If women are at risk, measure antibody levels and, if needed, middle cerebral artery blood flow periodically. Treat erythroblastosis fetalis with intrauterine fetal blood transfusions as needed and, if severe fetal anemia is detected, delivery at 32 to 35 weeks, depending on the clinical situation.
Is erythroblastosis fetalis life-threatening?
This is a life-threatening condition. A buildup of bilirubin in the brain can lead to a complication called kernicterus, leading to seizures, brain damage, deafness, or death. The first step in diagnosing erythroblastosis fetalis is to determine whether the cause is Rh incompatibility.
How is erythroblastosis fetalis (EPF) treated during pregnancy?
Pregnancy is usually followed by an interprofessional team that includes the obstetric nurse. These professionals need to ensure that pregnant women do not develop erythroblastosis fetalis because it is preventable. Throughout pregnancy, the antibody titer is followed approximately every 4 weeks.
What are the symptoms of erythroblastosis fetalis during pregnancy?
Symptoms of erythroblastosis fetalis during pregnancy may show up during routine testing. Newborns with the condition may display visible symptoms as well as some that show up on scans, such as: Hydrops fetalis is another severe complication that causes fluid to build up in fetal tissues and organs as a result of heart failure.
How is erythroblastosis fetalis diagnosed?
How is erythroblastosis fetalis diagnosed? To diagnose erythroblastosis fetalis, a doctor will order a routine blood test during your first prenatal visit. They’ll test for your blood type. The test will also help them determine whether you have anti-Rh antibodies in your blood from a previous pregnancy.
What is the treatment of erythroblastosis fetalis?
How is erythroblastosis fetalis treated? If a baby experiences erythroblastosis fetalis in the womb, they may be given intrauterine blood transfusions to reduce anemia. When the baby's lungs and heart mature enough for delivery, a doctor may recommend delivering the baby early.
What is erythroblastosis fetalis What is the cause who is at risk How is it treated?
erythroblastosis fetalis, also called hemolytic disease of the newborn, type of anemia in which the red blood cells (erythrocytes) of a fetus are destroyed in a maternal immune reaction resulting from a blood group incompatibility between the fetus and its mother.
What is erythroblastosis fetalis how can be erythroblastosis fetalis avoided in a pregnant woman immediately after the delivery of the first child?
Statement-l Erythroblastosis foetalis occurs between Rh-ve mother and Rh +ve foetus after first pregnancy. Statement-Il : Erythroblastosis foetalis can be avoided by administering Rh antigens to mother immediately after delivery of first child in all cases.
How does erythroblastosis occur?
Hemolytic disease of the fetus and newborn (HDFN) is also known as alloimmune HDFN or erythroblastosis fetalis. It is caused by the destruction of neonatal red blood cells by maternal immunoglobulin G (IgG) antibodies. The formation of maternal antibodies in response to a fetal antigen is called isoimmunization.
What is erythroblastosis fetalis and when does it occur?
Erythroblastosis fetalis is hemolytic anemia in the fetus (or neonate, as erythroblastosis neonatorum) caused by transplacental transmission of maternal antibodies to fetal red blood cells. The disorder usually results from incompatibility between maternal and fetal blood groups, often Rho(D) antigens.
What is the treatment for Rh incompatibility?
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.
How can be erythroblastosis foetalis avoided in a pregnant woman immediately after the delivery of the first child class 11?
Statement-Il : Erythroblastosis foetalis can be avoided by administering Rh antigens to mother immediately after delivery of first child in all cases.
What causes erythroblastosis fetalis how it can be avoided?
Erythroblastosis fetalis is hemolytic anemia in the fetus (or neonate, as erythroblastosis neonatorum) caused by transplacental transmission of maternal antibodies to fetal red blood cells. The disorder usually results from incompatibility between maternal and fetal blood groups, often Rho(D) antigens.
Why is erythroblastosis fetalis fatal for second pregnancy?
Most problems occur in future pregnancies with another Rh positive baby. During that pregnancy, the mother's antibodies cross the placenta to fight the Rh positive cells in the baby's body. As the antibodies destroy the cells, the baby gets sick. This is called erythroblastosis fetalis during pregnancy.
How long does hemolytic disease of the newborn last?
Hemolytic disease of the newborn (HDN) is a blood disorder in a fetus or newborn infant. In some infants, it can be fatal. Normally, red blood cells (RBCs) last for about 120 days in the body. In this disorder, RBCs in the blood are destroyed quickly and thus do not last as long.
When is RhoGAM given?
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.
Why are RhoGAM injections given?
Getting a RhoGAM shot is the best way to prevent any possible complications from Rh incompatibility. It protects your baby's red blood cells from attack if her blood comes into contact with yours during labor and delivery and helps prevent Rh-related complications from happening in later pregnancies.
What causes erythroblastosis fetalis?
There are two main causes of erythroblastosis fetalis: Rh incompatibility and ABO incompatibility. Both causes are associated with blood type. There are four blood types: In addition, blood can be either Rh positive or Rh negative. For example, if you’re type A and Rh positive, you have A antigens and Rh factor antigens on the surface of your RBCs.
When can you test your blood for Rh negative?
However, if the father’s blood type is Rh positive or their blood type isn’t known, your blood may be tested again between 18 to 20 weeks of pregnancy, and again at 26 to 27 weeks.
Why do you give blood transfusions to a baby?
If a baby experiences erythroblastosis fetalis in the womb, they may be given intrauterine blood transfusions to reduce anemia. When the baby’s lungs and heart mature enough for delivery, a doctor may recommend delivering the baby early. After a baby is born, further blood transfusions may be necessary.
What is the condition where the mother's blood type isn't compatible with the baby's blood type?
ABO incompatibility. Another type of blood type mismatch that can cause maternal antibodies against her baby’s blood cells is ABO incompatibility. This occurs when the mother’s blood type of A, B, or O isn’t compatible with the baby’s. This condition is almost always less harmful or threatening to the baby than Rh incompatibility.
How often do you have to have a fetal transfusion?
Transfusions occur every 1 to 2 weeks, usually until 32 to 35 weeks. During that time period, delivery may be recommended if there is continuing evidence of severe fetal anemia (based on MCA blood flow). The woman may continue to term delivery if there is no evidence of severe fetal anemia based on MCA blood flow.
How long does it take for a baby to be delivered?
Sometimes delivery at 32 to 35 weeks. If fetal blood is Rh negative or if MCA blood flow remains normal, pregnancy can continue to term untreated. If fetal anemia is likely, the fetus can be given intravascular intrauterine blood transfusions by a specialist at an institution equipped to care for high-risk pregnancies.
What is fetal DNA screening?
Cell-free fet al DNA screening. At the first prenatal visit, all women are screened for blood type, Rh type, and anti-Rho (D) and other antibodies that are formed in response to antigens and that can cause erythroblastosis fetalis (reflex antibody screening). If women have Rh-negative blood and test positive for anti-Rho ...
How long after termination of pregnancy can you give IM?
Because fetomaternal transfer and likelihood of sensitization is greatest at termination of pregnancy, the preparation is given within 72 hours after termination of each pregnancy, whether by delivery, abortion, or treatment of ectopic pregnancy. The standard dose is 300 mcg IM.
How often do you measure maternal antigens?
If titers are positive but less than a laboratory-specific critical value (usually 1:8 to 1:32), they are measured every 2 to 4 weeks after 20 weeks.
When is MCA blood flow measured?
If the critical value is exceeded, fetal middle cerebral artery (MCA) blood flow is measured at intervals of 1 to 2 weeks depending on the initial blood flow result and patient history; the purpose is to detect high-output heart failure, indicating high risk of anemia.
Is fetal anemia likely if MCA blood flow is elevated?
If fetal blood is Rh positive or status is unknown and if MCA blood flow is elevated, fetal anemia is likely .
What is erythroblastosis fetalis?
It is a blood disorder that occurs when the blood types of a mother and baby are incompatible. It is also called as hemolytic disease of the newborn (HDN).
When was erythroblastosis first diagnosed?
Erythroblastosis Fetalis treatmentwas first identified in 1932 at Boston Children’s Hospital by Dr. Louis Diamond. He went on to develop the first successful treatment for Erythroblastosis Fetalis through transfusion procedure, in the 1940s. Erythroblastosis Fetalis Definition.
Why is erythroblastosis more likely to occur during a second pregnancy?
Because of this, Erythroblastosis Fetalis is more likely to occur during a mother’s second or subsequent pregnancy, or following a miscarriage or abortion.
Can erythroblastosis be treated during pregnancy?
Erythroblastosis Fetalis can be treated during pregnancy or after the baby is born.
Is erythroblastosis fetalis preventable?
Erythroblastosis Fetalis is very preventable. Erythroblastosis Fetalis prevention is easy. Today, nearly all women with Rh-negative blood are identified in early pregnancy through blood tests. If a mother is Rh-negative and has not been sensitized, she is usually given a drug called Rh immunoglobulin, or RhoGAM. This specially developed blood product prevents a Rh-negative mother’s antibodies from reacting to her baby’s Rh-positive red blood cells. Mothers are typically given RhoGAM around the 28th week of pregnancy and again within 72 hours of giving birth.
Why does erythroblastosis occur in fetal blood?
Erythroblastosis fetalis only occurs when the mother is Rh-. Erythroblastosis fetalis occurs as a result of the sensitization of the mothers Rh- blood due to exposure to Rh-D antigens either by blood transfusion ...
Why do Rh+ babies have erythroblastosis fetalis?
As a result of the production of anti-bodies, subsequent Rh+ babies will be subjected to erythroblastosis fetalis because the body of the synthesized mother will attack the baby’s red blood cell due to the presence of Rh-D antigens.
What is the first step in a pregnancy?
The first step of diagnosis is prenatal maternal blood typing and screening. The blood group and Rhesus factor of the woman is determined. She is also screened for anti-RhD and any other anti-bodies that may have developed due to exposure of any of the antigens that may lead to erythroblastosis fetalis.
What causes erythroblastosis in neonates?
Erythroblastosis fetalis of neonates, also erythroblastosis neonatorum or hemolytic anemia of the newborn is caused by the transmission of antibodies to the red blood cell of the fetus through the placenta in intrauterine life. It is caused by incompatibility of the maternal blood group and the fetal blood group, ...
What happens if the father has no antigens?
If the father has neither of the antigens, then the child will be 100 percent free of these antigens and will be free of erythroblastosis fetalis.
What happens if a mother is Rh+?
If the mother is found to be Rh+, normal pregnancy procedures are carried on. If the mother is Rh- and has any of the anti-bodies caused by erythroblastosis fetalis causing antigens, then the next step will be to test the blood of the father, if the paternity of the child is certain.
When is Rh+ given?
When the Rh- woman is pregnant with her first Rh+ baby and she has not been previously sensitized, she is given Rh-D immune globulin at: 28th week of pregnancy. 72 hours of terminating the pregnancy either by delivery or abortion or treatment of ectopic pregnancy. After any occurrence of vaginal bleeding.
What is the term for a newborn's blood cells that are not able to do the work of mature red
The blood cells produced in these other organs are usually immature and are not able to do the work of mature red blood cells and are referred to as erythroblasts . This causes erythroblastosis fetalis. In the newborn, the resulting condition is called hemolytic disease of the newborn (HDN).
What happens to the baby when the mother's antibodies cross the placenta?
As the antibodies destroy the red blood cells, the baby can become sick. This is called erythroblastosis fetalis during pregnancy. In the newborn, the condition is called hemolytic disease of the newborn.
What is the term for a baby with an immune system that attacks the blood cells of the Rh positive baby?
Erythroblastosis fetalis also called immune hydrops or Rh disease during pregnancy, that occurs when Rh-negative mother’s immune system attacks the blood cells of the Rh-positive baby. For example, a mother who has an Rh-negative blood type who is carrying a baby with an Rh-positive blood type may have an immune response ...
What are the complications of Rh?
Some of the more common complications of Rh disease for the fetus and newborn baby include the following: Anemia (in some cases, the anemia is severe with enlargement of the liver and spleen) Jaundice. This is a yellowing of the skin, eyes, and mucous membranes. Hydrops fetalis.
Does erythroblastosis fetalis cause rh sensitization?
In a first pregnancy, Rh sensitization is not likely. Usually, erythroblastosis fetalis only becomes a problem in a future pregnancy with another Rh positive baby.
What organs do babies need to fail?
These include the liver, kidneys and adrenal gland. The baby’s heart is also affected because the low blood count causes it to have to work harder and it can eventually fail.
Is erythroblastosis fetalis more likely in African American babies than in Caucasian
Erythroblastosis fetalis due to Rh incompatibility is about three times more likely in Caucasian babies than African-American babies. In a first pregnancy, Rh sensitization is not likely. Usually Rh disease only becomes a problem in a future pregnancy with another Rh positive baby.
Blood tests
Your baby's bilirubin and RBC levels may need to be checked after he or she leaves the hospital. You may need to bring your baby to your pediatrician's office or a lab to have this done. Your baby's bilirubin level may reach a very high level after he or she leaves the hospital.
Follow up with your baby's doctor as directed

Erythroblastosis fetalis
is a condition that causes your unborn baby's red blood cells (RBCs) to break down. This may cause severe anemia (low RBC count). Anemia makes it difficult for the RBCs in your baby's blood to carry enough oxygen to his or her body. This condition is also called hemolytic disease of the newborn. Hemolysis means breaking down RBCs.
Treatment
Blood transfusions may be given to your baby through the umbilical cord.
