Hydrops is severe swelling in the body tissues of a fetus or infant.
What is Pediatric Hydrops?
Hydrops is severe swelling in the body tissues of a fetus (unborn child) or infant (birth to 1 year*). The condition develops when too much fluid moves from the baby’s bloodstream into the tissues. Hydrops can cause a fetus or baby’s organs to shut down, and it can be fatal.
The most common places for the fluid to build up is in tissues around the lungs, heart, or abdomen (ascites), and under the skin (edema).
What are the different types of Pediatric Hydrops?
There are two types of hydrops:
If mother and baby do not have the same blood type, the mother’s immune system may begin to break down the red blood cells of the fetus during pregnancy, causing swelling.
If a fetus or newborn has a disease that makes it hard for their body to manage fluids, hydrops can develop. Examples of diseases that may cause hydrops include severe anemia, congenital infections, heart conditions, lung conditions, chromosome defects and liver disease.
What are the signs and symptoms of Pediatric Hydrops?
Symptoms of hydrops can be found during pregnancy or after birth.
