How do you manage fetal hydrops?
How is hydrops fetalis treated?
- using a needle to remove excess fluid from the space around the lungs, heart, or abdomen (thoracentesis)
- breathing support, such as a breathing machine (ventilator)
- medications to control heart failure.
- medications to help the kidneys remove excess fluid.
What is non-immune hydrops fetalis?
Disease definition. Non-immune hydrops fetalis (NIHF), a form of HF, is a severe fetal condition defined as the excessive accumulation of fetal fluid within the fetal extravascular compartments and body cavities, and is the end-stage of a wide variety of disorders.
What is the most common cause of hydrops fetalis?
Among the infectious etiologies, the most common causes are cytomegalovirus (CMV), toxoplasmosis, syphilis, and B19V infection. Infectious causes of hydrops fetalis are as follows: B19V. CMV.
What causes hydrops fetalis in pregnancy?
Immune hydrops is caused by an incompatibility of red blood cells between the mother and her unborn baby. That incompatibility leads to the destruction of a large number of the baby’s red blood cells (also known as hemolytic disease).
How is hydrops fetalis diagnosis?
Doctors diagnose hydrops prenatally using an ultrasound. If there is abnormal or increased fluid collection in at least two fetal body spaces, the diagnosis can be made. If fluid accumulation only occurs in one area, doctors cannot make the diagnosis of hydrops.
Why is hydrops fetalis in Rh incompatibility?
Causes. Hydrops fetalis usually stems from fetal anemia, when the heart needs to pump a much greater volume of blood to deliver the same amount of oxygen. This anemia can have either an immune or non-immune cause.
What is hydrops fetalis?
Hydrops fetalis — or hydrops — is a condition in which large amounts of fluid build up in a baby’s tissues and organs, causing extensive swelling (edema).
What is the treatment of erythroblastosis fetalis?
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.
Why is RhoGAM given?
RhoGAM is an immunity support injection administered during pregnancy for people with a negative blood type. The purpose of the RhoGAM shot is to prevent problems that occur due to the baby’s positive blood type. It helps prevent the body from developing Rh antibodies.
What level of fetal Hb is associated with fetal hydrops?
Hydrops Fetalis With Hb Bart Marked anasarca and enlargement of the liver and spleen are present. Severe anemia is usually present, with Hb levels of 3–10 g/dL.
Is hydrops fetalis hereditary?
The disorder is commonly inherited in an autosomal dominant fashion and leads to a mild to moderate anemia. The autosomal recessive form of hereditary spherocytosis is rarely reported in association with fetal anemia and hydrops fetalis.
Which vaccine is used in the treatment of erythroblastosis fetalis?
A preventive treatment known as RhoGAM, or Rh immunoglobulin, can reduce a mother’s reaction to their baby’s Rh-positive blood cells. This is administered as a shot at around the 28th week of pregnancy. The shot is administered again at least 72 hours after birth if the baby is Rh positive.
What causes non-immune hydrops fetalis (NIHF)?
A wide spectrum of genetic causes may lead to non-immune hydrops fetalis (NIHF), and a thorough phenotypic and genetic evaluation are essential to determine the underlying etiology, optimally manage these pregnancies, and inform discussions about anticipated prognosis.
What are the aetiological mechanisms of fetal hydrops?
The aetiological mechanisms leading to non-immune fetal hydrops are complex and their impact variable at different stages of gestation. In early pregnancy, primary or secondary intra-uterine cardiac failures due to major cardiovascular defects are more often linked to a chromosomal abnormality than during the second half of gestation.
What causes hydrops in non-immune diseases?
Metabolic disorders as a cause of non-immune hydrops. It has been recognized that a number of cases of non-immune hydrops were found to be secondary to lysosomal storage diseases and other metabolic disorders (6, 7).
What are the recommendations for the treatment of fetal hydrops?
Recommendations: 1. All patients with fetal hydrops should be referred promptly to a tertiary care centre for evaluation. Some conditions amenable to prenatal treatment represent a therapeutic emergency after 18 weeks. (II-2A) 2.
