with skipping or delaying vaccines, the risk of a baby developing hemolytic disease of the fetus and newborn isn't 100%, so these parents who skipped their RhoGAM shot gambled and got lucky their baby wasn't harmed.
Can Rh sensitization cause early miscarriage?
The Link Between Rh and Miscarriage Being Rh-negative in and of itself does not cause miscarriage or pregnancy loss. You are only at risk if you have been sensitized. The risk is very small if you have the recommended RhoGAM shots during pregnancy, or after an ectopic pregnancy, pregnancy loss, or induced abortion.
Do you give RhoGAM if baby is Rh-negative?
People who are Rh-negative should have a RhoGAM shot during their pregnancy. RhoGAM is effective in preventing Rh isoimmunization, a reaction that can cause harm to an unborn baby.
Can RhoGAM shot cause miscarriage?
In low-resource settings where Rh testing or use of RhoGAM is difficult, Rh unknown or negative status of a woman in the first trimester should not interfere with her ability to receive an abortion, as the risk to future pregnancies has not been documented.
Does Rh incompatibility affect first pregnancy?
Most Rh-positive babies born from a first-time pregnancy to a Rh-negative mother are not affected by Rh incompatibility.
What can be done if a mother is carrying a baby with incompatible blood?
In rare cases, if the incompatibility is severe and a baby is in danger, the baby can get special blood transfusions called exchange transfusions either before birth (intrauterine fetal transfusions) or after delivery. Exchange transfusions replace the baby's blood with blood with Rh-negative blood cells.
How often does Rh incompatibility occur?
Rh sensitization occurs in approximately 1 per 1000 births to women who are Rh negative. The Southwest United States has an incidence approximately 1.5 times the national average, which likely is caused by immigration factors and limited access to medical care since blood typing is a routine part of prenatal care.
What is the first test for rh incompatibility?
Rh Incompatibility During Pregnancy. One of the first tests a pregnant woman should expect is a blood-type test. This test checks her blood type and Rh factor. Her Rh factor may play a role in her baby's health, so it's important to know this information early in pregnancy.
When is the first shot of rh?
the first shot around the 28th week of pregnancy. the second shot within 72 hours of giving birth. Rh immune-globulin acts like a vaccine. It prevents the mother's body from making any Rh antibodies that could cause serious health problems in the newborn or affect a future pregnancy.
What happens if a baby has Rh disease?
This can make the baby's red blood cells swell and rupture. This is known as hemolytic or Rh disease of the newborn. It can make a baby's blood count get very low.
Why does the mother's body recognize the Rh protein?
That's because the baby's blood does not normally enter the mother's circulatory system during the pregnancy. During the birth, though, the mother's and baby's blood can mix. If this happens, the mother's body recognizes the Rh protein as a foreign substance.
Can a pregnant woman be exposed to rh?
It then might begin making antibodies (proteins that act as protectors if foreign cells enter the body) against the Rh protein. Rh-negative pregnant women can be exposed to the Rh protein that might cause antibody production in other ways too. These include: blood transfusions with Rh-positive blood. miscarriage.
Can a woman with rh negative conceive a baby?
(About half of the children born to an Rh-negative mother and Rh-positive father will be Rh-positive.) Rh incompatibility usually isn't a problem if it's the mother's first pregnancy.
Can you get rh if you have a miscarriage?
A woman also might get a dose of Rh immune-globulin if she has a miscarriage, an amniocentesis, or any bleeding during pregnancy. If a doctor finds that a woman has already developed Rh antibodies, her pregnancy will be closely watched to make sure that those levels are not too high.
What is the first test for rh incompatibility?
Rh Incompatibility During Pregnancy. One of the first tests a pregnant woman should expect is a blood-type test. This test checks her blood type and Rh factor. Her Rh factor may play a role in her baby's health, so it's important to know this information early in pregnancy.

Why are my children Rh positive?
Children may be Rh-positive if they inherit the protein from their father, even if their mother is Rh-negative.
What test do you do if you have Rh negative blood?
It may be done earlier if you have vaginal bleeding. If you have Rh-negative blood, your doctor may order another blood test, called an antibody screen.
Why do you need rhig injections after a positive blood test?
While an Rh-negative woman will not be harmed by contact with Rh-positive blood, she will need RhIg injections after every contact with Rh-positive blood to reduce risks for babies in a future pregnancy. These events include: Pregnancy, including miscarriage and abortion. Blood transfusions.
What is the rh factor?
Rh factor, also called Rhesus factor, is a type of protein found on the outside of red blood cells. The protein is genetically inherited (passed down from your parents). If you have the protein, you are Rh-positive. If you did not inherit the protein, you are Rh-negative. The majority of people, about 85%, are Rh-positive.
Can you have rh if you are pregnant?
This protein does not affect your overall health, but it is important to know your Rh status if you are pregnant. Rh factor can cause complications during pregnancy if you are Rh-negative and your child is Rh-positive.
Can you choose which Rh type your baby has?
Because Rh factor is genetic, it is not possible to choose which Rh type your baby has. However, if you are an Rh-negative woman with an Rh-positive baby, you can prevent Rh incompatibility by receiving RhIg at specific times during your pregnancy. It is an important topic to discuss with your healthcare provider.
Can a woman with rh negative be pregnant?
A woman who is Rh-negative is at risk for Rh incompatibility when she becomes pregnant. Rh incompatibility happens only when the father of the baby is Rh-positive. Doctors do not routinely test men’s Rh status. Instead, expectant parents discuss their individual status with their doctor.
Follow up with your doctor as directed
Write down your questions so you remember to ask them during your visits.
Prevent Rh factor incompatibility
Immune globulin (RhIg) shots may help reduce your risk. These shots prevent your body from making Rh antibodies. RhIg shots are usually given in the 28th week of pregnancy and within 72 hours after giving birth. You may need another shot if you have not given birth within 12 weeks after the first shot.

Medications
The most common way to stop these antibodies is through Rh immunoglobulin. Doctors administer this medication as an injection, and it prevents antibodies from developing in the pregnant person. This treatment program can prevent a fetus from developing anemia.
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.
WHAT YOU SHOULD KNOW
Rhesus (REE-sus) factor, or Rh factor incompatibility happens when you are Rh negative and you are carrying an Rh positive baby. Rh factor is a protein found on red blood cells. You are Rh positive (Rh+) if you have this protein in your blood. You are Rh negative (Rh-) if you do not have it.
Take your medicine as directed
Call your primary healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits.
Ask for information about where and when to go for follow-up visits
For continuing care, treatments, or home services, ask for more information.

Management of Rh Incompatibility
Once the risk of Rh incompatibility is found, the following steps can be taken to ensure the safety of the mother and baby:
Cost of Treatment
Management of this condition is without doubt, expensive . The baby might require NICU (neonatal ICU) facilities if the condition is severe and additional ventilator assistance.
