hydrops fetalis
Introduction
Introduction Systemic edema at birth is called fetal edema (hydropsfetalis) and often accompanied by serous effusion. Edema caused by various reasons after birth, said neonatal edema is more common in the lower back of the limbs and the perineum. Edema can start from a certain part of the body, and then the depression of the whole body edema pressure is called the depression. The depression is called non-recessed edema. In the fetus and newborn newborn, there is physiological edema due to extracellular fluid than intracellular fluid. This edema disappears within a few days after birth.
Cause
Cause
1. Immune edema refers to the immune hemolysis of a fetus or a newborn baby caused by a blood type incompatibility between a pregnant woman and a fetus. It is a blood group immune disease of the same family. Mainly caused by ABO blood type and Rh blood type incompatibility.
1) Rh blood group incompatibility, mainly occurs in the mother's blood type is Rh negative, fetal blood type is Rh positive. Rh blood type was Rh positive and Rh negative. Most people are Rh positive. The blood type of the mother is Rh negative. When the blood type of the fetus is Rh positive, the blood of the fetus is a foreign body to the blood of the mother, and thus antibodies against the blood of the fetus are generated, and the red blood cells of the fetus are gradually destroyed.
2) ABO blood group is incompatible. When O-type women and men other than O-type get married after pregnancy, some may cause ABO-type blood group incompatibility. However, compared with the Rh blood type, the newborn has very few severe jaundice.
Second, the common causes of non-immune edema are:
1) Cardiovascular malformations and abnormal cardiac function.
2) fetal lung malformation.
3) Abnormal placenta.
4) Causes of blood (such as maritime anemia). It mainly occurs on both sides of the parents who have maritime anemia.
5) Fetal chromosomal abnormalities.
6) Intrauterine infection with bacterial viruses (such as parvovirus, streptococcus, spirochetes, cytomegalovirus, coxsackie virus, toxoplasma, etc.).

Blood test fetal weight prediction
B-ultrasound is the most reliable and direct method for diagnosing fetal edema. In addition, we can further clarify the cause of the disease through blood group antibody screening, blood tests for children, chromosome examination, and virus detection.
Regular pregnancy check, B-ultrasound, malformation screening and fetal chromosome examination for pregnant women with high risk factors, help early detection of fetal edema, part of the treatment of intrauterine blood transfusion due to immune fetal edema, some of which are due to fetal malformation The pregnancy can be terminated as early as possible to avoid adverse consequences.
Diagnosis
Differential diagnosis
The diagnosis should be differentiated from the following symptoms:
1. Fetal distress: Children with hypoxia in the uterus endanger the health and life of the fetus, known as fetal distress.
2. Intrauterine asphyxia: Intrauterine asphyxia refers to the lack of oxygen in the uterus or excessive gas or respiratory disorders, and difficulty breathing or even stopping breathing.
