Guide | How Hydrops Fetalis Can Threaten a Baby's Life
Hydrops fetalis is a serious condition involving excessive fluid accumulation in a fetus or newborn. Fluid may collect anywhere in the body, most often in the abdomen, around the heart and lungs, and beneath the skin. Without timely treatment, this fluid places severe strain on the heart and other vital organs and can be life-threatening.
Symptoms of Hydrops Fetalis
Symptoms vary by baby but commonly include:
During pregnancy:
Excess amniotic fluid
Thickened placenta
Enlarged spleen and heart
Fluid around fetal organs, the heart, or lungs
After birth:
Pale skin
Profuse sweating
Difficulty breathing
Enlarged liver and spleen
Types of Hydrops Fetalis
There are two types:
Nonimmune hydrops fetalis: The most common type, accounting for 80-90% of cases. It is generally caused by a genetic disorder or congenital defect that affects the baby's ability to regulate fluid.
Immune hydrops fetalis: This rare type generally occurs when maternal and fetal red blood cells are incompatible. For example, if the mother is Rh-negative and the baby is Rh-positive, the mother's immune system may recognize fetal red blood cells as foreign and produce antibodies against them. This can cause severe anemia and potentially heart failure in the baby.
Causes
Hydrops fetalis is not itself a disease but results from another medical condition. Common causes include:
Hemolytic disease of the newborn: A blood disorder caused by maternal-fetal blood type incompatibility.
Severe anemia: Too few red blood cells to carry sufficient oxygen.
Infection: An infection present at birth may cause hydrops.
Heart or lung defects: Abnormal development of the heart or lungs increases risk.
Birth defects and congenital abnormalities: These can increase the risk of hydrops.
Liver disease: Jaundice and abdominal swelling from liver disease may be accompanied by hydrops.
Diagnosis
Hydrops fetalis is usually identified during routine prenatal ultrasound. Abnormal fluid in two or more fetal compartments may indicate the condition. Clinicians also check for excess amniotic fluid, a thickened placenta, and an enlarged heart, liver, or spleen. Blood tests can assess red blood cell incompatibility between mother and baby.
Treatment
Treatment options may be limited when hydrops is diagnosed during pregnancy, and early delivery may be necessary in some cases. Newborns with hydrops generally require specialized medical care, including possible ventilator support. A clinician may drain excess fluid from around the heart, lungs, or abdomen with a needle. The baby requires close hospital monitoring until the underlying condition is controlled and stable.
