Learn about Symptoms, Causes, Jaundice Risks, and Legal Help
Hemolytic Disease of the Fetus and Newborn, or HDFN, is a serious blood condition that can happen when a mother’s immune system attacks a baby’s red blood cells. A blood type mismatch between the mother and baby usually causes HDFN.
Because the mother’s immune system sees the baby’s red blood cells as foreign, it creates antibodies against the blood cells. When too many red blood cells are destroyed, it can cause major health problems and, in severe cases, death.
Cases of HDFN can range from mild to moderate to severe. While some babies only need close monitoring and light therapy, others may need IVIG, blood transfusions, exchange transfusion, NICU care, or treatment before birth.
Symptoms of Hemolytic Disease of the Newborn
Symptoms of HDFN can appear before birth, right after birth, or during the first few days of the baby’s life. Some signs may be obvious, while others require blood testing to detect.
Common symptoms may include:
- Yellowing of the skin or eyes.
- Jaundice that appears within the first 24 hours after birth.
- Pale skin.
- Poor feeding.
- Extreme sleepiness or difficulty waking.
- Weak cry.
- Low muscle tone or floppy movement.
- Dark urine.
- Swollen belly.
- Enlarged liver or spleen.
- Fast breathing or trouble breathing.
- Rapid heartbeat.
- Low red blood cell count.
- High bilirubin levels.
- Positive Coombs test or direct antiglobulin test.
- Seizures in severe cases.
- Abnormal arching of the body or neck.
- High-pitched crying.
- Fluid buildup in the baby’s body before birth also known as hydrops fetalis.
Injuries Caused by Hemolytic Disease of the Newborn
When red blood cells are destroyed faster than the baby’s body can replace them, HDFN can cause serious complications and injuries. If the baby does not have enough healthy red blood cells to carry oxygen, it can develop anemia. Severe cases of anemia can make the heart work harder and may lead to heart failure, swelling, and fluid buildup before birth.
HDFN is also known to cause severe cases of jaundice. When bilirubin gets too high, it can move into brain tissue and cause major injuries. That can include acute bilirubin encephalopathy, kernicterus, hearing loss, movement problems, developmental delays, cerebral palsy-like symptoms, seizures, or lifelong disability.
In particular, kernicterus is concerning because it is a form of brain damage caused by very high bilirubin levels and can occur when severe jaundice is not treated in time.
In the most severe cases, HDFN can cause hydrops fetalis, which is one of the most severe complications. This means the baby develops abnormal fluid buildup in the body. Hydrops can cause breathing problems, heart failure, lung problems, and death before or after birth.
Possible Medical Malpractice Involving HDFN
Medical malpractice occurs when a doctor, nurse, hospital, or other provider fails to provide the accepted standards of care and that failure causes harm.
In cases of HDFN, negligence may arise from errors during pregnancy, labor, delivery, newborn care, discharge, or follow-up.
Possible examples include:
- Failing to test the mother’s blood type and Rh status.
- Failing to order an antibody screen during pregnancy.
- Failing to recognize a positive antibody screen.
- Failing to give Rho(D) immune globulin when medically indicated.
- Failing to give Rho(D) immune globulin after delivery, miscarriage, trauma, bleeding, amniocentesis, or another sensitizing event.
- Failing to identify a pregnancy as high-risk after maternal antibodies are found.
- Failing to refer the mother to a maternal-fetal medicine specialist.
- Failing to monitor the fetus for signs of anemia or hydrops fetalis.
- Failing to plan delivery at a hospital equipped to treat a high-risk newborn.
- Failing to test the newborn’s bilirubin level when jaundice appears.
- Relying only on visual checks instead of bilirubin testing.
- Ignoring jaundice that appears in the first 24 hours of life.
- Delaying phototherapy, IVIG, transfusion, or exchange transfusion.
- Discharging the baby without proper follow-up for jaundice.
- Failing to warn parents about signs of worsening jaundice, poor feeding, lethargy, or abnormal behavior.
- Failing to respond when parents report that something is wrong.
Hemolytic Disease of the Fetus and Newborn (HDFN) FAQs
Is Hemolytic Disease of the Fetus and Newborn the same as jaundice?
No. Jaundice is a symptom, while Hemolytic Disease of the Fetus and Newborn is one possible cause of jaundice. Many newborns develop mild jaundice because their bodies are still learning how to process bilirubin.
HDFN is different because the baby’s red blood cells are being destroyed by maternal antibodies. This can cause bilirubin to rise faster and earlier than normal newborn jaundice. Jaundice caused by HDFN may appear within the first 24 hours after birth, which is a warning sign that the baby needs to be seen by a doctor.
What causes HDFN in newborns?
HDFN is usually caused by blood type incompatibility between the mother and baby. Rh incompatibility can happen when an Rh-negative mother carries an Rh-positive baby and becomes sensitized to Rh-positive blood. ABO incompatibility can happen when the mother has type O blood, and the baby has type A or B blood. Other blood group antibodies can also cause HDFN. These antibodies can cross the placenta and attack the baby’s red blood cells, leading to anemia, jaundice, and other complications.
Can HDFN be prevented?
With proper prenatal care, some cases of HDFN can be prevented, especially Rh-related disease.
For instance, some medications can prevent maternal sensitization in many Rh-negative patients. Pregnant patients should have blood type and antibody screening.
Rh-negative mothers may need Rho(D) immune globulin during pregnancy, after delivery, or after events where fetal and maternal blood may mix. Prevention depends on providers recognizing the risk and acting quickly.
How do doctors diagnose Hemolytic Disease of the Fetus and Newborn?
HDFN can be diagnosed by using the mother’s prenatal blood work and the baby’s newborn testing. The mother’s tests should include ABO blood type, Rh status, and antibody screening.
After birth, the baby may need blood type testing, bilirubin testing, hemoglobin or hematocrit testing, and a direct antiglobulin test, also known as a direct Coombs test. Doctors may watch for jaundice, pale skin, poor feeding, sleepiness, swelling, or breathing problems. In pregnancy, if maternal antibodies suggest a risk of fetal anemia, fetal monitoring may be necessary.
Why is jaundice in the first 24 hours concerning?
Jaundice in the first 24 hours of life can be a sign that bilirubin is rising too early or too quickly. One possible cause is hemolysis, in which red blood cells break down faster than normal. HDFN is a known cause of hemolysis in newborns.
Early jaundice typically leads to a prompt medical evaluation, which includes bilirubin testing and risk assessment. Waiting too long can allow bilirubin to rise to dangerous levels. Severe, untreated jaundice can cause permanent brain damage.
When can HDFN become a medical malpractice issue?
If medical providers fail to follow reasonable steps to identify, monitor, or treat the condition, it may be a case of medical malpractice; Examples may include failing to check the mother’s blood type, missing a positive antibody screen, failing to give Rho(D) immune globulin when indicated, ignoring early jaundice, delaying bilirubin testing, delaying phototherapy or exchange transfusion, or sending a baby home without proper follow-up care instructions.
The biggest question is whether the provider’s mistake caused preventable harm. A medical malpractice attorney, such as the team at Weisser Law, can review the records to determine what happened and whether the healthcare providers followed the accepted standards of care.
