The main cause of intrauterine hemolysis is blood group incompatibility between mother and child, and the symptoms of the fetus mainly include: fetal anemia, heart failure, edema, and fetal death in the womb.
1. Fetal anemia: when intrauterine hemolysis occurs, the red blood cells in the fetus will undergo abnormal changes, such as: lack of cellular enzymes, cell membrane abnormalities, and cellular hemoglobin composition defects, resulting in abnormal hemoglobin content in the fetus, and the symptoms of fetal anemia will appear.
2. Heart failure: intrauterine hemolysis leads to massive destruction of red blood cells in the newborn’s body, which may lead to anemia in the fetus. If the anemia is severe, the effective circulating blood volume of the fetus will be reduced, and the heart function will be impaired, which will lead to fetal heart failure in severe cases.
3. Edema: In intrauterine hemolysis, the plasma colloid osmotic pressure decreases due to the anemia of the newborn, and the fluid in the blood vessels penetrates into the tissue interstitial space, leading to the symptoms of edema in the fetus.
4. Fetal death in the uterus: if the symptoms of intrauterine hemolysis are more serious, the function of various organs of the fetus is seriously impaired, and may also endanger the life of the fetus, resulting in fetal death in the uterus.
Pregnant women with intrauterine hemolysis must consult a doctor in time to avoid delaying the condition and affecting the health of the mother and child.
