Infants with HDN may be treated with: Feeding often and receiving extra fluids. Light therapy (phototherapy) using special blue lights to convert bilirubin into a form which is easier for the baby's body to get rid of.
Which could result in hemolytic disease of the newborn?
Hemolytic disease of the newborn (HDN) is a blood problem in newborns. It occurs when your baby's red blood cells break down at a fast rate. It’s also called erythroblastosis fetalis.
Does anti-JRA cause hemolytic disease of the newborn?
The Jra antigen of the JR blood group system is a highly prevalent red blood cell antigen. Although anti - Jra -associated hemolytic disease of the fetus and newborn (HDFN) is generally considered mild-to-moderate, a rare fatal case was recently reported. We report the third example of HDFN-related anti - Jra with fatal outcomes. The clinical significance of anti - Jra antibody as a cause of HDFN ...
How is hemolytic disease of the newborn (HDN) diagnosed?
Tests conducted during pregnancy may include:
- complete blood count test for the mother
- ultrasound
- amniocentesis
- cordocentesis

What is the treatment for hemolytic disease of the newborn?
During pregnancy, treatment for HDN may include: Intrauterine blood transfusion of red blood cells into the baby's circulation. This is done by placing a needle through the mother's uterus and into the abdominal cavity of the fetus or directly into the vein in the umbilical cord.
How is the hemolytic disease of the newborn prevented?
Hemolytic disease of the newborn is very preventable. 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.
What is the best technique for monitoring the severity of hemolytic disease of the fetus and newborn?
The most important serologic test for the diagnosis of HDFN is the DAT with Ig G reagent. A positive DAT indicates sensitization of fetal red cells and is in itself not diagnostic of HDFN.
How is ABO incompatibility treated?
ABO incompatibility is treated in newborns by light therapy (phototherapy). On rare occasions an exchange transfusion may be necessary. Full recovery usually occurs with no lasting repercussions.
What is treatment for hemolytic anemia?
Treatments for hemolytic anemia include blood transfusions, medicines, plasmapheresis (PLAZ-meh-feh-RE-sis), surgery, blood and marrow stem cell transplants, and lifestyle changes. People who have mild hemolytic anemia may not need treatment, as long as the condition doesn't worsen.
How can you prevent hemolytic anemia?
You can't prevent inherited types of hemolytic anemia. One exception is glucose-6-phosphate dehydrogenase (G6PD) deficiency. If you're born with G6PD deficiency, you can avoid substances that may trigger the condition.
What is the most common treatment for hemolytic disease of the fetus and newborn HDFN due to ABO incompatibility?
Hemolytic disease of the newborn is managed by treating hyperbilirubinemia with phototherapy and exchange transfusions if needed.
What is the most common treatment for hemolytic disease of the fetus and newborn HDFN due to ABO incompatibility quizlet?
Intravenous immunoglobulin (IVIG) It contains antibodies to help the baby's immune system. IVIG reduces your baby's breakdown of red blood cells.
Which of the following medications would the nurse expect to administer for prevention of hemolytic disease of the fetus and newborn?
If you're Rh negative and have not been sensitized, you'll get a medicine called Rh immunoglobulin (RhoGAM). This medicine can stop your antibodies from reacting to your baby's Rh positive cells.
Why is RhoGAM 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.
How does exchange transfusion treat HDN?
Exchange transfusion removes circulating bilirubin and antibody-coated RBCs, replacing them with RBCs compatible with maternal serum and providing albumin with new bilirubin binding sites. The process is time consuming and labor intensive but remains the ultimate treatment to prevent kernicterus.
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.
What is the term for a newborn that breaks down red blood cells?
This condition occurs when there is an incompatibility between the blood types of the mother and baby. "Hemolytic" means breaking down of red blood cells. "Erythroblastosis" refers to making of immature red blood cells. "Fetalis" refers to fetus.
What happens when a baby has a Rh negative mother?
HDN most frequently occurs when an Rh negative mother has a baby with an Rh positive father. When the baby's Rh factor is positive, like the father's, problems can develop if the baby's red blood cells cross to the Rh negative mother. This usually happens at delivery when the placenta detaches. However, it may also happen anytime blood cells ...
Why is HDN accurate?
Because anemia, hyperbilirubinemia, and hydrops fetalis can occur with other diseases and conditions, the accurate diagnosis of HDN depends on determining if there is a blood group or blood type incompatibility.
What is the most severe form of hyperbilirubinemia?
The baby's liver is enlarged and anemia continues. Kernicterus. Kernicterus is the most severe form of hyperbilirubinemia and results from the buildup of bilirubin in the brain. This can cause seizures, brain damage, deafness, and death.
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.
Why does bilirubin cause yellowing?
This is called hyperbilirubinemia. Because bilirubin has a pigment or coloring, it causes a yellowing of the baby's skin and tissues. This is called jaundice.
What is the term for a baby's organs that are unable to handle anemia?
Hydrops fetalis. This occurs as the baby's organs are unable to handle the anemia. The heart begins to fail and large amounts of fluid build up in the baby's tissues and organs. A fetus with hydrops is at great risk of being stillborn.
What is the term for a condition where the mother's blood type is Rh negative and the baby is Rh positive
Douglas A. Nelson, MD. Updated on September 17, 2020. Hemolytic disease of the newborn (HDN) is a condition of red blood cell mismatch between a mother and her baby. This occurs when the mother's blood type is Rh-negative and the baby is Rh-positive. During the pregnancy the mother produces antibodies that attack and destroy red blood cells, ...
What is the name of the medication that a woman who is rh negative will receive?
If she doesn't already have antibodies, she will receive a medication called RhoGAM.
How long does it take for anemia to go away after delivery?
The maternal red blood cell antibodies can cause destruction for 4-6 weeks after delivery and additional transfusions may be needed.
What happens to a newborn after a first pregnancy?
After the first affected pregnancy, the severity of hemolytic disease of the newborn worsens with each pregnancy. Symptoms are determined by the severity of the red blood cell breakdown (called hemolysis). If the infant is only mildly affected, there may be minimal problems such as mild anemia and/or jaundice that do not require treatment.
What is the maternal immune system?
When maternal immune cells are exposed to the blood cells of the fetus (which can occur during delivery, bleeding during the pregnancy, or due to previous miscarriage), the maternal immune system recognizes the D antigen as "foreign" and develop antibodies against them.
What happens if a mother has anti-D antibodies?
If the mother is determined to have anti-D antibodies and the father is Rh-positive, there is the possibility of hemolytic disease of the newborn. In this situation, testing is performed on the amniotic fluid or blood from the umbilical cord to determine the blood type and group of the baby. If the baby is found to be Rh-negative, no further ...
Can the maternal immune system cause anemia?
However, in future pregnancies, if the maternal immune cells come into contact with the D antigen on the fetal blood cells, the immune system rapidly produces anti-D antibo dies that can cross the placenta . These antibodies attach to the fetal blood cells, marking them for destruction, causing anemia.
Introduction
Hemolytic disease of the newborn (HDN), also known as Erythroblastosis fetalis, is a hemolytic disorder that primarily affects Rhesus positive (Rh+) fetuses and newborns born to Rhesus negative (Rh-) mothers. A French midwife first described the disorder in 1609; however, it was not until the 1950s when the underlying cause was clarified.
Background
The knowledge of blood group systems is essential in clinical practice, especially for hematological disorders. The primary blood group systems in humans include the ABO and Rhesus systems. In 1904, Karl Landsteiner discovered the human blood groups.
Etiology
HDN is commonly caused by the incompatibility of the mother’s and the baby’s blood. Suppose the baby’s blood crosses over and reaches the mother’s incompatible RBCs; the mother’s immune system perceives the fetal antigens as non-self and fights them by releasing antibodies that do not hesitate to attack and destroy them.
Diagnosis
To diagnose and manage pregnant women with HDN, extensive laboratory and imaging practice is required. HDN is clinically indicated by: (1) rapid and severe hyperbilirubinemia or persistent hyperbilirubinemia; and (2) hemolysis on blood film results. 44 It should also be noted that the extent of hematopoiesis affects the severity of the disorders.
Patient Care and Prevention
When the testing results indicate anemia in the uterus, group O negative blood transfusion should begin. The transfused blood type O negative should be cross-matched with maternal blood. This procedure is best completed between the ages of 16 and 18.
Potential Complications of Exchange and Transfusion
Several complications may be experienced during a blood transfusion. It is critical to have an initial understanding of such prospective difficulties to establish remedies and handle them.
Trends and Future Prospects
Blood typing using molecular methods is becoming more common as molecular testing becomes more widely used in medicine. Serological probes do not always correctly identify the RhD type in some individuals. Weak D phenotypes seem to be the most common genetic background that accounts for this serological typing problem.
What is the best treatment for bilirubin in newborns?
Feeding often and receiving extra fluids. Light therapy ( phototherapy) using special blue lights to convert bilirubin into a form which is easier for the baby's body to get rid of. Antibodies (intravenous immunoglobulin, or IVIG) to help protect the baby's red cells from being destroyed.
What is hemolytic disease?
Share. Hemolytic disease of the newborn (HDN) is a blood disorder in a fetus or newborn infant. In some infants, it can be fatal.
What is erythroblastosis fetalis?
Erythroblastosis fetalis is a condition manifested by anemia that develops in an unborn infant when maternal antibodies , usually caused by Rh incompatibility between the mother's blood type and that of the fetus, attack the red blood cells of the fetus. An intrauterine transfusion of blood may be indicated.
What does rh mean in blood?
Rh is short for the "rhesus" antigen or blood type. People are either positive or negative for this antigen. If the mother is Rh-negative and the baby in the womb has Rh-positive cells, her antibodies to the Rh antigen can cross the placenta and cause very severe anemia in the baby. It can be prevented in most cases.
How long do red blood cells last in a newborn?
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.
Can HDN cause jaundice?
HDN can destroy the newborn baby's blood cells very quickly, which can cause symptoms such as: Edema (swelling under the surface of the skin) Newborn jaundice which occurs sooner and is more severe than normal.
Can a baby die from hydrops?
Some babies have no symptoms. In other cases, problems such as hydrops can cause the baby to die before, or shortly after, birth. Severe HDN may be treated before birth by intrauterine blood transfusions.
Causes Of HDN
HDN occurs when the fetus and the mother have different blood groups and Rh factors. The condition most commonly occurs when the baby is Rh-positive while the mother is Rh-negative, irrespective of their blood groups (1).
Risk Factors For HDN
The following events and conditions could directly or indirectly increase the chances of Rh-sensitization, in turn increasing the risk of HDN (2).
Effects Of HDN On Babies
HDN causes rapid destruction of the baby’s RBCs, leading to the following problems in the fetus and newborn (3).
Symptoms Of HDN
The following are the commonly seen signs and symptoms of HDN during the fetal stage and when the baby is born (4).
Treatment For HDN
The doctor may suggest the following treatment methods depending on the stage of diagnosis of HDN (4).
Prevention Of HDN
HDN due to Rh incompatibility is preventable. Rh-negative mothers who have not been Rh-sensitized can receive injectable Rh immunoglobulin, also called RhoGAM, around the 28th week of pregnancy. It prevents the maternal Rh antibodies from reacting with the baby’s Rh-positive blood.
